[bacula/bacula] / bacula / kernstodo

                 Kern's ToDo List
                 28 February 2004

Documentation to do: (any release a little bit at a time)
- DB upgrade to version 5 in bacula-1.27b, DB upgrade to
  version 6 in 1.31; DB upgrade to version 7 in 1.33/4.
- Document running a test version.
- Document query file format.
- Document static linking
- Document problems with Verify and pruning.
- Document how to use multiple databases.
- For FreeBSD typical /dev/nrsa0 and for mtx /dev/pass1
- VXA drives have a "cleaning required"
  indicator, but Exabyte recommends preventive cleaning after every 75
  hours of operation.
  From Phil:
    In this context, it should be noted that Exabyte has a command-line
    vxatool utility available for free download.  (The current version is
    vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
    test the drive, unload tapes, change drive settings, flash new firmware,
    etc.
    Of particular interest in this context is that vxatool <device> -i will
    report, among other details, the time since last cleaning in tape motion
    minutes.  This information can be retrieved (and settings changed, for
    that matter) through the generic-SCSI device even when Bacula has the
    regular tape device locked.  (Needless to say, I don't recommend
    changing tape settings while a job is running.)
- Lookup HP cleaning recommendations.
- Lookup HP tape replacement recommendations (see trouble shooting autochanger)
- Create a man page for each binary (Debian package requirement).
          
Testing to do: (painful)
- Test drive polling!
- that ALL console command line options work and are always implemented
- blocksize recognition code.
- Test if rewind at end of tape waits for tape to rewind.
- Test cancel at EOM.       

For 1.33 Testing/Documentation:
- Newly labeled tapes are chosen before ones already in use.
- Document new alias records in Director. SDAddress SDDeviceName, SDPassword.
  FDPassword, FDAddress, DBAddress, DBPort, DBPassword.
- Document new Include/Exclude ...
- Add test of exclusion, test multiple Include {} statements.
- Add counter variable test.
- Document ln -sf /usr/lib/libncurses.so /usr/lib/libtermcap.so
  and install the esound-dev  package for compiling Console on SuSE.
  This should read 'Document LDFLAGS="-L/usr/lib/termcap" ... '
- Add an example of using a FIFO in dirdconf.wml 
- Add an item to the FAQ about running jobs in different timezones.
- Add some examples of job editing codes.

- Document Dan's new --with-dir-user, ... options.
  See userid.txt
- Figure out how to use ssh or stunnel to protect Bacula communications.
  Add Dan's work to manual See ssl.txt
- Add db check test to regression. Test each function like delete,
  purge, ...
- Add subsections to the Disaster Recovery index section.
- Document Pool keyword for restore.
- If you use restore replace=never, the directory attributes for
  non-existent directories will not be restored properly.
- In the Bacula User Guide you write:"Note, one major disadvantage of
  writing to a NFS mounted volume as I do isthat if the other machine goes
  down, the OS will wait forever on the fopen()call that Bacula makes.  As
  a consequence, Bacula will completely stall untilthe machine exporting
  the NSF mounts comes back up.  If someone knows a wayaround this, please
  let me know."I haven't tried using NFS in years, but I think that the
  "soft" and "intr"remount options may well help you.  The only way of
  being sure would be totry it.See, for example,
     http://howtos.linux.com/guides/nag2/x-087-2-nfs.mountd.shtml

  then list last 20 backups.
- Allow browsing the catalog to see all versions of a file (with 
  stat data on each file).

- From Johan Decock:
  bscan: sql_update.c:65 UPDATE File SET MD5='Ij+5kwN6TFIxK+8l8+/I+A' WHERE FileId=0
  bscan: bscan.c:1074 Could not add MD5/SHA1 to File record. ERR=sql_update.c:65 Update problem: affected_rows=0
- Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and   
  ua_status.!!! Thanks to Alan Brown for this tip.
- Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
  correctly for multiple simultaneous jobs.
- Correct code so that FileSet MD5 is calculated for < and | filename   
  generation.
- Mark Volume in error on error from WEOF.
- Why does Bacula need the drive open to do "autochanger list" ?
- Add a .list all files in the restore tree (probably also a list all files)
  Do both a long and short form.
- Implement the Media record flag that indicates that the Volume does disk 
  addressing.
- Implement VolAddr, which is used when Volume is addressed like a disk,
  and form it from VolFile and VolBlock.
- Make multiple restore jobs for multiple media types specifying 
  the proper storage type.
- Implement MediaType keyword in bsr?   
- Fix fast block rejection (stored/read_record.c:118). It passes a null
  pointer (rec) to try_repositioning().
- Look at extracting Win data from BackupRead.
- Having dashes in filenames apparently creates problems for restore
  by filename.
- Add data compare on write/read in btape "test". 
- Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
  which would take precidence over the Catalog "JobRetention".
- Implement Label Format in Add and Label console commands.
- Possibly up network buffers to 65K. Put on variable.
- Put email tape request delays on one or more variables. User wants
  to cancel the job after a certain time interval.  Maximum Mount Wait?
  Job, Client, Device, Pool, or Volume?
  Is it possible to make this a directive which is *optional* in multiple
  resources, like Level? If so, I think I'd make it an optional directive
  in Job, Client, and Pool, with precedence such that Job overrides Client
  which in turn overrides Pool.
- Print a message when a job starts if the conf file is not current.
- Finish work on conio.c

   Yes, this is the minimum that I think is necessary.

   True, with the exception that if you have enough disk spool space,
   and you want to run concurrent jobs, spooling can eliminate the block
   interleaving restore inefficiencies.

   Having multiple directories is no problem -- having different maximum
   sizes creates specification problems.  At some point, I will probably
   have a common SD pool of spool directories as well as a set of
   private spool directories for each device.  The first implementation
   will be a set of private spool directories for each device since
   managing a global pool with a bunch of threads writing into the same
   directory is *much* more complicated and prone to error.

