well /dev/rmt/om is not a normal device to use, it should be /dev/rmt/0m (note the numeric zero and not the alpha o)

Hi soobe,
You are not using exact syntax.

tar --> achives the tape file.Commonly we used tar command for backup.we can also use fbackup.

tar -cvf /dev/rmt/0m /backup

c --> create
v --> echoes filenames to screen
f --> designates file where achive will be written

/dev/rmt/0m --> Backup media [Tape here]
/backup --> Target whose backup is required.

Hi,
as melvyn states: /dev/rmt/0m

You should also specify what you want backing up.

You can check your tape device files with:
ioscan -fnC tape
