Hello Guys,

I have archival backups going back 10 years without any problems.
If you want to be able to restore any single file from the backup, then you
need to explicitly configure File Retention and Job Retention in the Client
resource, because they default to 60 and 180 days respectively. I've set them
both to 50 years.
You also need to set the Volume Retention in the pool (which defaults to 1
year).
After changing any of these, update the db and volumes using the bconsole
update command.
Thanks Martin, these points are essential. When a Volume has no Job Record
associated, it can be purged, and it's not what you are looking for.
In general, I recommend to manage retention only at one place. Bacula
is very flexible, and you have probably 10 different directives to control
the retention in many scenarios.
For example, set Client / File Retention and Job Retention to 50 years
and set the Volume Retention to what you want.
I would never prune Job Records if you can, File records are nice in
general, but you might end up with a very large catalog.
It is possible also to disable Autopruning in different places,
doing so, you control exactly when Bacula will prune records.
Keep us informed, Hope it helps!

Thanx for the response, appreciate it
As to media, plan is to put it on disk, with some sort of raid(1, 5, 6)
to ensure safety/integrity, that is where the files are right now
as to the amount of data, it is not that huge, weekly full backups is
around 50 GB, and it lends it self well to compression, and data does
not change that much so incre. backups should be small, my concern is
mainly the database(using postgresql) and whether Bacula can handle such
retention times of say 3560+ days
I have seen reten times of one year but that is about it, if anyone have
experience of handling longer retention times and care to share their
experiences or config files for the jobs, I would be grateful

hello everyone
I need to set up backups for a set of files that need to be saved and
be possible to access for a very long time(approx. 10 years, for
compliance reasons), is this possible in Bacula or even advisable??
Or do we need to solve this some other way
The first problem you have is finding media that is guaranteed to last
for 10+ years.
Tape is generally considered the best for this, but... YMMV if you
don't store it correctly.
Another option is long-term optical disk, which is not the same as DVD
or Blu-Ray.
Talk to the suppliers of archival services in your country for
information on what is available and sensible.
The second problem is storage for the database. If you have millions
of files that change frequently you will need a lot of space for the
database.
Non-Bacula solution: Back when I was at SGI we offered HFS -
Hierarchical File System - for people who had this sort of problem.
And very, very deep pockets.
I don't know if Rackable kept it alive when they purchased SGI, maybe
talk to them?
Cheers,
Gary B-)
