Re: How to copy data from DDS tape to UNIX station
if the format of the data on the tape is unknown, try to extract some data and analyze this header:
dd if=/dev/tape of=contenttest bs=5k count=1
file contenttest
The output of the file command will lead to the writing program, if it is a 'usual' candidate.
Read the man page of this program to get options for reading data it created.

Re: How to copy data from DDS tape to UNIX station
The opposite of tar is pax or tar:
tar -xf /dev/tape-device
pax -r -f dev/tape-device
>there that is FSBACKUP.
fsbackup or fbackup(1m)? Use frecover(1M).

Re: How to copy data from DDS tape to UNIX station
This will list every file on the tape without actually restoring.
/usr/sbin/frecover -I /tmp/index -vy -f /dev/rmt/0mn
Here the frecover index writes to the file /tmp/index.
tar -tvf /dev/rmt/0m (0m = yes rewind / 0mn = no rewind *)
Here the tar TOC writes to STDOUT
These are previews of the operation.
When ready
tar -xvf /dev/rmt/0m (* for absolute restore *)
frecover -xvf /dev/rmt/0m (* absolute restore *)
Note: Make sure you know if its a relative or absolute resotre. As you'll overwrite anything in an absolute.

Re: How to copy data from DDS tape to UNIX station
pax(1) and gnu tar have options to change the paths.
