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)
