Kern's ToDo List
- 15 September 2003
+ 27 January 2004
Documentation to do: (any release a little bit at a time)
- Document running a test version.
- 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.
-- Test not zeroing Autochanger slot when it is wrong.
-- Figure out how to use ssh or stunnel to protect Bacula communications.
-For 1.32:
-- Document list nextvol and new format status dir.
-- Document new records in Director. SDAddress SDDeviceName, SDPassword.
+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.
-- It is generally safe to use the drive when the lights stop flashing.
- Document new Include/Exclude ...
-- Document all the status codes JobLevel, JobType, JobStatus.
- Add test of exclusion, test multiple Include {} statements.
-- 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.
- when the magazine is changed.
-- Don't print "Warning: Wrong Volume mounted ..." if mounting second volume.
-- LabelFormat on tape volume apparently creates the db record but
- never actually labels the volume.
-- Copy static programs into install directory.
+- 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
For 1.33
-- Think about changing Storage resource Device record to be
- SDDeviceName.
+- Allow "delete job jobid=xx jobid=xxx".
+- Allow "delete job jobid=xxx,yyy,aaa-bbb" i.e. list + ranges.
+- Implement multiple Volume in "purge jobs volume=".
+- 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 timout BSOCK packets after a specific delay.
+- When I restore to Windows the Created, Accessed and Modifiedtimes are
+ those of the time of the restore, not those of the originalfile.
+ The dates you will find in your restore log seem to be the original
+ creation dates
+- Rescue builds incorrect script files on Rufus.
+- Write a Qmsg() to be used in bnet.c to prevent recursion. Queue the
+ message. If dequeueing toss the messages. Lock while dequeuing so that
+ it cannot be called recursively and set dequeuing flag.
+- Add all pools in Dir conf to DB also update them to catch changed
+ LabelFormats and such.
+- Symbolic link a directory to another one, then backup the symbolic
+ link.
+- Build console in client-only build.
+- Restore attributes of directory if replace=never set but directory
+ did not exist.
+- Check why Phil's Verify exclude does not work.
+- Phil says that Windows file sizes mismatch in Verify when they should,
+ and that either the file size or the catalog size was zero.
+- Fix option 2 of restore -- list where file is backed up -- require Client,
+ then list last 20 backups.
+- Allow browsing the catalog to see all versions of a file (with
+ stat data on each file).
+- Finish code passing files=nnn to restore start.
+- Add level to estimate command.
+- Check time/dates printed during restore when using Win32 API.
+- Volume "add"ed to Pool gets recycled in first use. VolBytes=0
+- Get rid of 0 dates in LastWritten, ...
+- Fix "llist jobid=xx" where no fileset or client exists.
+- Release SQLite 2.8.9
+- If a tape is recycled while it is mounted, Stanislav Tvrudy must do an
+ additional mount to deblock the job.
+- 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
+- To pass Include 1 or two letter commands
+ I Name Include name - first record
+ B Name Base name - repeat
+ R "xxx" Regexp
+ W "xxx" Wild Card
+ E zzz Exclude expression (wild card)
+ P "plugin" Plugin

+
+- Spooling ideas taken from Volker Sauer's and other's emails:

+ >
+ > 1) by job
+ > 2) by schedule
+ > 3) by sd
+ >
+ > where and 2) overrides 1) and 3) is independent.
+
+ Yes, this is the minimum that I think is necessary.
+
+ >
+ > Reason(s):
+ > It should be switched by job, because the job that backs up the machine
+ > with the bacula-sd on doesn't need spooling.

+
+ 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.
+
+ > And you should be able to turn it of by sd for sd-machines with low disk
+ > capacity or if you just don't need or want this feature.
+ >
+ > There should be:
+ > - definitly the possibility for multipe spool direcories
+
+ 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.
- 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.
+- Can we dynamically change FileSets?
- If pool specified to label command and Label Format is specified,
automatically generate the Volume name.
-- Take a careful look a the Basic recycling algorithm. When Bacula
- chooses, the order should be:
- - Look for Append

- - 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.
-
- Why can't SQL do the filename sort for restore?
-- Is a pool specification really needed for a restore? Yes, and
- you may want to exclude archive Pools.
- 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, ...)
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
-- 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.
-- Add Console usr permissions.
- Fix "restore all" to bypass building the tree.
-- Fix restore to list errors if Invalid block found, and if # files
- restored does not match # expected.
- 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.
-- Add JobName= to VerifyToCatalog so that all verifies can be done at the end.