   > - the ability to spool parts of a backup (not the whole client)

   This may change in the future, but for the moment, it will spool
   either to a job high water mark, or until the directory is full
   (reaches max spool size or I/O error).  It will then write to tape,
   truncate the spool file, and begin spooling again.

   > - spooling while writing to tape

   Not within a job, but yes, if you run concurrent jobs -- each is a
   different thread.  Within a job could be a feature, but *much* later.

   > - parallel spooling (like parallel jobs/ concurrent jobs) of clients

   Yes, this is one of my main motivations for doing it (aside from
   eliminating tape "shoe shine" during incremental backups.

   > - flushing a backup that only went to disk (like amflush in amanda)

   This will be a future feature, since spooling is different from backing
   up to disk. The future feature will be "migration" which will move a job
   from one backup Volume to another.

- New Storage specifications:
  Passed to SD as a sort of BSR record called Storage Specification
    Record or SSR.
    SSR                    
      Next -> Next SSR
      MediaType -> Next MediaType
      Pool -> Next Pool
      Device -> Next Device
  Write Copy Resource that makes a copy of a resource.
  Job Resource
     Allow multiple Storage specifications
     New flags
        One Archive = yes
        One Device = yes
        One Storage = yes
        One MediaType = yes
        One Pool = yes
  Storage
     Allow Multiple Pool specifications (note, Pool currently
       in Job resource).
     Allow Multiple MediaType specifications
     Allow Multiple Device specifications
     Perhaps keep this in a single SSR
  Tie a Volume to a specific device by using a MediaType that 
    is contained in only one device.
  In SD allow Device to have Multiple MediaTypes

After 1.33:
- Look at www.nu2.nu/pebuilder as a helper for full windows
  bare metal restore.
From Chris Hull:
   it seems to be complaining about 12:00pm which should be a valid 12
   hour time.  I changed the time to 11:59am and everything works fine.
   Also 12:00am works fine.  0:00pm also works (which I don't think
   should).  None of the values 12:00pm - 12:59pm work for that matter.
Ideas from Jerry Scharf:
  First let's point out some big pluses that bacula has for this
        it's open source
        more importantly it's active. Thank you so much for that
        even more important, it's not flaky
        it has an open access catalog, opening many possibilities
        it's pushing toward heterogeneous systems capability
  simple things:
        I don't remember an include file directive for config files
                (not filesets, actual config directives)
        can you check the configs without starting the daemon?
        some warnings about possible common mistakes
  big things:
   doing the testing and blessing of concurrent backup writes
        this is absolutely necessary in the enterprise
   easy user recovery GUI with full access checking
   Macintosh file client
        macs are an interesting niche, but I fear a server is a rathole
   working bare iron recovery for windows
   much better handling on running config changes
        thinking through the logic of what happens to jobs in progress
   the option for  inc/diff backups not reset on fileset revision
        a) use both change and inode update time against base time
        b) do the full catalog check (expensive but accurate)
   sizing guide (how much system is needed to back up N systems/files)
   consultants on using bacula in building a disaster recovery system
   an integration guide
        or how to get at fancy things that one could do with bacula
   logwatch code for bacula logs (or similar)
   linux distro inclusion of bacula (brings good and bad, but necessary)
   win2k/XP server capability (icky but you asked)
   support for Oracle database ??
===
- Look at adding SQL server and Exchange support for Windows. 
- Restore: Enter Filename: 'C:/Documents and Settings/Comercial/My
  Documents/MOP/formulário de registro BELAS ARTES.doc' causes Bacula to
  crash.
- Each DVD-RAM disk would be a volume, just like each tape is 
  a volume. It's a 4.7GB media with random access, but there's nothing about 
  it that I can see that makes it so different than a tape from  bacula's 
  perspective. Why couldn't I back up to a bare floppy as a volume (ignoring 
  the media capacity?)
- Make dev->file and dev->block_num signed integers so that -1 can
  be an invalid value which happens with BSR.
- Create VolAddr for disk files in place of VolFile and VolBlock. This
  is needed to properly specify ranges.
- Print bsmtp output to job report so that problems will be seen.
- Pass the number of files to be restored to the FD for reporting 
- Add progress of files/bytes to SD and FD.
- Don't continue Restore if no files selected.
- Print warning message if FileId > 4 billion
- do a "messages" before the first prompt in Console
- Add a date and time stamp at the beginning of every line in the 
  Job report (Volker Sauer).
- Client does not show busy during Estimate command.
- Implement Console mtx commands.
- Add a default DB password to MySQL.  
  GRANT all privileges ON bacula.* TO bacula@localhost IDENTIFIED BY 
     'bacula_password';
  FLUSH PRIVILEGES;
- Implement a Mount Command and an Unmount Command where
  the users could specify a system command to be performed
  to do the mount, after which Bacula could attempt to
  read the device. This is for Removeable media such as a CDROM.
  - Most likely, this mount command would be invoked explicitly
  by the user using the current Console "mount" and "unmount" 
  commands -- the Storage Daemon would do the right thing 
  depending on the exact nature of the device.
  - As with tape drives, when Bacula wanted a new removable
  disk mounted, it would unmount the old one, and send a message
  to the user, who would then use "mount" as described above 
  once he had actually inserted the disk.
- Implement dump/print label to UA
- Implement disk spooling. Two parts: 1. Spool to disk then
  immediately to tape to speed up tape operations. 2. Spool to
  disk only when the tape is full, then when a tape is hung move
  it to tape.
- Scratch Pool where the volumes can be re-assigned to any Pool.
- bextract is sending everything to the log file ****FIXME****
- Add Progress command that periodically reports the progress of
  a job or all jobs.
- Restrict characters permitted in a Resource name, and don't permit
  duplicate names.
- Allow multiple Storage specifications (or multiple names on
  a single Storage specification) in the Job record. Thus a job 
  can be backed up to a number of storage devices.
- Implement some way for the File daemon to contact the Director 
  to start a job or pass its DHCP obtained IP number.
- Implement multiple Consoles.
- Implement a query tape prompt/replace feature for a console
- From Johan?
    Two jobs ready to go, first one blocked waiting for media
    Cancel 2nd job ("waiting execution" one)
    Cancel blocked job
    boom - segfault*
- Copy console @ code to gnome2-console
- Make AES the only encryption algorithm see 
  http://csrc.nist.gov/CryptoToolkit/aes/).  It's
  an officially adopted standard, has survived peer
  review, and provides keys up to 256 bits.
- Add ctl-c to console to stop current command and discard buffered
  output.
- Estimate to Tibs never returns.
- Think about how space could be freed up on a tape -- perhaps this
  is a Merge or Compact feature that is needed.
- Modify FileSet, did not upgrade the current Increment job, but
  waited for the next job to be upgraded.
- Take a careful look at SetACL http://setacl.sourceforge.net     
- Implement a where command for the tree telling where a file
  is located.
- Take a careful look at Level for the estimate command, maybe make
  it a command line option.
- Add Volume name to "I cannot write on this volume because"
- Make tree walk routines like cd, ls, ... more user friendly
  by handling spaces better.
- Write your PID file and chown root:wheel before drop.
- Make sure there is no symlink in a file before creating a
  file (attack).
- Look at mktemp or mkstemp(3).
    mktemp and mkstemp create files with predictable names too.  That's
    not the vulnerability.  The vulnerability is in creating files without
    using the O_EXCL flag, which means "only create this file if it doesn't
    exist, including if the file is a dangling symlink."

