Backup Central

I'm new to the field of advanced backup systems. I'm kind of the self-appointed backup guy in our company of 3 people.

Our current setup (which tons better than the previous one!!) consists of a 1TB 4 disk mirrored RAID drive. We use this networked drive as our "working drive" where all client files we access are stored as we work on them (it never gets much more than 200GB on it).
After a job is completed, it get sent to our servers' internal drive (750GB) to be backed up by Carbonite.
Once Carbonite backup is confirmed (a week or so) we then delete the files located on our 1TB "working drive" since we do not need or want lots of files cluttering our working drive.
All this is done by me, and takes a good chunk out of my time (especially if I havn't done it for ages, like right now)

I am hoping to move it towards a more automated and scalable system very soon.
Something along the lines of;
1. Working Drive stays as is, we use it for current projects and rely on it's RAID mirror to protect us from drive failure.
2. Files are backed up daily to a large storage box of at least 3TB (local).
3. Files from large storage box are backed up daily to an offsite FTP server (old pc with lots of drives that we'll build) located at one of our houses.
4. After a certain amount of time (1 month?) files on our Working Drive are deleted - making the assumption that we aren't using them anymore.

All of this would be automated hopefully.
My main question is whether or not there is some backup software that can automate this (including deleting older files)? I can find backup software that seems to do the backup part, but not the deleting....

thanks for any input.

Post the operating system(s) involved here... that may spark a response.

If this is all Windows stuff, products at http://www.acronis.com/ might do the job... there are lots of Windows-based backup utilities out there.

Amanda is a free open-source backup product... not sure if it could run as server on Windows system though. There is a discussion forum at this site for Amanda.

Also: There are a number of Carbonite-like services; see the table at http://en.wikipedia.org/wiki/List_of_online_backup_services

I know the service called CrashPlan has a backup client that will let you store data from a system to their servers, or to extra space on a system at a friend's house!

The software will be running on Windows. Sorry should have mentioned that.
Crashplan sounds interesting....

Any ideas on the auto-delete option? Even a standalone program that will run all the time and delete every now and then.

Crashplan looks great, love the option to backup locally! We might seriously look into that.
