#chkconfig bacula-fd on

Login to webmin https://you_domain_name:10000 and add config to bacula backup system. Now the bacula system is ready to go.

Volume recycling

To recycle volumes in pool, create pool with desired volume retention period for ex 2 weeks.

Create new volume in same pool with different volume name ex, myvol2.

Once the volume retention period is over, Bacula delete the old volume and try to use new volume created above in this case it is myvol2. If no volumes are present after retention period, Bacula uses the current volume to append data and create new without recycling old volumes. This leads to more storage occupied by the volumes that are not in use.

Sample monthly backup job

Job {

  Name = mybackup

  Type = Backup

  Client = bacula-fd

  FileSet = full

  Schedule = Monthly

  Storage = File

  Messages = Standard

  Pool = Default

  Full Backup Pool = Full

  Incremental Backup Pool = INCR

  Differential Backup Pool = Diff

  Level = Full

}

Schedule {

  Name = Monthly

  Run = Level=Full Pool=Full on 1 at 18:00

  Run = Level=Differential Pool=Diff sun at 20:05

  Run = Level=Incremental Pool=INCR on 2-31 at 20:10

}

Pool {

  Name = Full

  Pool Type = Backup

  Volume Retention = 3 months

  Recycle = yes

  AutoPrune = yes

  LabelFormat = full-

  Maximum Volume Jobs = 1

}

Pool {

  Name = INCR

  Pool Type = Backup

  Volume Retention = 2 months

  Recycle = yes

  AutoPrune = yes

  LabelFormat = incr-

  Maximum Volume Jobs = 1

}

Pool {

  Name = Diff

  Pool Type = Backup

  Volume Retention = 40 days

  Recycle = yes

  AutoPrune = yes

  LabelFormat = diff-

  Maximum Volume Jobs = 1

}
