Having access to the director's list of currently running (and eventually the scheduled jobs) from python scripts would be very useful for me.

And as I like to do the next differential job that follows a full backup
also on a fresh tape, I am running the following SQL after completion of

Bacula aborted writing to the tape as the error occured and asked for a new volume. So maybe the last record that has been written to the tape before the error occured had been written correctly but the backup isn't complete as it needed another tape and it looks like it did not write the EOF successfully to the bad tape. So I doubt if the job could be used for a restore. (Unfortunately I cannot verify it because the tape has been wiped now.)

[Bacula-users] status storage fails to find pool
Hi!
I've just upgraded from 1.38.0 to 1.38.5.
So far everything works fine, I was able to run a successful incremental
backup.
However, the "status dir" command in the bacula console doesn't show the
correct pool any more:
snipp!

However, this tape should be in PoolDaily:

snipp!
Any hints why the pool isn't displayed correctly?
Btw.:
On my FC3 system, /dev/nst* and /dev/st* are created with ownership
root.disk and modes 0640:
/etc/udev/rules.d/50-udev.rules:
KERNEL=="st*", GROUP="disk", MODE="0640"
KERNEL=="nst*", GROUP="disk", MODE="0640"
The init-script in the RPM uses the group disk for the storage daemon.
This won't work without additional udev-rules because the group disk
doesn't have write permissions.
Besides, the storage daemon uses the MTSETDRVBUFFER ioctl in
set_os_device_parameters() which seems to work only for root:
Feb 9 12:59:12 samba bacula-sd: bacula-sd startup succeeded
Feb 9 12:59:12 samba kernel: st0: MTSETDRVBUFFER only allowed for root.

[Bacula-users] Automatically cancel differential jobs but not full jobs
Hi! I'm doing a full backup once a week and a differential backup on the other days. Differential jobs are backed up to a daily-tape-pool, full jobs are saved to a weekly pool. As the tapes sometimes are not changed in time, the jobs may have to wait for insertation of the right tape. To avoid having multiple same differential jobs in the waiting queue, I've set "Max Run Time" and "Max Start Delay" to 10h. However, this also results in cancelation of the full backup jobs, if the correct tape for the full-backup wasn't inserted in time. Is there a way to avoid having multiple jobs of the same kind queue up without loosing full-level jobs? I've tried "Rerun Failed Levels", hoping that the next differential jobs backup-level would be upgraded to "full" but this doesn't seem to work for jobs that were canceled because of wait-timeouts.

[Bacula-users] Label Media and cancelled jobs
Hi! I've experienced a problem where the storage daemon did automatically label a new tape for an already cancelled job. I'll try to outline my problem: A few days ago, the director tried to automatically create a new volume for my daily pool, because the pool didn't contain any acceptable volume for the job. However, the new tape was never inserted, instead of that, the job was canceled. The next scheduled job is a monthly hob, so a tape from the monthly-pool should be requested. Since there was no free tape, I inserted an empty one. But instead of leaving that tape blank and automatically labeling the tape when that scheduled monthly job starts, the storage daemon labeled the tape with a "daily"-label (the same label as for the new daily-tape that had been requested but never inserted). I had to unmount the tape and manually blank it to fix the problem. (Now, when mounting it again, the storage-daemon states: "open but no Bacula volume is mounted".) Maybe that label-request to the storage daemon wasn't properly cancelled by the director after the corresponding job had been cancelled? Is this a known problem?

[Bacula-users] Avoid queuing of multiple jobs with the same name
Hi! I've already posted a similar request back in May and I've been refered to Bug 307 but I believe the answer presented there this doesn't solve my problem. The problem was: I'm doing a full backup once a week and a differential backup on the other days. Differential jobs are backed up to a daily-tape-pool, full jobs are saved to a weekly pool. As the tapes sometimes are not changed in time, the jobs may have to wait for insertation of the right tape.

I've tried "Rerun Failed Levels", hoping that the next differential jobs backup-level would be upgraded to "full" but this doesn't seem to work for jobs that were canceled because of wait-timeouts. I've tried to use a "Run before job"-script that cancels the current job, if another one with with the same name and a higher or same level is already running (or waiting for a tape). Unfortunately the "Run before job"-Script isn't even executed because it is waiting for the other job. So an option to allow only one job with the same name in the scheduler's queue would be very useful. (Preferrable a higher level job should replace a lower level job that is already waiting in the queue.)

[Bacula-users] specify pool with the new run directive in job-resource
Hi!
I'd like to use the new Run-directive in the Job Resource to define a
job that should be run after the main backup-job. (This job should
backup the bacula database directory and is called BackupCatalog.)
However, since my schedule uses daily incremental backups that go to a
"PoolDaily" during the week, weekly full backups that go to "PoolWeekly"
and monthly full backups that go to "PoolMonthly", I'd like to specify
the BackupCatalog-Job to use the same pool as the main backup job and
hence use the same tape.
I'd like to use a variable like "%p" that is substituted for the pool,
that the current job is using, to allow starting the BackupCatalog-job
like that:
Job {
Name = "Samba-Homes"
Schedule = "WeeklyCycle"
[...]
Run = "BackupCatalog level=%l since=\"%s\" storage=DLT1 pool=%p"
}
I've found out that "%v" is substituted by the volume-name in
edit_job_codes() (in lib/util.c) but it looks like there is no variable
for the pool.
So I tried to add this feature using the attached patch.
However, it doesn't compile because the pool attribute is only compiled
into the class JCR, if DIRECTOR_DAEMON is defined. (See jcr.h)
Unfortunately, when lib/util.c is compiled, DIRECTOR_DAEMON isn't
defined. So jcr->pool isn't available at compile time in
edit_job_codes(). However, since jcr is passed from is passed from
do_backup_init() in dird/backup.c, it should be available at run-time.
I'd appreciate any hint at how to solve the problem...
Cheers,
--leo

