Tar & Tape drive without media
Hi all,
I would like to know what would happen if the tape (media) is not placed on the drive and a tar command is executed to backup on the tape.
My problem is that tar command hanged for multiple days instead of throwing the error,
Is it valid behaviour?
I was unable to test the scenario as i dont have a tape drive with me.
Regards,
Satheesh

I want to use this command to tar to tape:
tar cf - DIR | compress > `hostname`_`date +%m-%d-%y`.DIR.tar.Z

amverify
AMVERIFY(8) System Manager's Manual AMVERIFY(8)
NAME
amverify - check an Amanda tape for errors
SYNOPSIS
amverify config [ slot [ runtapes ] ]
DESCRIPTION
Amverify reads an Amanda format tape and makes sure each backup image can be processed by amrestore and, if possible, the appropriate
restore program (e.g. tar).
Amverify runs amrestore on each file of the tape and pipes the output to a restore program (if available) with an option to create a cata-
logue of the backup. The catalogue itself is discarded. Only the success or failure of the operation itself is reported.
If the backup image cannot be processed by the restore program, e.g. if it was written on a different operating system, the image is sent
through dd to /dev/null. This still determines if the tape is readable, but does not do any internal consistency check on the image.
If config is set up to use a tape changer, the slot argument may be used to choose the first tape to process. Otherwise, the current slot
is used.
The runtapes configuration parameter determines how many tapes are processed unless it is specified on the command line.
See the amanda(8) man page for more details about Amanda.
