How does the cost compare to just > buying an external USB hard drive? ---- tape has 2 advantages... 1 - portability 2 - multi-state Multi-state means you can have multiple copies, archive versions, various copies over time. That doesn't mean you can't do the same with external hard drives, but external hard drives require a bit more planning and probably more cost. I like to have several layers of backup. RAID - initial redundancy...keeps you up and running Tape or hard drive - rotational redundancy, several weeks of rotation which gives me several copies of the same files Tape or hard drive - archive redundancy, snapshots retained at various time increments Craig -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
