which backup system for a farm of 150 Servers
 
Hi,

currently im doing the backups with a nightly bash script that dumps and rsyncs from all server to a backup machine and than writes to a tape.

I was looking at bacula and some other tools.
Which one would fit for thies size?
Most of the Backups are mysqldumps.
We have a superloader3 with a DLT-S4 Tape and we are som close to the
800GB that sometimes I get IO/Errors when writing one of our folder to tape.

What System would you prefer?



cheers.

I have used amanda with success. Admittedly not on such a large job, or to DLT-S4 tapes either, but according to the amanda docs, this would not prove difficult to implement.

Can you not double the capacity of the DTL-S4 by switching on hardware compression?

Clearly Amanda can do the job. See http://blogs.umass.edu/choogend/2007...-about-amanda/.

You mention that most of your backups are MySQL dumps. Then you should look at Zmanda Recovery Manager (ZRM) for MySQL -- http://www.zmanda.com/backup-mysql.html. It is by far the best system available for managing MySQL backups. You can implement it on the backup server with the backups to disk on that server and then use Amanda to orchestrate everything to tape.

You can get opensource for both of those products. Just download the community edition. You can also get enterprise support, if that's what you need.

I want to advice bacula to you.
It is very mature and has all normal/advanced features you want.

You can even do bare-metal restores with it.

and as said above zrm is indeed a very good way of backing up mysql
