To coincide with moving our office to new premises I'm having to upgrade our file server at work. We currently work from a single shared 40Gb drive accessible from all our machines as 'O Drive'. Due to various factors I've had to increase O Drive to two 200Gb IDE HDs in a RAID 1 config. Moving offices has been penciled in as the ideal time to do the hardware upgrade.
Anywho, the point of this post is to ask for some ideas on suitable backup solutions for 50-150Gb of data. Prior to the increase in drive space a backup of changed files was made every 15 minutes over our network to another 40Gb HD (Backup A). Every hour a complete backup was made and stored on yet another 40Gb HD (Backup B). At the end of the day backup B was/is taken home and replaced with Backup C (Yes, another 40Gb drive) so we always have a 24hr backup/rollback off-site.
I'd better point out that we're not modifying/creating 10s of Gb of data per day - we keep all our projects (past and current) on O drive and usually have about 4-6Gb of files in each current project. O Drive is also used to store disk images of all our CD masters (in addition to CD masters kept at a number of off-site locations), we have roughly 60Gb of disk images.
Now with the move to a 200Gb drive for the design staff to work from, should we be continuing with the same backup process as before (but with 3x 200Gb drives for backups) or is there a better alternative? I didn't set the original system up and the guy who did is long gone - so I'm more than willing to implement a new routine if it's going to be more efficient / cost effective.
So, Suggestions? Limiting factors are really only cost and my only technical ability. I'm willing to spend the equivalent of buying 4x 200Gb (decent IDE ones), a.k.a £400/$700, on a solution, plus any software costs. After discussions with the rest of the staff we've ruled out tape drives. The file server currently runs a vanilla install of Windows 2000, but our 'technician' is mumbling things about putting XP on there. A copy of 2003 server is lying around in the office somewhere. Clients use a mix of 2k and XP. Anyone who suggests Macs as a solution will be shot.
