Backup Sets for Long Term Storage

[Haskins, Mike]

Our TSM server has a 3494 library with 3590 tape drives.  Now faced with
meeting long term storage requirements (7+ years), I am looking at
generating backup sets to accomplish this.  Since backup sets can be
used for stand-alone restores from a backup-archive client, I am
thinking that a different media type would be better than 3590.  There's
not much chance that many of my nodes could have access to a 3590 drive.
DLT or 8mm seem more appropriate.  Any experiences or opinions would be
appreciated.
