You guys are certainly correct in that the backup policy is more important than the actual software. It's something I'm working on at the moment (amongst a ton of other things) - how often to do full backups (weekly at the moment), whether to do nightly incremential or differential backups, and so on. I'll trawl through some of the previous threads and see how others have their backups set up.
We're going to buy some Symantec Corp AV licenses soon and the donation rules state - I think - that we can only order from Symantec once per fiscal year. So I kind of need to decide now whether we're likely to need to use Backup Exec in the oncoming 12 months.
As for the email set up: currently each user is supposed to copy their own .pst file(s) on their machine to a specific folder on a network drive, and this folder gets included in the backups. Not ideal, but that's also something I need to look at sometime. And yeah, this really should be an automated process. So the B.E. remote agent is able to copy specified files across to the server in order to get included in the backups? That's great, and as you say would also be a good way of backing up other local data.
Thanks a lot for the input guys. This is a great forum :)
