backup solution 4576

My suggestions would include:

BRU is what I use myself. BakBone is a product I've just recently heard about, so I don't know much. Arkeia I evaluated before choosing BRU. Arkeia was a lot more expensive and it's GUI wasn't terribly intuitive to me.

There's also the big boys from Veritas and Legato but since your needs are fairly small (10 GB per day and 50 clients isn't a lot) they may be more expensive than what you're willing to spend.

Why an LTO-2 library for just 10GB per day? You can do that much data in under an hour with a much, much cheaper backup system. (Maybe you need the capacity-performance of LT0-2 for weekly full backups or something? You don't mention how much data and how large a window you have for full backups, nor how often you intend to do them. But from what you have said, an LTO-2 library sounds like more money than you need to spend.)

In order for the backup to of any use at all, removable media is a *must*. So is having multiple generations of backup available. If your lone backup is being over-written with a newer backup at the time of a catastrophic failure, you're sunk. It doesn't matter if you're using tape or removable hard drives, you need more than one set of backup media. Likewise, you need to be able to physically move your backup off site (think flooding, fire, etc.).

Personally, I find the compelling reasons to use tape are the easy ability to have multiple sets of backup media and its portability.
