I don't see alot here about backups and backup schemes. In fact in my searching I have found much about backup schemes on the web.
In my situation we are a small shop (20 machines, 15 Users, in a peer network), however we have alot of data 400+Gb. It is somewhat critical to have at least a differential backup everynight for us. As for servers, I have a mail server and 2 file "servers" (Server 1 is a FreeNAS server and the Server 2 is an XP machine). The XP Machine does a full backup on Sunday, and differentials on every other day, each of these goes to a new folder by day name i.e. Sunday, Monday...etc. Each Sunday the backups start getting overwritten, Every other week I manually pull the full backup and save it. The Email server does its own backups to Server 1 and cycles them. Server 1 (FreeNAS) is new to me, so I don't have a real backup running yet.
The questions is, what are you all doing for backups? How do you cycle your backups. What is your reasoning for this?
I personally am not a fan of tapes, and I have enough HDD space to maintain redundant backups on site. Does anyone use FreeNAS? What backup software do people use? Does your software cycles the backups?
One last note, I am not a fulltime IT guy(I used to do it fulltime), though I am the only IT this office has.
