If i set Maximum Volume Bytes = 10GB then it uses the full 10GB at the
very first run as full-backup. But the increments later get always
written to new Volume Files. E.g.
Volume-0001: 10GB (from full run)
Volume-0002: 10GB (from full run)
Volume-0003: 10GB (from full run)
Volume-0004: 126MB (from full run)
Volume-0004: 7MB (incremental run later on...)
I would have expected, that it would ALWAYS append to my volume until
it reaches its "Maximum Volume Bytes" (here 10GB) limit.
Again, here is my Pool Definition:
Pool {
Name = File
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 14 days
Maximum Volume Bytes = 10GB
Maximum Volumes = 500
Label Format = "Volume-"
}
Thanks a lot,
Mario
