I have been learning and trying to understand how Bacula works for the last
two weeks. Here is my situation. For simplicity purpose, lets assume I
have two servers (I actually have 37). My boss whats to have full backups
to tape every Sunday, and incremental backups Monday through Friday to file.
Currently I setup each machine with their individual files and included them
in the bacula-dir.conf file as "@/etc/bacula/hosts/machine1". See link for
a sample of the settings for http://www.nabble.com/file/7952/machine1
machine1 machine1
I specified three pools, Full, Incremental and Diff. I also specified a job
for each day of the week, machine1_mon, machine1_tue, etc. The storage was
doe the same way, MonStorage_machine1, TueStorage_machine1. The storage
device was also separated on a per machine basis, i.e. MonBackup_machine1,
TueBackup_machine1. The reason for this was that the Archive Device went to
individual folders, one for Monday, one for Tuesday and so forth. A sample
of this setting is as follows:
Device {
Name = MonBackup_Machine1
Media Type = File
Archive Device = /var/spool/backup/mon
LabelMedia = yes; # lets
Bacula label unlabeled media
Random Access = Yes;
RemovableMedia = no;
AlwaysOpen = no;
}
One of the problems I have noticed is that when there is no Full backup and
I want to do an incremental backup, bacula will force a full backup. That
would be ok because I thought if I did a full backup this Tuesday and then
next Tuesday I believe I would get an incremental backup but that did not
happen. I am trying to understand why an incremental was not done.
What would be the best method of configuring bacula to do a full backup
every Sunday and then incrementals Mon through Fri. I am still confused
about the usage of volumes. Can someone explain this in better detail? If
"Maximum Volume Jobs = 1" mean one job per volume and therefore an
incremental will never happen? What should it be set to?
These are only a few of the questions I have.
TIA
Mike
