I would like to apply some job/file retention strategy but I don't know
how.
Here is what I would like:
- Full backup on the first Sunday of the month, kept in a single copy
- Diff backup on the 3rd and 5th Sundays of the month, kept in a single
copy
- Inc backup every other day, kept just the time needed compared to
Full and Diff.
(I have no problem with the schedule. It already works like that. No
need to spend time on it.)
Here is what I had so far, which works for volume renewal, but I am not
sure that I will not lose files along the way:
Pool {
Name = Full-Medion
Label Format = medion-full-
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 40 days
Maximum Volume Jobs = 1
Maximum Volumes = 2
}
Pool {
Name = Diff-Medion
Label Format = medion-diff-
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 13 days
Maximum Volume Jobs = 1
Maximum Volumes = 2
}
Pool {
Name = Inc-Medion
Label Format = medion-inc-
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 5 days
Maximum Volume Jobs = 6
Maximum Volumes = 2
}
But now, due to lack of space, I would like to reduce the retention to
the bare minimum as I explained above.
I thought about doing:
Pool {
Name = Full-Medion
Label Format = medion-full-
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 1 month
Maximum Volume Jobs = 1
Maximum Volumes = 1
}
Pool {
Name = Diff-Medion
Label Format = medion-diff-
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 15 days
Maximum Volume Jobs = 1
Maximum Volumes = 1
}
Pool {
Name = Inc-Medion
Label Format = medion-inc-
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 14 days
Maximum Volume Jobs = 6
Maximum Volumes = 2
}
but I feel like it can't work on single volumes. Until now, I wanted a
single volume for each Full and Diff, and a volume per week for the
Inc. But this notion of volume seems ultimately blocking to me.
Shouldn't I put everything in a single volume to achieve what I want?
Should I make a single pull, without limiting the number of jobs, with:
Volume Retention = 1 month
Maximum Volumes = 1
?
NB: keep it simple please, because I don't master the language or
bacula...
