[ALUG] WTD: Recommendations for External Tape Drive to backup SUSE server

Hi, As per subject, really. Someone has asked me for any recommendations I can find for external tape drives which could be used to backup the contents of a SUSE Linux Enterprise Server or an openSUSE server. I imagine it just requires something which has usable Linux drivers but as I've never had to do anything in this area, I thought I'd throw it out there and see whether anyone else has ... and could recommend a brand or model. Thanks, Peter.
