Hello
I'm trying to implement deduplication in my bacula installation but I didn't
understand how does it fit into my installation. The bacula documentation about
base jobs are not very usable (my opinion). Further I spent some hours in
google but I didn't find any helpful hint.
My problem:
I have 2 servers called asterix and obelix. I want to backup both servers with
bacula. Asterix is the primary server and obelix is rsync-mirror of asterix. So
obelix should be nearly identical with asterix and the backup of obelix should
be based on asterix. The pool resides on disk.
Job Definitions:
Job {
Name = "asterix-Backup_BUERO"
Client = asterix
Schedule = "Sched_1st-sun-Full_sun-Diff_daily-Incr"
JobDefs = "JobDef_BUERO"
}
Job {
Name = "obelix-Backup_BUERO"
Client = obelix
Schedule = "Sched_2nd-sun-Full_sun-Diff_daily-Incr"
JobDefs = "JobDef_BUERO"
Schedule Definitions:
Schedule {
Name = "Sched_1st-sun-Full_sun-Diff_daily-Incr"
Run = Level=Full 1st sun at 01:00
Run = Level=Differential 2nd-5th sun at 01:00
Run = Level=Incremental mon-sat at 01:00
}
Schedule {
Name = "Sched_2nd-sun-Full_sun-Diff_daily-Incr"
Run = Level=Full 2nd sun at 02:00
Run = Level=Differential 3rd-5th sun at 02:00
Run = Level=Differential 1st sun at 02:00
Run = Level=Incremental mon-sat at 02:00
As you see in the schedules, asterix is doing a full backup once a month, a
differential backup each sunday and a daily incremental backup. obelix is doing
the same with 1 week offset.
If I declare asterix as Level=Base what happens with differential and
incremental backup of asterix.
1. Are these type of backups also a base backup?
2. Which backup (full/diff/incr) is base for obelix? All jobs have the same
name.
3. Or do I need an extra job with run a full backup as a "base-only-job" on
asterix and have a reference from both servers to them?
3.1. If yes, what happens if this "base-only-job" is replaced by a new one? Is
the old "base-only-job" still available as long as all references are gone?
I appreciate any info.
regards robi
