Backup Devices

I'm looking to upgrade from an AIT tape drive, any advice on what I should be looking for, I don't want to have to upgrade again for a few years so i'm looking at something with the capability of backing upto a max of 500Gb.

Budget £3k (possibly more if needed)

Search on the forum as many people have their on views on this.

Dos_Box and I have a Tandberg LTO2 Autoloader - you'll easily get 500GB on there. They cost about £2500 which will leave you with money for decent backup software - I quite like Retrospect (again Dos_Box and I both use it).

Thanks Ric.
