Backups and multiple servers setup

[fconil]

Hi,

I have a multiple servers setup (ldap, MTA, mbox). Backups are running as set by default on the servers. (full weekly every week, and incremental daily on the mailbox server).

I also have an exact copy (VMs being duplicated on another server) of my 3 servers.

My questions are as follow:
Can I export the /backup folder somewhere else "just in case" ?
Can I restore this backup on another server, provided the configuration/version is the same?
In which order should I restore the backups if need be, or can I just do it on the mailbox server?

Thanks for your answers.

sure. in fact you could have /backup as a nfs share, although backing up directly to a nfs share can be pretty slow. i have my setup so that my full backup runs on friday and backs up to a local drive, then a script moves that backup to a nfs share.

yeah

ldap should be first, after that I don't think it really matters. I don't think you can easily condense a multiserver backup into a single server restore if thats what you're thinking. the upgrade path for multiserver says do ldap -> mta -> mailbox so you might want to follow that.
