Re: Tape/DVD Backup Suggestions?

I used Exabyte tapes for severeal years, very reliable. Sometimes there were
problems with media from different vendors. I usually used 2 tapes for parallel
backup/recover sessions and for fault tolerance. I would backup to harddisks only
in rare cases and I don't user CDs etc. for backups.
