I thought I'd try it this way - having one job for the incrementals, and one
job for the virtualfulls (using bacula-5.0.1 and disk volumes).
Schedule { (incr schedule) }
Schedule { (virtualfull schedule) }
Pool { (full pool) }
Pool { (incr pool) }
Client { (client) }
FileSet { (fileset) }
Storage {
Name = "Disk 1"
...
Device = "Disk 1.0"
Device = "Disk 1.1"
Device = "Disk 1.2"
...
Maximum Concurrent Jobs = 20
}
Job {
Name = "VirtualJob"
Type = Backup
Level = VirtualFull
Schedule = "(virtualfull schedule)"
Pool = "(incr pool)"
Priority = 10
Client = "client"
FileSet = "fileset"
Full Backup Pool = "(full pool)"
Incremental Backup Pool = "(incr pool)"
Maximum Concurrent Jobs = 1
Storage = "(storage)"
Accurate = yes
}
Job {
Name = "RealJob"
Type = Backup
Level = Incremental
Schedule = "(incr schedule)"
Pool = "(incr pool)"
Priority = 10
Client = "client"
FileSet = "fileset"
Full Backup Pool = "(full pool)"
Incremental Backup Pool = "(incr pool)"
Maximum Concurrent Jobs = 1
Storage = "(storage)"
Accurate = yes
}
I had already run some Incrementals with 'RealJob' (the first got upgraded to
a Full).
I then started 'VirtualJob', and a few seconds later, 'RealJob'.
'RealJob' completed OK.
But 'VirtualJob' said:
Warning: acquire.c:265 Read acquire: label.c:239 Could not reserve volume
backup-0193 on "Disk 1.2" (/write/mnt/Disk 1/var/lib/bacula/volumes)
It looks like backup-0193 was being read by 'RealJob'.
'VirtualJob' then started asking the operator to mount backup-0193, which
I couldn't help it with, no matter how much I typed 'mount' and 'unmount' into
bconsole (but that's another problem for another day).
The question is:
Why does the Incremental job need to read (and reserve) the volume?
