Recovery using ftio

Hi,
Anybody used ftio (faster tape I/O). I have a tape that was backed up with ftio. I have to restore it now. This was done on DLT tape drive set with 20 GB, compress and density override mode. And also the tape was made with the block size of 32k.
I have tried different options like "ftio -icdmv and -Icdmuv" with no luck.

Any ideas.

Thanks.

To extract let's say you have tape drive /dev/rmt/0m:

# ftio -idxE /dev/rmt/0m

Re: Recovery using ftio

We pipe a relative find into the following ftio command:-
ftio -ocxv -B 32k /dev/rmt/0m to backup.
In order recover we use the followng ftio command after cd'ing to /
ftio -icvdum -B 32k /dev/rmt/0m (back to the same machine).

'ftio -icvx' is what sticks in my head. 'ftio -icvt' is like a 'tar tv'--gives you a listing of what's in the archive. Probably you should try '-icvt' first to be sure of what's actually in the archive.

You might try NOT using the '-c' option if you're still having troubles. If you're certain the backup was created with a 32K block size, you'll probably need to also specify '-B 32k' like Darren said, since 16K appears to be the default.