    It is *NOT* enough to do the equivalent of

      if doesn't exist $filename
       then create $filename

    because between the test and the create another process could have
    gotten the CPU and created the file.  You must use atomic functions
    (those that don't get interrupted by other processes) and O_EXCL is
    the only way for this particular example.
- Automatically create pools, but instead of looking for what
  in in Job records, walk through the pool resources.
- Check and double check tree code, why does it take so long?
- Add device name to "Current Volume not acceptable because ..."
- Make sure that Bacula rechecks the tape after the 20 min wait.
- Set IO_NOWAIT on Bacula TCP/IP packets.
- Try doing a raw partition backup and restore by mounting a
  Windows partition.
- From Lars Kellers:
    Yes, it would allow to highly automatic the request for new tapes. If a 
    tape is empty, bacula reads the barcodes (native or simulated), and if 
    an unused tape is found, it runs the label command with all the 
    necessary parameters.

    By the way can bacula automatically "move" an empty/purged volume say 
    in the "short" pool to the "long" pool if this pool runs out of volume 
    space?
- Eliminate orphaned jobs: dbcheck, normal pruning, delete job command.
  Hm.  Well, there are the remaining orphaned job records:

     |   105 | Llioness Save  | 0000-00-00 00:00:00 | B    | D     |        0 |             0 | f         |
     |   110 | Llioness Save  | 0000-00-00 00:00:00 | B    | I     |        0 |             0 | f         |
     |   115 | Llioness Save  | 2003-09-10 02:22:03 | B    | I     |        0 |             0 | A         |
     |   128 | Catalog Save   | 2003-09-11 03:53:32 | B    | I     |        0 |             0 | C         |
     |   131 | Catalog Save   | 0000-00-00 00:00:00 | B    | I     |        0 |             0 | f         |

     As you can see, three of the five are failures.  I already deleted the
     one restore and one other failure using the by-client option.  Deciding
     what is an orphaned job is a tricky problem though, I agree.  All these
     records have or had 0 files/ 0 bytes, except for the restore.  With no
     files, of course, I don't know of the job ever actually becomes
     associated with a Volume.

     (I'm not sure if this is documented anywhere -- what are the meanings of
     all the possible JobStatus codes?)

     Looking at my database, it appears to me as though all the "orphaned"
     jobs fit into one of two categories:

     1)  The Job record has a StartTime but no EndTime, and the job is not
         currently running;
     or
     2)  The Job record has an EndTime, indicating that it completed, but
         it has no associated JobMedia record.


     This does suggest an approach.  If failed jobs (or jobs that, for some
     other reason, write no files) are associated with a volume via a
     JobMedia record, then they should be purged when the associated volume
     is purged.  I see two ways to handle jobs that are NOT associated with a
     specific volume:

     1)  purge them automatically whenever any volume is manually purged;
     or
     2)  add an option to the purge command to manually purge all jobs with
         no associated volume.

