                    Kern's ToDo List
                     20 October 2004

Version 1.35                Kern (see below)
========================================================

1.35 Items to do for release:
- Finish recovering from a disaster situation.   
  - How to get back a catalog.
  

Maybe for 1.35:
- Scratch Pool where the volumes can be re-assigned to any Pool.
- Update StartTime if job held in Job Queue.
- Despool attributes simultaneously with data in a separate
  thread, rejoined at end of data spooling.
- Implement Files/Bytes,... stats for restore job.
- Implement Total Bytes Written, ... for restore job.
- Check dates entered by user for correctness (month/day/... ranges)
- Compress restore Volume listing by date and first file.
- Add Pool/Storage override regression test.
- Add delete JobId to regression.
- Add bscan to four-concurrent-jobs regression.
- Look at patches/bacula_db.b2z postgresql that loops during restore.
  See Gregory Wright.
- Add IPv6 to regression
- Perhaps add read/write programs and/or plugins to FileSets.
- How to handle backing up portables ...
- Add "Rerun failed levels = yes/no" to Job resource.
- Add some sort of guaranteed Interval for upgrading jobs.
- Can we write the state file after every job terminates? On Win32
  the system crashes and the state file is not updated.
- Limit bandwidth

Documentation to do: (any release a little bit at a time)
- Doc to do unmount before removing magazine.
- Alternative to static linking "ldd prog" save all binaries listed,
  restore them and point LD_LIBRARY_PATH to them.
- Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
- Document query file format.
- Add more documentation for bsr files.
- Document problems with Verify and pruning.
- Document how to use multiple databases.
- 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)
- Document doing table repair
  
          
Testing to do: (painful)


For 1.37 Testing/Documentation:
- Add bandwidth limiting.
- Add acks every once and a while from the SD to keep
  the line from timing out.
- When an error in input occurs and conio beeps, you can back
  up through the prompt.
- Detect fixed tape block mode during positioning by looking at
  block numbers in btape "test".  Possibly adjust in Bacula.
- Implement a Client filename case fold option (default = fold
  on Win32).
- Fix list volumes to output volume retention in some other
  units, perhaps via a directive.
- If opening a tape in read/write mode fails attempt to open
  it in read-only mode, and mark the tape for read only.
- Add a read-only mode to the mount option.
- Add "Allow multiple connections" in Catalog resource to open a new 
  database connection for each job.
- Allow Simultaneous Priorities = yes  => run up to Max concurrent jobs even
  with multiple priorities.
- Fix find_device in stored/dircmd.c:462 (see code) 
- Add db check test to regression. Test each function like delete,
  purge, ...
- If you use restore replace=never, the directory attributes for
  non-existent directories will not be restored properly.

Fix:
   Kern,
   mt status and tapeinfo output are attached. Default blocksize was
   originally 512 bytes. I ran the following test on my machine:

   - set defblksize to 512
   - started bacula, labelled tape, ran job
   - job completes with the following in log
           SD termination status:  OK
           Termination:            Backup OK
   - restore attempts with blocksize set to 0 or 512 result in the familiar
           "Volume data error! Wanted block-id BB02, got . Buffer discarded."

