Hello fellow Bacula users,
I am using Bacula to connect to servers remotely (in a different DC) and backup.
Due to speed constraints and no bogging the office network down during the day,
I dont see it is feasible to perform a full backup of our 4 servers at the same
time, so instead we can split out the full backups so each week one server has
a full backup, in rotation.
Load spreading of full backup transfers
If we had 4 servers, we want to perform a full backup in rotation as follows:
1. myhost1 => 1st of every month full, incremental all others.
2. myhost2 => 8th of every month full, incremental all others.
3. myhost3 => 15th of every month full, incremental all others.
4. myhost4 => 22nd of every month full, incremental all others.
Retention
Given any particular date, we want to keep a full backup, plus the last full
backup before that. All incremental from now to the most recent full backup
should be kept.
Full and Incremental in seperate pools
I have two storage pools, one for incremental and one for full, how can I tell
Bacula to use pool-full if a incremental snapshot cannot find a previous full,
and how do I put full on storage1 and incremental on storage2 (which is the
same storage daemon, but different drives)?
Scalability
Potentially could have more servers, if i wanted to rotate them over Saturdays
and Sundays (giving up to 8 schedules per month on days [1,2], [8,9], [15,16],
[22,23]) - is there any easier way to make this scale or would I just keep
adding schedules and job-defs?
I have gone as far as I can with my config below (other non-relevant parts
removed) and would apprecite an experienced eye to point me in the right
direction.
My relevant config is below and need help confirm/tweaking as needed, thanks in
advance.
