Re: [Bacula-users] Forcing baccula to purge/recycle a tape instead of appending?!
Hi!
Yes, I know.
But I have 6 clients. And for each client I wrote two jobs:
1) Backup to file (pool: filepool)
2) Backup to tape (pool: monthlytape)
The tape backup is triggered on every first saturday of a month.
The schedule and the job looks like this (from memory):
===
Schedule {
Name = "MonthlyBackupToTape"
Run = Level=Full Pool=MonthlyTape 1st sat at 2:00
}
Job {
Name = "Client1-ToTape"
Type = Backup
Level = Full
Client = dns
FileSet="fs-dns"
Storage = LTO4
Pool = MonthlyBackupToTape
Schedule = "BackupToTape"
}
===
But maybe sometimes a backup goes wrong and I want to re-start the
tape backup manually for the specific client. So I'd need jobs like
client1-toFile
client1-toTape-Jan
client1-toTape-Feb
client1-toTape-Mar
client1-toTape-Apr
client1-toTape-Mai
[...]
But to resume the thread's title... can I switch from my "monthytape"
pool (12 tapes / one pool) to the new "1 tape / one pool" pool without
loosing the backup information of the last 11 tapes?

Other issues aside, you do realise that tape reliability claims are based on the assumption you write the tape once, put it in (controlled enviroment) storage and never take it out again, right? I.e. if you plan on overwriting the same tape more than one or two times, you're better off backing up to hard drives. Dima -- Comprehensive Server Monitoring with Site24x7.

Re: [Bacula-users] Forcing baccula to purge/recycle a tape instead of appending?!
One more thing that is worth mentioning...
If you truly want the monthly tapes to only ever be used for that
particular month, you may wish to consider creating a pool for each
month instead. Then in your Schedule you can specify the specific pool
for that month:
Schedule {
Name = MonthlyBackups
Run = Level=Full Pool=January jan 1 at 00:00
Run = Level=Full Pool=February feb 1 at 00:00
Run = Level=Full Pool=December dec 1 at 00:00
}
If in the future you need multiple tapes for a month, this approach
would allow you to have multiple tapes in each month's pool as well.

Also remember that changing these limits in bacula-dir.conf does not apply the change to existing volumes. You need to use bconsole to "update pool from resource" then "update all volumes in pool" to apply the config changes to existing volumes. John -- Comprehensive Server Monitoring with Site24x7.

Re: [Bacula-users] Forcing baccula to purge/recycle a tape instead of appending?!
There are a couple of things you can do in combination to get the result
you want...
First off, in your pool set a 'volume use duration' - this will restrict
how long a time span of data can exist on a tape. For instance in your
case you could set the volume use duration to 32 days, this would tell
Bacula not to append any data to a tape 32 days after the first data was
written to it. The tape will get a status of 'USED' rather than
'APPEND' once that time period passes. Regardless of what happens with
the expiry / purge jobs this will prevent the scenario you are
describing from ever happening - Bacula would instead complain that it
could not find a tape if one wasn't available, it would not append data
to an 'old' tape until the jobs on it were purged.
Secondly yes, set the volume retention lower. Bacula will not purge a
tape unless it needs to so it won't automatically purge data when it
hits the volume retention date - even if you did need data off of a tape
that was 11 months and 28 days old but Bacula hadn't needed the tape for
writing yet, the data would still be there so you won't be loosing anything.

[Bacula-users] Forcing baccula to purge/recycle a tape instead of appending?!
Hi!
I have a problem with my tape pool configuration.
I want to use exactly 12 LTO tapes (one tape per month).
After 12 month the oldest tape shall be reused without appending new data.
But bacula seems to ignore my recycle and purge configuration (see below).
After one year I reuse the old tape and bacula appends the new data to it.
Then, after the second year has passed, the data is still appended to
the tape!
Now I have the problem that my september tape ran out of free space and
I was
asked to insert the august tape... a few MB later that tape was full
also and
bacula asked for the july tape :/ :/
So I manually purged the september tape and restarted all related backup
jobs.
How can I configure bacula to purge the oldest tape instead of appending
to it
for more than two years?
My pool configuration for the tape looks like this:
# ==
Pool {
Name = MonthlyTape
Use Volume Once = no
Pool Type = Backup
AutoPrune = yes
Recycle Current Volume = yes
Volume Retention = 12 month
Recycle = yes
}
# ==
Would it make sense to set the retention time to "11 month 1 days"?
Thank you very much!!
