I have a system which I'm backing up and have it set up for "Always
Incremental" backups. I ran a Full job by hand and have schedules for
Differentials and Incrementals, and once a week Bacula will roll up and
Incr and Diff jobs greater than 30 days along with the existing Full into a
rolling Full backup. That all seems to be working fine. What happens,
occasionally, is Bacula will promote an Incremental backup to a Full
Backup. Not to a VirtualFull, an actual Full. I would assume that
something which might cause an Incr to be promoted to Full would be a
change in the FileSet. Like I had /data in my includes and /data/temp in
my excludes, and I modified the file to add /data/scratch to the excludes.
Is this assumption correct?
What I'm not sure about, however, are any other changes which might trigger
elevation.
- Permissions change on the fileset.conf file?
- Datestamp on the fileset.conf file?
- other changes to the file unrelated to the fileset, like maybe adding a
comment line, or removing a comment line?
Any thoughts on this, or does someone absolutely have a known list of
things which will promote an Incr to Full, or Diff to Full???
Thanks,
-John