Hmm - isn't it dangerous and error-prone anyways to have different
definitions of JCR in lib, director daemon, file daemon and storage
daemon and pass e.g. director jcr objects to methods in lib (and the
other way around)?
OK, the definition of the daemon-specific attributes (data members)
comes at the end of the class definition but I believe that it can be
potentially dangerous if the caller (e.g. do_backup_init() in the
director) has a different view of the object than the called function
(e.g. edit_job_codes() in libbac).
Taken from the O'Reilly book "Linux Device Drivers":
- snipp!
Another issue related to alignment is portability of data structures
across platforms. The same data structure (as defined in the C-language
source file) can be compiled differently on different platforms. The
compiler arranges structure fields to be aligned according to
conventions that differ from platform to platform. At least in theory,
the compiler can even reorder structure fields in order to optimize
memory usage.
- snipp!
I haven't found a similar abstract about c++ member alignment but at
least padding is also done when aligning c++ class members.
Recapitulationg I believe that it would be much more portable and a much
cleaner coding style to have all parts of baculas code use the same
class definitions.
If there is a common subset of data members that is used by all daemons
and a daemon specific part, inheritance (specialization) should be used,
the daemon's job control records should inherit from an abstract class
that defines the common part.

I planned to use the python interface anyways so I'll take a look into
that, thanks!

But that is what happens in the current code! do_backup_init() passes a jrc object (the version that has all the daemon specific members) to edit_job_codes(). But edit_job_codes() has a different view on the class than do_backup_init(). > My emphasis is going to be to try to do as much as possible with Python and > to > try to reduce the use of new % variables and directives as much as possible, > so a proper solution for me is one that involves Python.

This issue may as well affect two pieces of code compiled on a single platform, due to several source files using different class definitions resulting from the #ifdef's. Imagine the following scenario: First, when libbac is compiled, the compiler only sees a limited JCR class that contains the common members. The optimizer may arrange the members in a specific pattern. Then it compiles backup.c in the director's sources. Now it sees a different JCR class, additionally containing the director specific members. Now the optimizer may arrange the members in a different way than before which will lead to problems when passing an object between those two pieces of code. While the compiler will not change the order of the members on most platforms and will most likely use the same padding to align the members, this behaviour isn't something one should rely on. >>I haven't found a similar abstract about c++ member alignment but at >>least padding is also done when aligning c++ class members. >> >>Recapitulationg I believe that it would be much more portable and a much >>cleaner coding style to have all parts of baculas code use the same >>class definitions. >>If there is a common subset of data members that is used by all daemons >>and a daemon specific part, inheritance (specialization) should be used, >>the daemon's job control records should inherit from an abstract class >>that defines the common part. > > Bacula started out as C code, and it is slowly transitioning to C++.

Bacula-1.38 RPM Release Notes
[...]
*
* Fix for daemon user/group problem *
*
Prior to the 1.38.8 release the pre-install scripts attempted to create
the
user bacula with primary group as both bacula and disk which failed.
There was
still a problem with these scripts in 1.38.8, noted in bug 605, on
RedHat
platforms which by default attempt to create a group with same name as
the user
(bacula) and failed because it had already been created.
This has (I think) now been corrected with the addition of the -g
parameter to
the useradd commands and should work.
I think the order of user and groups has to be reversed.
The following code in the preinstall script fails on my FC5 box with:
usermod: user bacula,disk does not exist
if [ "$IS_ROOT" != "root" ]; then
/usr/sbin/usermod bacula -G bacula,disk
fi
However,
/usr/sbin/usermod -G bacula,disk bacula
... works as expected.
Besides, the src-rpms build really smooth, even on FC5 (using the
attached small spec-file patch). Thanks!
Cheers,

[Bacula-users] Scheduled job preview
Hi! In order to minimize operator interaction, I'd like to make bacula send an email containing the next n scheduled jobs, their levels and maybe a list of volumes that could be used for each job. The console command "status dir" only shows jobs scheduled for the next 24 hours. However, I don't have any jobs scheduled during the weekend, so a more general preview, that for example shows the next 3 scheduled jobs would be more useful in my case. Is there a way to produce such kind of output?

[Bacula-users] Concatenate Jobs
Hi! I'd like to run two Jobs, a "normal" backup-job that runs full or differential, followed by a Catalog-Backup that should always be a full backup. I've implemented it using two seperate consecutive schedules with different priorities now, following the example in the manual. However, this causes to two email status-notifications to be sent and could lead to configuration errors. Is there a way to configure a job to always append another one? (And maybe treat them as one.)

[Bacula-users] Volume Use Duration
Hi! The manual says that the Pool directive "Volume Use Duration" is only checked at the end of a job that writes to a volume. Is there a way to manually trigger this check? (E.g. to mark all "Appendable" daily volumes as Used when doing a full backup?) I could set the Volume Use Duration so that it will fire at the end of the last differential backup before a weekly full backup but the problem is that the last scheduled differential backup runs two days before the next full backup, because there are no scheduled jobs during the weekend. So I'd have to set the "Volume Use Duration" to 4 days. The problem with this setup is that I'd like to allow manual (differential) backups to this volume during the weekend, so I'd like to mark the volume as Used just before the Full backup is started. Is there a way to configure this behavior?
