I've just installed an Sony SDT9000 Tape drive (DDS3 DAT) I'm having a heck of a time figuring out a bunch of things. 1) how do i figure out how much room is left on a given tape? 2) how do dump to the end of a tape (i.e. after the last dump rather than at the start) after it's been rewound? 3) how do I restore incremental backups after the first? restore -t doesn't show anything but the first. 4) what do i do about compression? It's a 12/24 GB tape, so I'm thinking I put "dump -0u -B 12582912 -b 64 /dev/nrsa0 /" but that won't write to 24 GB which the tape drive is capable of with compression. Is there any way to enable that? 5) Finally, last night i was trying out flexbackup (the perl front end for dump/cpio/etc) and the tape drive froze (something about "This tape doesn't have an index at /usr/bin/flexbackup line 2385".) and sat there for over an hour not doing anything. So I killed the process and tried to kill the "mt -f /dev/nrsa0 erase" but it wouldn't, and any attempts to read/write/mount etc came back with a device busy. I eventually just restarted the box, but is there any way to stop this? Thanks for all your help.
