Hello,
I'm currently running Bacula 9.6.7 on Ubuntu 20.04 and have been for
several months testing it out. We're looking to implement Bacula as a
replacement to our current backup system agency wide but before I can
present the solution, I have to present a working example.
In short, all that I'm trying to accomplish for this example is backup
to two drives that are in rotation. For example, the first drive will be
mounted for 1 month before being swapped with the alternate drive for a
month. After the second drive has been in for 1 month, we'll swap back
to the first drive. Additionally, all of the client jobs are marked as
incremental. I see that the first time backups are done on the first
drive the job is promoted to full backup and then I received incremental
backups for each client after that. However, I need to be able to define
the second drive. Then when the swap is made from drive 1 to drive 2,
each of the jobs will create a full backup and then become incremental
after this. Additionally it after the swap back to drive 1, the first
jobs would still be incremental against where we were at that point in time.
The description above is our current working scenario using Retrospect
just scaled way down for testing purposes. For reference, we typically
backup around 100ish clients and have three sets of drives that are in
rotation: onsite online set, an onsite offline set, and an offsite sets.
These sets are rotated each week.
Bacula has performed excellent with everything I have thrown at it in
terms of tailor jobs, scheduling, etc. (leaps and bounds better than
Retrospect in my opinion) backing up to a single drive. However, I've
really hit a wall trying to setup this basic scenario with two drives in
rotation.
Does anyone has a basic example for something like this?
I've spent close to a month researching and trying things prior to send
this email, but I just can't seem to figure it out. I've spent a great
deal of time trying to work out an autochanger scenario, but I'm feeling
as though my scenario may just come down to defining the two drives and
working out a scheduling so that one month they go to one drive, the
next month they go to the other drive, the next month the original
drive, etc.
I'm really hoping there is a more elegant solution possible utilizing an
autochanger (if needed) and letting Bacula handle the leg work versus
having to do it all via scheduling. I don't feel as though management
will accept my proposal if it's done via scheduling and requires a bunch
of hand holding.
Retrospect has served us well for many years however, in recent years
stability has been an issue and we've had more and more issues with
Windows clients. Bacula on the other hand always seems to work
flawlessly even on the more common trouble client! I'm really hoping we
can make the switch and of course we will be a paying customer.
Thank you to whom ever takes the time to read this and help out!
Joey
