[Discuss] raid issues

[jack at coats.org (Jack Coats)]

Tapes are acane, but they still work.  When I did backups for a living, I
liked IBMs TSM.  We kept one copy on local backup disk, one copy or two on
tape onsite, and one or two on offsite backups.

Some folks I worked with did backups for a nuke power plant.  They had one
offsite backup on optical disk, two onsite on optical disk, plus tapes and
regular disks available for fast access.  What you do just depends on your
needs and budget.

The last major company I worked for a few years ago used TSM.  They backed
up locally and did a backup to a remote data center, in addition to sending
tapes 'offsite' regularly.
