Brand new HP MSL-2024 LTO-4 cassette tape system, holds 24 LTO-4 tapes capable of holding 1.6TB each (compressed). Backs up ~860 GB/hr. <http://tinyurl.com/24vjxsw> Tape still rules for backups; when I mentioned Disk-Disk I'm referring to our preferred systemof having another large SAN, backup the production volumes to the backup SAN, and then run the tape backups off of that. Much faster primary backups, sort of like a giant CCC backup, which makes for very fast restores, and keeps the production volumes at maximum availability longer.