     I think Restore jobs also fall into category 2 above ....  so one might
     want to make that "The Job record has an EndTime,, but no associated
     JobMedia record, and is not a Restore job."  
- make "btape /tmp" work.
- Make sure a rescheduled job is properly reported by status.
- Walk through the Pool records rather than the Job records
  in dird.c to create/update pools.
- What to do about "list files job=xxx".
- When job rescheduled, status gives is waiting for Client Rufus 
  to connect to Storage File. Dir needs to inform SD that job
  is rescheduled.
- Make Dmsg look at global before calling subroutine.
- Enable trace output at runtime for Win32
- Available volumes for autochangers (see patrick@baanboard.com 3 Sep 03 
  and 4 Sep) scan slots.
- Get and test MySQL 4.0
- Do a complete audit of all pthreads_mutex, cond, ... to ensure that
  any that are dynamically initialized are destroyed when no longer used.
- Look at how fuser works and /proc/PID/fd that is how Nic found the
  file descriptor leak in Bacula.
- Implement WrapCounters in Counters.
- Turn on SIGHUP in dird.c and test.
- Use system dependent calls to get more precise info on tape errors.
- Add heartbeat from FD to SD if hb interval expires.
- Suppress read error on blank tape when doing a label.
- Can we dynamically change FileSets?
- If pool specified to label command and Label Format is specified,
  automatically generate the Volume name.
- Why can't SQL do the filename sort for restore?
- Look at libkse (man kse) for FreeBSD threading.
- Look into Microsoft Volume Shadowcopy Service VSS for backing
  up system state components (Active Directory, System Volume, ...)
- Add ExhautiveRestoreSearch
- Look at the possibility of loading only the necessary 
  data into the restore tree (i.e. do it one directory at a
  time as the user walks through the tree).
- Possibly use the hash code if the user selects all for a restore command.
- Orphaned Dir buffer at parse_conf.c:373 =>  store_dir
- Fix "restore all" to bypass building the tree.
- Prohibit backing up archive device (findlib/find_one.c:128)
- Implement Release Device in the Job resource to unmount a drive.
- Implement Acquire Device in the Job resource to mount a drive,
  be sure this works with admin jobs so that the user can get
  prompted to insert the correct tape.  Possibly some way to say to
  run the job but don't save the files.
- Implement FileOptions (see end of this document)
- Make things like list where a file is saved case independent for
  Windows.
- Implement migrate
- Bacula needs to propagate SD errors.

- Use autochanger to handle multiple devices.
- Add SuSE install doc to list.
- Check and rechedk "Invalid block number"
- Make bextract release the drive properly between tapes 
  so that an autochanger can be made to work.
- User wants to NOT backup up certain big files (email files).
- Maybe remove multiple simultaneous devices code in SD.
- On Windows with very long path names, it may be impossible to create 
  a file (and thus restore it) because the total length is too long.
  We must cd into the directory then create the file without the
  full path name.
- lstat() is not going to work on Win32 for testing date.
- Implement a Recycle command
- Add client name to cram-md5 challenge so Director can immediately
  verify if it is the correct client.
- Add JobLevel in FD status (but make sure it is defined).
- Audit all UA commands to ensure that we always prompt where possible.
- Check Jmsg in bnet, may not work, must dup bsock.
- Suppress Job Name in Jmsg for console
- Create Pools that are referenced in a Run statement at startup if possible.
- Use runbeforejob to unload, then reload a volume previously used,
  then the next job run gets an error reading the drive.
- Make bootstrap filename unique.
- Test a second language e.g. french.
- Start working on Base jobs.
- Make "make binary-release" work from any directory.
- Implement UnsavedFiles DB record.
- Implement argc/argv for daemon command line scanning using table driven
  stuff below.
- Implement table driven single argc/argv scanner to pickup all arguments.
  Much like xxx_conf.c scan table.
  keyword, handler(store_routine), store_address, code, flags, default.
- From Phil Stracchino:
  It would probably be a per-client option, and would be called
  something like, say, "Automatically purge obsoleted jobs".  What it
  would do is, when you successfully complete a Differential backup of a
  client, it would automatically purge all Incremental backups for that
  client that are rendered redundant by that Differential.  Likewise,
  when a Full backup on a client completed, it would automatically purge
  all Differential and Incremental jobs obsoleted by that Full backup.
  This would let people minimize the number of tapes they're keeping on
  hand without having to master the art of retention times.
- Implement a M_SECURITY message class.
- When doing a Backup send all attributes back to the Director, who
  would then figure out what files have been deleted.
- Currently in mount.c:236 the SD simply creates a Volume. It should have
  explicit permission to do so.  It should also mark the tape in error
  if there is an error.
- Make sure all restore counters are working correctly in the FD.
- SD Bytes Read is wrong.
- Look at ALL higher level routines that call block.c to be sure
  they don't expect something in errmsg.
- Investigate doing RAW backup of Win32 partition.
- Add thread specific data to hold the jcr -- send error messages from
  low level routines by accessing it and using Jmsg().
- Cancel waiting for Client connect in SD if FD goes away.

- Examine Bare Metal restore problem (a FD crash exists somewhere ...).
- Implement timeout in response() when it should come quickly.
- Implement console @echo command.
- Implement a Slot priority (loaded/not loaded).
- Implement "vacation" Incremental only saves.
- Implement single pane restore (much like the Gftp panes).
- Implement Automatic Mount even in operator wait.
- Implement create "FileSet"?
- Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
- Implement "scratch pool" where tapes are defined and can be
  taken by any pool that needs them.
- Implement restore "current system", but take all files without
  doing selection tree -- so that jobs without File records can
  be restored.
- Add prefixlinks to where or not where absolute links to FD.
- Issue message to mount a new tape before the rewind.
- Simplified client job initiation for portables.
- If SD cannot open a drive, make it periodically retry.
- Add more of the config info to the tape label.

