Hey guys,
Thanks for the replies and good advice. The reason I thought of this backup
plan is because what I need to back up are multiple dynamic file systems from
abut 20 servers. These file systems contain data that is always changing since
they contain various dynamic application files. I do not need to have backups
that are old; in case of a disaster, I need to be able to bring back the data
that was lost during the past hour at most, so that the people working with the
applications only lose 1 hour of work in the worst case scenario. I have this
set up and running pretty well on 2 hosts so far.
The only problem is the filesystem that I back up has 91 gigs, and the backup
keeps getting bigger and bigger with all the differential jobs. So far the max
vol size is set to 300GB, and with the backups running all weekend it now
created a second volume for the same job since it reached its max size on the
first volume. It's why I need to find out how to make Bacula remove older
differential jobs from the first volume. As far as I know, during a restore on
a backup that uses differential backups, only the last differential backup
(which should contain all other changes made to the backed up filesystem in the
previous diff jobs) and the full backup should be required.
Here is my setup. (If you guys have a better ideea on how I should set this up
considering my needs please feel free to advise)
Thanks a lot for the help !

reasons)

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
