Re: [Bacula-users] Retention period calculation

[Justin Case]

Thanks for clarifying this, Ana,

so if I wanted my tier 1 storage to keep backups for 60 days, and my tier 2 
storage to keep backups for 120 days, would it be the best to set the retention 
periods as follows in the different resources:?
• client resources:
• file retention: 60
• job retention: 60
• tier1 pool resources:
• volume retention 70
• tier 2 pool resources:
• file retention 120
• job retention 120
• volume retention 130

Or what else would you propose?

Thank you for your time and effort!

Hello Justin,

Sorry for the confusion!
You are right, we recommend that *VolumeRetention is greater than or equal
to JobRetention".

So, the Volume will never get pruned before the Job Retention has expired.

Hope it is clear now.

Best,
Ana

Re: [Bacula-users] Retention period calculation

[Ana Emília M . Arruda]

Hello Justin,

The problem is that you expect the Job doesn't get pruned from the Catalog
(Job and File records deleted from the Bacula database) *before* the
JobRetention value expires.
If you have a lower VolumeRetention and the volume gets pruned by using
"prune volume expired yes", your jobs will be pruned before the
JobRetention value.

And when the volume gets pruned, volstatus=Purged, it can be potentially
reused by Bacula or truncated and the job data in the volume gets deleted.

This is why we usually recommend:

JobRetention greater than or equal to VolumeRetention

This guarantees that jobs get pruned only when JobRetention has expired.
And your data is safe in the volume at least until JobRetention is reached.

Best,
Ana

Re: [Bacula-users] Retention period calculation

Hello Ana,

I though about what you wrote and I am still wondering what would be the 
problem if a volume gets purged before the contained jobs retentions expire? 
This would remove the jobs and the corresponding files also from the catalog, 
ok, but where is the problem?
I am Just trying to get a better understanding.

Re: [Bacula-users] Retention period calculation

[Ana Emília M . Arruda]

Hello Antonino,

Please note that Job, File and Volume retention values are related to
"Catalog stuff". They are the retention of the Jobs and File records in the
Catalog.
Bacula doesn't touch the data in the volumes unless the volume gets reused
or truncated.
When you prune jobs, files or volumes, you are "deleting the jobs/files
records from the Catalog database".

If you prune a volume, it means you delete the jobs and files records
associated with this volume from the Catalog.

Thus, "CATALOGRETENTION" is not used in Bacula.

Hope this helps!

Best,
Ana

Re: [Bacula-users] Retention period calculation

[Antonino Balsamo]

Thanks Ana and good spot.

CATALOGRETENTION is the value I use for all catalog related stuff (job, 
file and volume), maybe is redundant...


Updated calc:

RETENTION=2 FILERETENTION=$(($RETENTION*30+40))
VOLUMERETENTION=$(($RETENTION*30+40))
JOBRETENTION=$(($RETENTION*30+40))
CATALOGRETENTION=$(($RETENTION*30+90))

Cheers

There are only three retention values in Bacula: File, Job and Volume. 
I strongly recommend you to set JobRetention less than or equal to 
VolumeRetention to avoid the volume to be pruned before the Job 
Retention has expired.

Re: [Bacula-users] Retention Period

[Wanderlei Huttel]

Hello Ken

You must change the "Volume Retention" in the Pool Resource.
And after that is necessary to run the command "update" in the bconsole to
apply the changes vor volumes previously written.

*update
1: Volume parameters
14: All Volumes from all Pools

Best regards

Re: [Bacula-users] Retention Period not working?

[Jim Richardson]

Please dig into the rationale for “I delete the oldest tapes from this pool” ??

If you are manually deleting the tape Volume or changing the Pool, you are 
changing the Volume information, the restore wizard is linked to the “at the 
time of run” job, pool, and volume information in order to produce the list.  
This may be why you see the correct information when you specify the job id.  
If your retention for Volumes needs to be 365 days, as you have configured, let 
Bacula purge/recycle volumes.  I have found the easiest way is to use the 
‘Recycle Oldest Volume’ directive to recycle the oldest tapes in the Pool 
currently in your library.  If you are replacing 3 tapes every month and you 
have 36 tapes in rotation, the oldest 3 will be purged and recycled as the 
running jobs need them.  My experience is if you are replacing tapes and 
updating the slots appropriately there should never be a need to manually 
delete Volumes or change Pools.  Volumes physically moved to off site will move 
to Slot 0 “removed” until reinserted into your library.  They will naturally 
purge and recycle per configured retention periods and in a jam the oldest will 
be used to ensure the running job completes (say if the job grows to a fourth 
tape).  If you want to have a pool for just Off-Site monthlies create a pool 
for OffSite, use the pool override option in your schedule resource to assign 
it when the monthlies run.  When you return the tapes to the library the above 
‘Recycle Oldest Volume’ option will be sure they are recycled first.

I hope that helps.

Hello Expert,

We have been using Bacula Version: 7.4.0.
Recently we introduced Offsite backup pool with N no. of tapes. The retention

File Retention : 92 Days
Job Retention : 92 Days

Every month we take offsite backup and the respective tapes move out of the

I use 3 sets for this so that I delete the oldest tapes from this pool and add 
the tapes from next-backup-cycle set (which was previously kept aside).
In order to verify , I tried to do restore for one of the hosts and surprised 
to found that it allows me to choose only from 1 Set.

Re: [Bacula-users] Retention period - last written date, and time?

[Gi Dot]

Yes, I understand that. But for such setup like recycling the same tape
every night, and if the backup takes several hours to complete, the hours
calculation is pretty important.

Yes it does bu you should read documentation about recycling. When Bacula
cannot find a backup ready volume (volstatus = Append or Recycle/Purge)
then it perform a recycle procedure.

Re: [Bacula-users] Retention period - last written date, and time?

[Gi Dot]

The one day retention period was just an example. Plus, the 'use volume
once' directive works if I have only one job to run daily, which is not the
case. Say if I need bacula to recycle the same volume on weekend, I'd
resort to using "volume use duration" directive, with retention period just
a few hours extra.

Create pools distinct with retention expected and create 2 Jobs for  this
client

You can set  the Job and File retention with the higher retention as you
expect, because when the volume is recycled it will prune Jobs and Files
from Catalog, for this you have to set in the Pool resource "Auto prune =
yes"