- 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.
- If tape is marked read-only, then try opening it read-only rather than
failing, and remember that it cannot be written.
- 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.
-- Add RunBeforeJob and RunAfterJob to the Client program.
- 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.
- 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.
-- Need return status on read_cb() from read_records(). Need multiple
- records -- one per Job, maybe a JCR or some other structure with
- a block and a record.
- 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.
- Add UA rc and history files.
- put termcap (used by console) in ./configure and
allow -with-termcap-dir.
-- Enhance time and size scanning routines.
- Fix Autoprune for Volumes to respect need for full save.
- Fix Win32 config file definition name on /install
- Compare tape to Client files (attributes, or attributes and data)
- Make all database Ids 64 bit.
- Write an applet for Linux.
-- Implement new inter-daemon communications protocol.
- Allow console commands to detach or run in background.
- Fix status delay on storage daemon during rewind.
- Add SD message variables to control operator wait time

-Projects:
- Bacula Projects Roadmap
- 17 August 2002
- last update 8 May 2003
-
-Item 1: Multiple simultaneous Jobs. (done)
-Done -- Restore part needs better implementation to work correctly
- Also, it needs considerable testing
-
- What: Permit multiple simultaneous jobs in Bacula.
-
- Why: An enterprise level solution needs to go fast without the
- need for the system administrator to carefully tweak
- timing. Based on the benchmarks, during a full
- backup, NetWorker typically hit 10 times the bandwidth to
- the tape compared to Bacula--largely. This is probably due to
- running parallel jobs and multi-threaded filling of buffers
- and writing them to tape. This should also make things work
- better when you have a mix of fast and slow machines backing
- up at the same time.
-
- Notes: Bacula was designed to run multiple simultaneous jobs. Thus
- implementing this is a matter of some small cleanups and
- careful testing.
-
-
-Item 2: Make the Storage daemon use intermediate file storage to buffer data.
-Deferred -- not necessary yet -- possibly implement with Migration.
-
- What: If data is coming into the SD too fast, buffer it to
- disk if the user has configured this option.
-
- Why: This would be nice, especially if it more or less falls out
- when implementing (1) above. If not, it probably should not
- be given a high priority because fundamentally the backup time
- is limited by the tape bandwidth. Even though you may finish a
- client job quicker by spilling to disk, you still have to
- eventually get it onto tape. If intermediate disk buffering
- allows us to improve write bandwidth to tape, it may make
- sense.
-
- Notes: Whether or not this is implemented will depend upon performance
- testing after item 1 is implemented.
-
-
-Item 3: Write the bscan program -- also write a bcopy program.
-Done
-
- What: Write a program that reads a Bacula tape and puts all the
- appropriate data into the catalog. This allows recovery
- from a tape that is no longer in the database, or it allows
- re-creation of a database if lost.
-
- Why: This is a fundamental robustness and disaster recovery tool
- which will increase the comfort level of a sysadmin
- considering adopting Bacula.
-
- Notes: A skeleton of this program already exists, but much work
- needs to be done. Implementing this will also make apparent
- any deficiencies in the current Bacula tape format.
-
-
-Item 4: Implement Base jobs.
-
- What: A base job is sort of like a Full save except that you
- will want the FileSet to contain only files that are unlikely
- to change in the future (i.e. a snapshot of most of your
- system after installing it). After the base job has been run,
- when you are doing a Full save, you can specify to exclude
- all files saved by the base job that have not been modified.
-
- Why: This is something none of the competition does, as far as we know
- (except BackupPC, which is a Perl program that saves to disk
- only). It is big win for the user, it makes Bacula stand out
- as offering a unique optimization that immediately saves time
- and money.
-
- Notes: Big savings in tape usage. Will require more resources because
- the e. DIR must send FD a list of files/attribs, and the FD must
- search the list and compare it for each file to be saved.
-
-
-Item 5: Implement Label templates
-Done
-
- What: This is a mechanism whereby Bacula can automatically create
- a tape label for new tapes according to a detailed specification
- provided by the user.
-
- Why: It is a major convenience item for folks who use automated label
- creation.
-
- Notes: Bacula already has a working form of automatic tape label
- creation, but it is very crude. The design for the complete
- tape labeling project is already documented in the manual.
-
-
-Item 6: Write a regression script.
-Done -- Continue to expand its testing.
-
- What: This is an automatic script that runs and tests as many features
- of Bacula as possible. The output is compared to previous
- versions of Bacula and any differences are reported.
-
- Why: This is an enormous help in preventing introduction of new
- errors in parts of the program that already work correctly.
-
- Notes: This probably should be ranked higher, it's something the typical
- user doesn't see. Depending on how it's implemented, it may
- make sense to defer it until the archival tape format and
- user interface mature.
-
-
-Item 7: GUI for interactive restore
-Item 8: GUI for interactive backup
-
- What: The current interactive restore is implemented with a tty
- interface. It would be much nicer to be able to "see" the
- list of files backed up in typical GUI tree format.
- The same mechanism could also be used for creating
- ad-hoc backup FileSets (item 8).
-
- Why: Ease of use -- especially for the end user.
-
- Notes: Rather than implementing in Gtk, we probably should go directly
- for a Browser implementation, even if doing so meant the
- capability wouldn't be available until much later. Not only
- is there the question of Windows sites, most
- Solaris/HP/IRIX, etc, shops can't currently run Gtk programs
- without installing lots of stuff admins are very wary about.
- Real sysadmins will always use the command line anyway, and
- the user who's doing an interactive restore or backup of his
- own files will in most cases be on a Windows machine running
- Exploder.
-
-
-Item 9: Add SSL to daemon communications.
-
- What: This provides for secure communications between the daemons.
-
- Why: This would allow doing backup across the Internet without
- privacy concerns (or with much less concern).
-
- Notes: The vast majority of near term potential users will be backing up
- a single site over a LAN and, correctly or not, they probably
- won't be concerned with security, at least not enough to go to
- the trouble to set up keys, etc. to screw things down. We suspect
- that many users genuinely interested in multi-site backup
- already run some form of VPN software in their internetwork
- connections, and are willing to delegate security to that layer.
-
-
-Item 10: Define definitive tape format.
-Done (version 1.27)
-
- What: Define that definitive tape format that will not change
- for the next millennium.
-
- Why: Stability, security.
-
- Notes: See notes for item 11 below.
-
-
-Item 11: New daemon communication protocol.
-
- What: The current daemon to daemon protocol is basically an ASCII
- printf() and sending the buffer. On the receiving end, the
- buffer is sscanf()ed to unpack it. The new scheme would
- be a binary format that allows quick packing and unpacking
- of any data type with named fields.
-
- Why: Using binary packing would be faster. Named fields will permit
- error checking to ensure that what is sent is what the
- receiver really wants.
-
- Notes: These are internal improvements in the interest of the
- long-term stability and evolution of the program. On the one
- hand, the sooner they're done, the less code we have to rip
- up when the time comes to install them. On the other hand, they
- don't bring an immediately perceptible benefit to potential
- users. Item 10 and possibly item 11 should be deferred until Bacula
- is well established with a growing user community more or
- less happy with the feature set. At that time, it will make a
- good "next generation" upgrade in the interest of data
- immortality.