- If tape is marked read-only, then try opening it read-only rather than
  failing, and remember that it cannot be written.
- Refine SD waiting output:
    Device is being positioned
    >     Device is being positioned for append
    >     Device is being positioned to file x
    > 
- Figure out some way to estimate output size and to avoid splitting
  a backup across two Volumes -- this could be useful for writing CDROMs
  where you really prefer not to have it split -- not serious.
- Have SD compute MD5 or SHA1 and compare to what FD computes.
- Make VolumeToCatalog calculate an MD5 or SHA1 from the 
  actual data on the Volume and compare it.                  
- Implement Bacula plugins -- design API
- Make bcopy read through bad tape records.
- Program files (i.e. execute a program to read/write files).
  Pass read date of last backup, size of file last time.
- Add Signature type to File DB record.
- CD into subdirectory when open()ing files for backup to
  speed up things.  Test with testfind().
- Priority job to go to top of list.
- Why are save/restore of device different sizes (sparse?)   Yup! Fix it.
- Implement some way for the Console to dynamically create a job.
- Restore to a particular time -- e.g. before date, after date. 
- Solaris -I on tar for include list
- Need a verbose mode in restore, perhaps to bsr.
- bscan without -v is too quiet -- perhaps show jobs.
- Add code to reject whole blocks if not wanted on restore.
- Check if we can increase Bacula FD priorty in Win2000
- Make sure the MaxVolFiles is fully implemented in SD
- Check if both CatalogFiles and UseCatalog are set to SD.
- Figure out how to do a bare metal Windows restore
- Possibly add email to Watchdog if drive is unmounted too
  long and a job is waiting on the drive.
- Restore program that errs in SD due to no tape, reports
  OK incorrectly in output.
- After unmount, if restore job started, ask to mount.
- Convert all %x substitution variables, which are hard to remember
  and read to %(variable-name).  Idea from TMDA.
- Remove NextId for SQLite. Optimize.
- Move all SQL statements into a single location.

  reading a new config file at any time.
- Handle ctl-c in Console
- Implement script driven addition of File daemon to config files.
- Think about how to make Bacula work better with File (non-tape) archives.
- Write Unix emulator for Windows.
- Put memory utilization in Status output of each daemon
  if full status requested or if some level of debug on.
- Make database type selectable by .conf files i.e. at runtime
- Set flag for uname -a.  Add to Volume label.
- Implement throttled work queue.
- Restore files modified after date
- SET LD_RUN_PATH=$HOME/mysql/lib/mysql
- Implement Restore FileSet=
- Create a protocol.h and protocol.c where all protocol messages
  are concentrated.
- Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).

=====
- FD sends unsaved file list to Director at end of job (see
  RFC below).
- File daemon should build list of files skipped, and then
  at end of save retry and report any errors.
- Write a Storage daemon that uses pipes and
  standard Unix programs to write to the tape.
  See afbackup.
- Need something that monitors the JCR queue and
  times out jobs by asking the deamons where they are.
- Enhance Jmsg code to permit buffering and saving to disk.
- device driver = "xxxx" for drives.
- Verify from Volume
- Ensure that /dev/null works
- Need report class for messages. Perhaps
  report resource where report=group of messages
- enhance scan_attrib and rename scan_jobtype, and
  fill in code for "since" option 
- Director needs a time after which the report status is sent
  anyway -- or better yet, a retry time for the job.
- Don't reschedule a job if previous incarnation is still running.
- Some way to automatically backup everything is needed????
- Need a structure for pending actions:
  - buffered messages
  - termination status (part of buffered msgs?)
- Drive management
  Read, Write, Clean, Delete
- Login to Bacula; Bacula users with different permissions:
   owner, group, user, quotas
- Store info on each file system type (probably in the job header on tape.
  This could be the output of df; or perhaps some sort of /etc/mtab record.

Longer term to do:
- Design at hierarchial storage for Bacula. Migration and Clone. 
- Implement FSM (File System Modules).
- Audit M_ error codes to ensure they are correct and consistent.
- Add variable break characters to lex analyzer.
  Either a bit mask or a string of chars so that
  the caller can change the break characters.
- Make a single T_BREAK to replace T_COMMA, etc.
- Ensure that File daemon and Storage daemon can
  continue a save if the Director goes down (this
  is NOT currently the case). Must detect socket error,
  buffer messages for later. 
- Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
- Add ability to backup to two Storage devices (two SD sessions) at
  the same time -- e.g. onsite, offsite.
- Add the ability to consolidate old backup sets (basically do a restore
  to tape and appropriately update the catalog). Compress Volume sets.
  Might need to spool via file is only one drive is available.
- Compress or consolidate Volumes of old possibly deleted files. Perhaps
  someway to do so with every volume that has less than x% valid 
  files.


Migration: Move a backup from one Volume to another
Clone:     Copy a backup -- two Volumes

Bacula Migration is based on Jobs (apparently Networker is file by file).

Migration triggered by:
  Number of Jobs
  Number of Volumes
  Age of Jobs
  Highwater mark (keep total size)
  Lowwater mark
  


======================================================
        Base Jobs design
It is somewhat like a Full save becomes an incremental since
the Base job (or jobs) plus other non-base files.
Need:
- A Base backup is same as Full backup, just different type.
- New BaseFiles table that contains:
    BaseId - index
    BaseJobId - Base JobId referenced for this FileId (needed ???)
    JobId - JobId currently running
    FileId - File not backed up, exists in Base Job
    FileIndex - FileIndex from Base Job.
  i.e. for each base file that exists but is not saved because
  it has not changed, the File daemon sends the JobId, BaseId,
  FileId, FileIndex back to the Director who creates the DB entry.
- To initiate a Base save, the Director sends the FD 
  the FileId, and full filename for each file in the Base.
- When the FD finds a Base file, he requests the Director to
  send him the full File entry (stat packet plus MD5), or
  conversely, the FD sends it to the Director and the Director
  says yes or no. This can be quite rapid if the FileId is kept
  by the FD for each Base Filename.          
- It is probably better to have the comparison done by the FD
  despite the fact that the File entry must be sent across the
  network.
- An alternative would be to send the FD the whole File entry
  from the start. The disadvantage is that it requires a lot of
  space. The advantage is that it requires less communications
  during the save.
- The Job record must be updated to indicate that one or more
  Bases were used.
- At end of Job, FD returns:   
   1. Count of base files/bytes not written to tape (i.e. matches)
   2. Count of base file that were saved i.e. had changed.
- No tape record would be written for a Base file that matches, in the
  same way that no tape record is written for Incremental jobs where
  the file is not saved because it is unchanged.
- On a restore, all the Base file records must explicitly be
  found from the BaseFile tape. I.e. for each Full save that is marked
  to have one or more Base Jobs, search the BaseFile for all occurrences
  of JobId.
- An optimization might be to make the BaseFile have:
     JobId
     BaseId
     FileId
  plus
     FileIndex
  This would avoid the need to explicitly fetch each File record for
  the Base job.  The Base Job record will be fetched to get the
  VolSessionId and VolSessionTime.

