tar exit status

I am using tar to backup files to tape.

When the tape is full, I'm prompted for a second tape and told to press enter when ready. When I press enter, tar stops and gives an exit status of 5. Does anyone know what this indicates?

Also, if everything fits on one tape and the backup completes, I am getting an exit status of 1 (should be 0 if completed sucessfully). Any idea why?

This is the command I use (executed from a unix script) :

tar cvf /dev/rmt/1m `cat filelist`

(the filelist just contains \ so that everying from root down is backed up).

If you are using SUN OS then you can try using ufsdump instead of tar for multi volume backups.

You can create multivolume backups with tar. From the man page:


-M, --multi-volume
create/list/extract multi-volume archive
TAR is quite powerful...... here is an example of the range of options from the man page:


tar - The GNU version of the tar archiving utility

--diff --compare | r --append | t --list | u --update | x

filename1 [ filename2, ... filenameN ]

directory1 [ directory2, ...directoryN ]
Tons of options !!!!

MultiVolume backups can be done with tar but ufsdump can be thought of as an another option.
