I'm looking for suggestions on making/providing nas storage/network backup for my site... Currently my options are to use an old dell server and rig it with decent hard-drives in raid or some similar file replication setup, install extra hard-drives in my new "not yet purchased" server and use it for shared storage + backups + use a 3rd party nas system or the before mentioned old server for replication of the backups.
So... I'm looking for suggestions for backup software "cheap or free," also I'm looking for information on how best to protect my backups from failure/localized disaster and file degradation/corruption. If anyone can comment on good software for replication across multiple drives that trumps raid, I'd love to hear about that too.
Plus on whether I can or should attempt to do it with either of the above mentioned options, thanks for your time.