          Request For Comments For File Backup Options
                   10 November 2002

Subject: File Backup Options

Problem: 
  A few days ago, a Bacula user who is backing up to file volumes and
  using compression asked if it was possible to suppress compressing
  all .gz files since it was a waste of CPU time. Although Bacula
  currently permits using different options (compression, ...) on
  a directory by directory basis, it cannot do it on a file by 
  file basis, which is clearly what was desired.   

Proposed Implementation:
  To solve this problem, I propose the following:

  - Add a new Director resource type called Options.  

  - The Options resource will have records for all
    options that can currently be specified on the Include record 
    (in a FileSet).  Examples below.

  - The Options resource will permit an exclude option as well
    as a number of additional options.

  - The heart of the Options resource is the ability to
    supply any number of Match records which specify POSIX
    regular expressions.  These Match regular expressions are
    applied to the fully qualified filename (path and all). If
    one matches, then the Options will be used.

  - When an Match specification matches an included file, the
    options specified in the Options resource will override
    the default options specified on the Include record.

  - Include records will be modified to permit referencing one or
    more Options resources.  The Options will be used
    in the order listed on the Include record and the first
    one that matches will be applied.

  - Options (or specifications) currently supplied on the Include
    record will be deprecated (i.e. removed in a later version a
    year or so from now).

  - The Exclude record will be deprecated as the same functionality
    can be obtained by using an Exclude = yes in the Options.

Options records:
  The following records can appear in the Options resource. An
  asterisk preceding the name indicates a feature not currently
  implemented.

    - Regexp "xxx"            - Match regular expression
    - Wild "xxx"              - Do a wild card match

  For Backup Jobs:
    - Compression= (GZIP, ...)
    - Signature=   (MD5, SHA1, ...)
    - *Encryption=
    - OneFs=      (yes/no)    - remain on one filesystem
    - Recurse=    (yes/no)    - recurse into subdirectories
    - Sparse=     (yes/no)    - do sparse file backup
    - *Exclude=   (yes/no)    - exclude file from being saved
    - *Reader=    (filename)  - external read (backup) program
    - *Plugin=    (filename)  - read/write plugin module

    - Include=    (yes/no)    - Include the file matched no additional
                                patterns are applied.

  For Verify Jobs:
    - verify=     (ipnougsamc5) - verify options

  For Restore Jobs:
    - replace= (always/ifnewer/ifolder/never) - replace options currently
                                                implemented in 1.31
    - *Writer= (filename)   - external write (restore) program


Implementation:
  Currently options specifying compression, MD5 signatures, recursion,
  ... of a FileSet are supplied on the Include record. These will now
  all be collected into a Options resource, which will be
  specified in the Include in place of the options. Multiple Options
  may be specified.  Since the Options may contain regular expressions
  that are applied to the full filename, this will give the ability
  to specify backup options on a file by file basis to whatever level
  of detail you wish.

Example:

  Today:

    FileSet {
      Name = "FullSet"
      Include = compression=GZIP signature=MD5 {
        /
      }
    }

  Proposal:

    FileSet {
      Name = "FullSet"
      Include {
        Compression = GZIP;
        Signature = MD5
        Wild  = /*.?*/                # matches all files.
        File = /
      }
    }

  That's a lot more to do the same thing, but it gives the ability to
  apply options on a file by file basis.  For example, suppose you
  want to compress all files but not any file with extensions .gz or .Z.
  In that case, you will need to group two sets of options using
  the Options resource. Files may be anywhere except in an
  option set???  All OptionSets apply to all files in the order
  the OptionSets were specified.  To have files included with
  different option sets without using wild-cards, use two or more
  Includes -- each one is handled in turn using only the files and
  optionsets specified in the include.

    FileSet {
      Name = "FullSet"
      Include {
        OptionSet {
          Signature = MD5
          # Note multiple Matches are ORed
          Wild  = "*.gz"   # matches .gz files
          Wild  = "*.Z"    # matches .Z files
        }
        OptionSet {
          Compression = GZIP
          Signature = MD5
          Wild  = "*.?*"   # matches all files
        }
        File = /
      }
    }

  Now, since the no Compression option is specified in the
  first group of Options, *.gz or *.Z file will have an MD5 signature computed,
  but will not be compressed. For all other files, the *.gz *.Z will not
  match, so the second group of options will be used which will include GZIP
  compression.

Questions:
  - Is it necessary to provide some means of ANDing regular expressions
    and negation?  (not currently planned)

    e.g.  Wild  = /*.gz/ && !/big.gz/

  - I see that Networker has a "null" module which, if specified, does not 
    backup the file, but does make an record of the file in the catalog
    so that the catalog will reflect an exact picture of the filesystem.
    The result is that the file can be "seen" when "browsing" the save
    sets, but it cannot be restored.
    
    Is this really useful?  Should it be implemented in Bacula?
  
Results:
  After implementing the above, the user will be able to specify
  on a file by file basis (using regular expressions) what options are
  applied for the backup.


