Hey guys,
I'm currently looking into implementing a backup-cycle that takes daily incrementals, weekly differentials and monthly fulls (actually VirtualFulls in my case). The goal is to be able to restore a file in its daily state for a 'sliding window' of roughly one month.
My other goal is to recycle volumes as quickly as possible after they expire (to save diskspace and to have a somewhat constant count of volumes).
My main question is if the retention periods I set are sane for the goals I have in mind or if there are other catches I'm not aware of.
My schedule looks like:
Schedule {
Name = "WeeklyCycle"
Run = VirtualFull 1st sun at 20:00
Run = Differential 2nd-5th sun at 20:00
Run = Incremental daily at 23:05
}
Pool {
Name = {{ hostname }}-Full
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 34 days Maximum Volume Bytes = 50G
LabelFormat = "{{ hostname }}-Full-"
Maximum Volume Jobs = 1
Action On Purge = Truncate
Storage = {{ storage_node }}
Next Pool = "{{ hostname }}-Virt"
}
Pool {
Name = {{ hostname }}-Incr
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 8 days Maximum Volume Bytes = 50G
LabelFormat = "{{ hostname }}-Incr-"
Maximum Volume Jobs = 1
Action On Purge = Truncate
}
Pool {
Name = {{ hostname }}-Diff
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 9 days Maximum Volume Bytes = 50G
LabelFormat = "{{ hostname }}-Diff-"
Maximum Volume Jobs = 1
Action On Purge = Truncate
}
Thanks for your help!
