Re: [Bacula-users] Bacula maintenance : Clean Data

Hello Radoslaw

Thank you for your answer.

I have to more questions because I discover a new command in Bconsole : "Prune"

To clean I use set the retention file at 0 days then I log in to Bconsole and "prune client=my_client" after that I select "Files" and finaly 'yes'. Do this action trucate all data associate to my_client ? I've got 115 critical server to backup, I don't want to mess this up :)

Hello,

2011/6/6 Buschini Edouard <moon AT ijaal DOT net>

But today we have a big problem, we didn't anticipate a growing like that, on our FS we are at 97% of space used. It's very problematic. And since 1 week I'm working on free more space but it's very complicated with Bacula.

If you are doing a backup to disk (filesystem) then you can simply delete oldest/not required volume in bacula and rm it from filesystem.

I would, but datas from every Client are in the volume, so I cannot simply delete the volume, therefor we have a rotate of 4Go volumes.

I've search every where but I didn't find any exploitable answers so I'm asking here.
Do you have a prefered method to do the following task :

Purge then Prune (I'm on auto-prune) then Truncate a volume for a client ?

There are "best practice" for optimal volume management when you use filesystem based volumes:
- use 1 job / volume

That is a good Idea ! I noted it :)

- use action on purge = truncate

Already activated.

- adjust your retention policy and backup schedule (more Incr, less Full)

That's why we have to rethink all the stategy.

- use compression on client if you have enough computing power

We have, around 80-90% data reduction.

- use filesystem level compression on storage daemon

I don't know about it ? What's that ?

regards

Radoslaw