=============================================

========================================================== 
    Unsaved File design
For each Incremental job that is run, there may be files that
were found but not saved because they were locked (this applies
only to Windows). Such a system could send back to the Director
a list of Unsaved files.
Need:
- New UnSavedFiles table that contains:
  JobId
  PathId
  FilenameId
- Then in the next Incremental job, the list of Unsaved Files will be
  feed to the FD, who will ensure that they are explicitly chosen even
  if standard date/time check would not have selected them.
=============================================================


Done: (see kernsdone for more)

=== after 1.32c
- John's Full save failed with 1.32c FD and 1.31 Dir no FD status,
  and no error message.
- Add fd and st as Console keywords.
- Recycling volume with a Slot requires an operator intervention:
    rufus-dir: Start Backup JobId 18, Job=kernsave.2003-11-01_21.23.52
    rufus-dir: Pruned 1 Job on Volume Vol01 from catalog.
    rufus-dir: There are no Jobs associated with Volume Vol01. Marking it purged.
    rufus-dir: Recycled volume "Vol01"
    rufus-sd: Please mount Volume "Vol01" on Storage Device "DDS-4" for Job kernsave.2003-11-01_21.23.52
    Use "mount" command to release Job.
- Implement Dan's bacula script (email of 26 Oct).
- Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
- Edit the Client/Storage name into authentication failure messages.
- Fix packet too big problem. This is most likely a Windows TCP stack 
  problem.
- Implement ClientRunBeforeJob and ClientRunAfterJob.
- Implement forward spacing block/file: position_device(bsr) --
  just before read_block_from_device();

   Unloading Data Transfer Element into Storage Element 15...done

   (just to verify it remembers where it came from, however it can be
    overrriden with mtx unload {slotnumber} to go to any storage slot.)
   Configuration wise:
   There needs to be a table of drive # to devices somewhere - If there are
   multiple changers or drives there may not be a 1:1 correspondance between
   changer drive number and system device name - and depending on the way the
   drives are hooked up to scsi busses, they may not be linearly numbered
   from an offset point either.something like 

   Autochanger drives = 2
   Autochanger drive 0 = /dev/nst1
   Autochanger drive 1 = /dev/nst2
   IMHO, it would be _safest_ to use explicit mtx unload commands at all
   times, not just for multidrive changers. For a 1 drive changer, that's
   just:

   mtx load xx 0
   mtx unload xx 0

   MTX's manpage (1.2.15):
         unload [<slotnum>] [ <drivenum> ]
                    Unloads media from drive  <drivenum>  into  slot
                    <slotnum>. If <drivenum> is omitted, defaults to
                    drive 0 (as do all commands).  If  <slotnum>  is
                    omitted, defaults to the slot that the drive was
                    loaded from. Note that there's currently no  way
                    to  say  'unload  drive 1's media to the slot it
                    came from', other than to  explicitly  use  that
                    slot number as the destination.AB

   Handling removable disks

   From: Karl Cunningham <karlc@keckec.com>

   My backups are only to hard disk these days, in removable bays. This is my
   idea of how a backup to hard disk would work more smoothly. Some of these
   things Bacula does already, but I mention them for completeness. If others
   have better ways to do this, I'd like to hear about it.

   1. Accommodate several disks, rotated similar to how tapes are.  Identified
   by partition volume ID or perhaps by the name of a subdirectory.
   2. Abort & notify the admin if the wrong disk is in the bay.
   3. Write backups to different subdirectories for each machine to be backed
   up.
   4. Volumes (files) get created as needed in the proper subdirectory, one
   for each backup.
   5. When a disk is recycled, remove or zero all old backup files. This is
   important as the disk being recycled may be close to full. This may be
   better done manually since the backup files for many machines may be
   scattered in many subdirectories.

