As with every other backup system, Bacula should eventually notice the
gap in the incrementals and perform a full backup at the 23rd. I havn't
testet that scenario and would not dare do so in a production
environment. I would, depending on the activity of the client, also
recommend differential backups, say once a week. Incrementals always
refer to the last incremental, differentials refer to the last full or
differential backup. Give it a differential job, say on the 14th (halb a
month) and you're good to go.

I want to have the capacity to watch a system state for 21 days and no

I'm having a hard time to understand, what you want. If you run a full
backup every 1st of the month and keep running incremental backups you
will run into trouble after the 21st day of incremental backups. Bacula
will notice the gap and run a new full backup. Like I said, I'd resort
to differential jobs...

Sorry for my english

Forgot all that I say.

I want the capability to select files no more than 21 days of one job, 
and I want that, that volumes be recycled after 21 days(max use time (23 
hours))

Is that possible?

Thanks!!

Here my configuration of pools and shecules
Pool {
  Name = pool_incr
  Pool Type = Backup
  Recycle = yes
  AutoPrune = yes
  Volume Retention = 25 days
  Label Format = "Incr-"
  Volume Use Duration = 23 hours
  Maximum Volume Bytes = 4G
}

Pool {
  Name = pool_full
  Pool Type = Backup
  Recycle = yes
  AutoPrune = yes
  Volume Retention = 2 months
  Label Format = "Full-"
  Use Volume Once = yes
  Maximum Volume Bytes = 5G
}

Schedule {
  Name = "20:00-00:00-1"
  Run = Level = Incremental mon-sat at 20:00
  Run = Level = Full 1st sun at 00:00
}

My objetive is to have memory of a server only (and always) for 21 days, 
and full snapshots for 2 months. (1st January, 1st February for example, 
and February2-22 incrementals)

What happend 23rd of February?

Is differential backup my solution?

Do you understand my explication? (sorry for my english)

If there are no appendable tapes in the  pool_incr then bacula will
find a tape in that pool and recycle it.

The following link describes the procedure bacula will use to
determine what volume it will pick:
http://bacula.org/en/rel-manual/Automatic_Volume_Recycling.html#SECTION002530000000000000000

So if the volume that was purged was the same volume that had been
used for the previous 21 days bacula should upgrade that incremental
to a full on the 23rd. With that said I have seen a recent thread
where under some circumstances bacula does not do that and that it
will continue with an incremental  but since it removed the previous
incrementals you can not restore.

I am a little confused at your reason for only holding 21 days of
incrementals max. I assume you have a limited storage.

How is the configuration with differential backups? one differential at 
the middle of the week?

explain me all that you can

thanks

Put something like that into your scheduler configuration. this will run
an incremental backup every 2nd to 5th Sunday of the month at 11am.

Run = Level=Differential 2nd-5th sun at 11:00

Hope this helps.
