How does everyone feel about using Quantum LTO 3 and 4 tapes with Bacula for backing up both the VM's, Host, as well as from within the VM's.
What are know good backup solutions? Can anyone name specific tape drives / software that is working.

We used bacula to hotswap SATA disks. It worked great.

There is little argument for tapes at all in modern backup systems unless you need archival storage and you have money to burn on media, time (backup/restore time as well as time lost during restore on the requesting side), staff, etc. You are better off and you will get more business value from one or more DR sites, replication, and NLS for backups in one or more locations. You will probably end up spending less overall if you just use the aforementioned hot swap SATA disks instead of tapes.

We think of our 320G Quantum Sata DLT-4 tape drive as 'hot-swappable'. The tape is easily replaceable, without having to worry about bad connectors that can plague hot swap drive bay equipment.
At $45 per tape for 320G of storage, it competes with hard drives. In case of tape drive failure, the tapes still work with the new drive. And with scsi or sata based tape drives, speed is not a problem.
Combined with disk based network storage, tapes have a place in IT.

...or, with 750GB drives today, you could more than double that storage for 25% more per unit. Tapes are more durable than hard drives, but they're hardly impervious, and they certainly aren't higher density when you start backing up many TB.