=== for 1.33
- Change console to bconsole.
- Change smtp to bsmtp.
- Fix time difference problem between Bacula and Client
  so that everything is in GMT.
- Fix TimeZone problem!
- Mount a tape that is not right for the job (wrong # files on tape)
  Bacula asks for another tape, fix problems with first tape and
  say "mount". All works OK, but status shows:
   Device /dev/nst0 open but no Bacula volume is mounted.
       Total Bytes=1,153,820,213 Blocks=17,888 Bytes/block=64,502
       Positioned at File=9 Block=3,951
   Full Backup job Rufus.2003-10-26_16.45.31 using Volume "DLT-24Oct03" on device /dev/nst0
       Files=21,003 Bytes=253,954,408 Bytes/sec=2,919,016
       FDReadSeqNo=192,134 in_msg=129830 out_msg=5 fd=7
- Upgrade to cygwin 1.5
- Optimize fsf not to read.
- Use ioctl() fsf if it exists. Figure out where we are from
  the mt_status command. Use slow fsf only if other does not work.
- Enhance "update slots" to include a "scan" feature
  scan 1; scan 1-5; scan 1,2,4 ...  to update the catalog 
- Allow a slot or range of slots on the label barcodes command.
- Finish implementation of Verify=DiskToCatalog
- Make sure that Volumes are recycled based on "Least recently used"
  rather than lowest MediaId.
- Add flag to write only one EOF mark on the tape.
- Implement autochanger testing in btape "test" command.
- Implement lmark to list everyfile marked.
- Make mark/unmark report how many files marked/unmarked.
- Keep last 5 or 10 completed jobs and show them in a similar list.
- Make a Running Jobs: output similar to current Scheduled Jobs:
- Change "create_media_record in bscan to use Archive instead of Full.
- Have some way to estimate the restore size or have it printed.
- Volume problems occurs if you have valid volume, written, then it is
  truncated. You get 12-Nov-2003 11:48 rufus-sd: kernsave.2003-11-12_11.48.09 Warning: mount.c:228 Volume on /tmp is not a Bacula labeled Volume, because:
     block.c:640 Read zero bytes on device /tmp.
- Make sure that 64 bit I/O packets are used on Cygwin.
- Add to supported autochangers 
  OS              : FreeBSD-4.9
  Auto-Changer    : QUALSTAR TLS-4210
    Manufufactur  : Qualstar
    Tapes         : 12 (AIT1: 36GB, AIT2: 50GB all uncompressed)
    Drives        : 2xAIT2 (installed in the Qualstar: SONY SDX-500C AIT2)
- Document estimate command in tree.
- Document lsmark command in tree.
- Setup a standard job that builds a bootstrap file and saves
  it with the catalog database.
- See if a restore job can add a file to the tape (prohibit this).
- Restrict characters permitted in a name.
- In restore, provide option for limiting to a particular Pool.
- In restore, list FileSets that only have different base names --
  i.e. any FileSet with the same name should be treated as the same.
- Make Scheduler sort jobs by StartTime, Priority.
- Make sure smtp and any other useful program is executable by the world
  in case Bacula is not running as root.
- Look at Dan's field width problems in PostgreSQL.
- Look at effect of removing GROUP BYs.
- In restore take all filesets with same base name.
- From Alan Brown <ajb2@mssl.ucl.ac.uk>
    BTW, there's a make install bug in 1.33 - with --enable-gnome,
    gnome-console is built, but the binary and .conf are not being installed.
- Permit Bacula and apcupsd donations (not done for apcupsd).
- Fix Ctl-C crashing the Console (readline?).
- Look at code in recycle_oldes_purged_volume() recycle.c. Why not
  let SQL do ORDER BY LastWritten ASC?
- Look at find_next_volume() algorithm. Currently, it selects:
    +---------+------------+---------------------+-----------+
    | MediaId | VolumeName | LastWritten         | VolBytes  |
    +---------+------------+---------------------+-----------+
    |       3 | Test13     | 0000-00-00 00:00:00 |         1 |
    |       4 | Test14     | 0000-00-00 00:00:00 |         1 |
    |       1 | test11     | 2003-12-03 18:39:55 | 4,004,926 |
    |       2 | test12     | 2004-01-04 15:25:56 | 2,078,691 |
    +---------+------------+---------------------+-----------+
  but perhaps it should fill already used Volumes first, and use
  Append volumes before Purged, or Recycled, ...
- Possibly remove the "|| ap == NULL" on lines 123 and 207 of lib/var.c,
  which creates compile problems on alpha systems.
  var.c:123: no match for `va_list & == long int'
- Check "restore" 3 (JobId), then it asks for Storage resource. Does
  it verify that the correct volume is chosen?
- Make Bacula "poll a drive".
- Notes for final checking of Nic's code:
  Could I get you to double check the switch () statements in the
  job_check_maxwaittime and job_check_maxruntime functions in
  src/dird/job.c?
- Define week of year for scheduler.  W01, W02, ...
  Week 01 of a year is per definition the first week that has the
  Thursday in this year, which is equivalent to the week that contains the
  fourth day of January.  In other words, the first week of a new year is
  the week that has the majority of its days in the new year.  Week 01
  might also contain days from the previous year and the week before week
  01 of a year is the last week (52 or 53) of the previous year even if it
  contains days from the new year.  A week starts with Monday (day 1) and
  ends with Sunday (day 7).  For example, the first week of the year 1997
  lasts from 1996-12-30 to 1997-01-05 and can be written in standard
  notation as
    1997-W01 or 1997W01
  The week notation can also be extended by a number indicating the day
  of the week.  For example, the day 1996-12-31, which is the Tuesday (day
  2) of the first week of 1997, can also be written as
    1997-W01-2 or 1997W012
- Either restrict the characters in a name, or fix the problem 
  emailing with names containing / (smtp command line breaks).
- Implement .consolerc for Console
- Implement scan: for every slot it finds, zero the slot of
  Volume other volume having that slot.
- Make restore job check if all the files are actually restored.
- Look at 2Gb limit for SQLite.
- Fix get_storage_from_media_type (ua_restore) to use command line     
  storage=
- Don't print "Warning: Wrong Volume mounted ..." if mounting second volume.
- Write a mini-readline with history and editing.
- Take a careful look a the Basic recycling algorithm.  When Bacula
  chooses, the order should be:
   - Look for Append
   - Look for Recycle or Purged
   - Prune volumes
   - Look for purged
  Instead of using lowest media Id, find the least recently used
  volume.

  When the tape is mounted and Bacula requests the status
  - Do everything possible to use it.

  Define a "available" status, which is the currently mounted 
  Volume and all volumes that are currently in the autochanger.
- Is a pool specification really needed for a restore?  Yes, and
  you may want to exclude archive Pools.
- Implement a PostgreSQL driver.
- Fix restore to list errors if Invalid block found, and if # files
  restored does not match # expected.
- Something is not right in last block of fill command.
- Add FileSet to command line arguments for restore.
- Enhance time and size scanning routines.
- Add Console usr permissions -- do by adding filters for
  jobs, clients, storage, ...
- Put max network buffer size on a directive.
- Why does "mark cygwin" take so long!!!!!!!!
- Implement alist processing for ACLs from Console.
- When a file is set for restore, walk back up the chain of 
  directories, setting them to be restored.
- Figure out a way to set restore on a directory without recursively
  decending.  (recurse off?).
- Fix restore to only pull in last Differential and later Incrementals.
- Implement 3 Pools for a Job:
   Job {
     Name = ...
     Full Backup Pool = xxx
     Incremental Backup Pool = yyy
     Differential Backup Pool = zzz
   }
- Look at ASSERT() at 384 src/lib/bnet.c
- Dates are wrong in restore list from Win32 FD.
- Dates are wrong in catalog from Win32 FD.
- Remove h_errno from bnet.c by including proper header.