Wish list:  
- see lzma401.zip in others directory for new compression
  algorithm/library.
- Minimal autochanger handling in Bacula and in btape.
- Look into how tar does not save sockets and the possiblity of
  not saving them in Bacula (Martin Simmons reported this).
- Add All Local Partitions = yes to new style saves.
- localmounts=`awk '/ext/ { print $2 }' /proc/mounts`   # or whatever
  find $localmounts -xdev -type s -ls
- Fix restore jobs so that multiple jobs can run if they
  are not using the same tape(s).
- Allow the user to select JobType for manual pruning/purging.
- Look at adding Client run command that will use the
  port opened by the client.
- bscan does not put first of two volumes back with all info in
  bscan-test.
- Implement the FreeBSD nodump flag in chflags.
- Figure out how to make named console messages go only to that
  console and to the non-restricted console (new console class?).
- Make restricted console prompt for password if *ask* is set or
  perhaps if password is undefined.
- Implement "from ISO-date/time every x hours/days/weeks/months" in
  schedules.
==== from Marc Schoechlin
- the help-command should be more verbose
  (it should explain the paramters of the different 
  commands in detail)
  -> it´s time-comsuming to consult the manual anytime
     you need a special parameter
  -> maybe it´s more easy to maintain this, if the
     descriptions of that commands are outsourced to
     a ceratin-file
- the cd-command should allow complete paths
  i.e. cd /foo/bar/foo/bar
  -> if a customer mails me the path to a certain file,
     it´s faster to enter the specified directory
- if the password is not configured in bconsole.conf
  you should be asked for it.
  -> sometimes you like to do restore on a customer-machine
     which shouldn´t know the password for bacula.
  -> adding the password to the file favours admins
     to forget to remove the password after usage
  -> security-aspects
     the protection of that file is less important
- long-listed-output of commands should be scrollable
  like the unix more/less-command does
  -> if someone runs 200 and more machines, the lists could
     be a little long and complex
- command-output should be shown column by column
  to reduce scrolling and to increase clarity
  -> see last item
- lsmark should list the selected files with full
  paths
- wildcards for selecting and file and directories would be nice
- any actions should be interuptable with STRG+C
- command-expansion would be pretty cool
====
- Compaction of Disk space by "migrating" Volumes that have pruned
  Jobs (what criteria? size, #jobs, time).
- Add prune all command
- Document fact that purge can destroy a part of a restore by purging
  one volume while others remain valid -- perhaps mark Jobs.
- Add multiple-media-types.txt
- look at mxt-changer.html
- Make ? do a help command (no return needed).
- Implement restore directory.
- Document streams and how to implement them.
- Possibly implement "Ensure Full Backup = yes" looks for a failed full backup
  and upgrades the current backup if one exists.
- Check that barcode reading and update slots scan works.
- Try not to re-backup a file if a new hard link is added.
- Add feature to backup hard links only, but not the data.
- Fix stream handling to be simpler.
- Add Priority and Bootstrap to Run a Job.
- Eliminate Restore "Run Restore Job" prompt by allowing new "run command
  to be issued"
- Remove View FileSet button from Run a Job dialog.
- Don't count higher level non-saved directories in Files expected
  in restore report.
- Handle prompt for restore job at end of Restore command.
- Add display of total selected files to Restore window.
- Add tree pane to left of window.
- Add progress meter.
- Max wait time or max run time causes seg fault -- see runtime-bug.txt
- Document writing to a CD/DVD with Bacula.
- Add a "base" package to the window installer for pthreadsVCE.dll
  which is needed by all packages.
- Add message to user to check for fixed block size when the forward
  space test fails in btape.
- When unmarking a directory check if all files below are unmarked and
  then remove the + flag -- in the restore tree.
- Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
- Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
- Revisit the question of multiple Volumes (disk) on a single device.
- Add a block copy option to bcopy.
- Investigate adding Mac Resource Forks.
- Finish work on Gnome restore GUI.
- Fix "llist jobid=xx" where no fileset or client exists.
- 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.
- Add level to estimate command.
- For each job type (Admin, Restore, ...) require only the really necessary
  fields.
- Fix option 2 of restore -- list where file is backed up -- require Client,
  then list last 20 backups.
- Add all pools in Dir conf to DB also update them to catch changed
  LabelFormats and such.
- Pass Director resource name as an option to the Console.
- Add a "batch" mode to the Console (no unsolicited queries, ...).
- Add a .list all files in the restore tree (probably also a list all files)
  Do both a long and short form.
- Allow browsing the catalog to see all versions of a file (with 
  stat data on each file).
- Restore attributes of directory if replace=never set but directory
  did not exist.
- Use SHA1 on authentication if possible.
- See comtest-xxx.zip for Windows code to talk to USB.
- Make btape accept Device Names in addition to Archive names.
- Add Events and Perl scripting.
- Add John's appended files:
   Appended = {     /files/server/logs/http/*log   }
   and such files would be treated as follows.On a FULL backup, they would
   be backed up like any other file.On an INCREMENTAL backup, where a
   previous INCREMENTAL or FULL was already in thecatalogue and the length
   of the file wasgreater than the length of the last backup, only thedata
   added since the last backup will be dumped.On an INCREMENTAL backup, if
   the length of the file is less than thelength of the file with the same
   name last backed up, the completefile is dumped.On Windows systems, with
   creation date of files, we can be evensmarter about this and not count
   entirely upon the length.On a restore, the full and all incrementals
   since it will beapplied in sequence to restore the file.  
- Add a regression test for dbcheck.  
- Add disk seeking on restore.  - Allow
   for optional cancelling of SD and FD in case DIR
  gets a fatal error. Requested by Jesse Guardiani <jesse@wingnet.net>
- Add "limit=n" for "list jobs"
- Check new HAVE_WIN32 open bits.    
- Check if the tape has moved before writing.  
- Handling removable disks -- see below:
- Keep track of tape use time, and report when cleaning is necessary.
- Add FromClient and ToClient keywords on restore command (or
  BackupClient RestoreClient).
- Implement a JobSet, which groups any number of jobs. If the
  JobSet is started, all the jobs are started together.
  Allow Pool, Level, and Schedule overrides.
- Enhance cancel to timeout BSOCK packets after a specific delay.
- 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.
- 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.
- 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.

   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:
  - Want to write to multiple storage devices simultaneously
  - Want to write to multiple storage devices sequentially (in one job)
  - Want to read/write simultaneously
  - Key is MediaType -- it must match

  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
  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 in Dir conf
     Allow Multiple Device specifications in Dir conf
     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.
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
  big things:
   Macintosh file client
        macs are an interesting niche, but I fear a server is a rathole
   working bare iron recovery for windows
   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
- Spool to disk only when the tape is full, then when a tape is hung move
  it to tape.
- 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.
- 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.