======================================================
It is somewhat like a Full save becomes an incremental since
the Base job (or jobs) plus other non-base files.
Need:
-- New BaseFile table that contains:
- JobId, BaseJobId, FileId (from Base).
+- 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,
- and FileId back to the Director who creates the DB entry.
+ 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

- Request For Comments For File Backup Options
+ Request For Comments For File Backup Options
10 November 2002
Subject: File Backup Options
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, ...)
- *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
Include {
Compression = GZIP;
Signature = MD5
- Match = /*.?*/ # matches all files.
+ Wild = /*.?*/ # matches all files.
File = /
}
}
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 as follows:
-
+ 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 {
- Options {
+ OptionSet {
Signature = MD5
# Note multiple Matches are ORed
- Match = /*.gz/ # matches .gz files */
- Match = /*.Z/ # matches .Z files */
+ Wild = "*.gz" # matches .gz files
+ Wild = "*.Z" # matches .Z files
}
- Options {
+ OptionSet {
Compression = GZIP
Signature = MD5
- Match = /*.?*/ # matches all files
+ Wild = "*.?*" # matches all files
}
File = /
}
- Is it necessary to provide some means of ANDing regular expressions
and negation? (not currently planned)
- e.g. Match = /*.gz/ && !/big.gz/
+ 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
Done: (see kernsdone for more)
-- Implement new alist in FileSet scanning.
-- bls should continue reading even if it finds Win32 data on the tape.
- The error should be Warning rather the Error.
-- Add user configurable timeout for connecting to SD.
-- Unsaved Flag in Job record (use JobMissingFiles).
-- Base Flag in Job record.
-- Configure mtx-changer to have correct path to mtx.
-- Add all command line arguments to "update", e.g. slot=nn volStatus=append, ...
-- Make some way so that if a machine is skipped because it is not up
- that Bacula will continue retrying for a specified period of time --
- periodically.
-- Implement all command line args on run.
-- Implement command line "restore" args.
-- Implement "restore current select=no"
-- Restore file modified before date
-- Restore -- do nothing but show what would happen
-- Add estimate to Console commands
-- Use read_record.c in SD code.
-- Fix read_record to handle multiple sessions.
-- Tip from Steve Allam
- mt -f /dev/nst0 defblksize 0
-- Document "status" in the console.
-- Document driving console from shell script.
-- Write JobMedia records with max file size is reached on tape.
-- Handle the case of multiple JobMedia records pending (i.e. the
- thread is slow and multiple situations requiring a JobMedia
- record occur).
-- Do performance analysis on the restore tree routines.
-- Fix maximum file size (block.c) to generate JobMedia records.
-- Make the default file size 1GB on the tape.
-- Implement forward spacing between files.
-- Add Machine type (Linux/Windows) to Status report for daemons.
- Look at src/host.h
-- Use repositioning at the beginning of the tape.
-- Do full check the command line args in update (e.g. VolStatus ...).
-- Specify list of files to restore

+=== 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.

+
+=== 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

+- 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)

+- 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