- 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.

  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.

  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.

- 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.

- 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.

  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.

Subject: RE: [Bacula-users] future large programming jobs
Date: Thu, 26 Feb 2004 11:34:54 -0600

I noticed the subject thread and thought I would offer the following
merely as sources of ideas, i.e. something to think about, not even as
strong as a request.  In my former life (before retiring) I often
dealt with backups and storage management issues/products as a
developer and as a consultant.  I am currently migrating my personal
network from amanda to bacula specifically because of the ability to
cross media boundaries during storing backups.
Are you familiar with the commercial product called ADSM (I think IBM
now sells it under the Tivoli label)?  It has a couple of interesting
ideas that may apply to the following topics.

1. Migration:  Consider that when you need to restore a system, there
may be pressure to hurry.  If all the information for a single client
can eventually end up on the same media (and in chronological order),
the restore is facillitated by not having to search past information
from other clients.  ADSM has the concept of "client affinity" that
may be associated with it's storage pools.  It seems to me that this
concept (as an optional feature) might fit in your architecture for
migration.

ADSM also has the concept of defining one or more storage pools as
"copy pools" (almost mirrors, but only in the sense of contents).
These pools provide the ability to have duplicte data stored both
onsite and offsite.  The copy process can be scheduled to be handled
by their storage manager during periods when there is no backup
activity.  Again, the migration process might be a place to consider
implementing something like this.

This is the goal. In the first step (before events), you simply
schedule
the Migration to tape later.

2. Base jobs:  In ADSM, each copy of each stored file is tracked in
the database.  Once a file (unique by path and metadata such as dates,
size, ownership, etc.) is in a copy pool, no more copies are made.  In
other words, when you start ADSM, it begins like your concept of a
base job.  After that it is in the "incremental" mode.  You can
configure the number of "generations" of files to be retained, plus a
retention date after which even old generations are purged.  The
database tracks the contents of media and projects the percentage of
each volume that is valid.  When the valid content of a volume drops
below a configured percentage, the valid data are migrated to another
volume and the old volume is marked as empty.  Note, this requires
ADSM to have an idea of the contents of a client, i.e. marking the
database when an existing file was deleted, but this would solve your
issue of restoring a client without restoring deleted files.

This is pretty far from what bacula now does, but if you are going to
rip things up for Base jobs,.....
Also, the benefits of this are huge for very large shops, especially
with media robots, but are a pain for shops with manual media
mounting.

>
> Base jobs sound pretty useful, but I'm not dying for them.

Nobody is dying for them, but when you see what it does, you will die
without it.

3. Restoring deleted files:  Since I think my comments in (2) above
have low probability of implementation, I'll also suggest that you
could approach the issue of deleted files by a mechanism of having the
fd report to the dir, a list of all files on the client for every
backup job.  The dir could note in the database entry for each file
the date that the file was seen.  Then if a restore as of date X takes
place, only files that exist from before X until after X would be
restored.  Probably the major cost here is the extra date container in
each row of the files table.

Thanks for "listening".  I hope some of this helps.  If you want to
contact me, please send me an email - I read some but not all of the
mailing list traffic and might miss a reply there.

Please accept my compliments for bacula.  It is doing a great job for
me!!  I sympathize with you in the need to wrestle with excelence in
execution vs. excelence in feature inclusion.

Jerry Schieffer

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

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.
=========================================================  


========================================================== 
    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.

- New IP address specification is used as follows:
    [sdaddresses|diraddresses|fdaddresses] = { [[ip|ipv4|ipv6] = { 
           [[addr|port] = [^ ]+[\n;]+] }] }

  so it could look for example like this:
     SDaddresses  = { ip = {
            addr = 1.2.3.4; port = 1205; }
        ipv4 = {
            addr = 1.2.3.4; port = http; }
        ipv6 = {
            addr = 1.2.3.4;
            port = 1205;
        }
        ip = {
            addr = 1.2.3.4
            port = 1205
        }
        ip = {
            addr = 1.2.3.4
        }
        ip = {
            addr = 201:220:222::2
        }
        ip = {
            addr = bluedot.thun.net
        }
     }
  as a consequence, you can now specify multiple IP addresses and
  ports to be used. In the case of a server, it will listen on
  all those that you specify. In the case of connecting to the server,
  Bacula will attempt connecting to one at a time until it succeeds.
  And, in a few other special cases, Bacula will use only the first
  address specified.

  The default port numbers are still the same and the services and hosts 
  are also resolved by name. So now  you could use the real names for the 
  port numbers.

  An ip section will allow resolution to either an ipv4 or an ipv6 address.
  An ipv4 section forces the resolution to be only ipv4, and an ipv6 section
  forces the resolution to be only ipv6.
