OK. That makes a good deal of sense. I have to assume then that the backup program doesn't actually store the attributes with the file, but in a separate store of some kind. Especially in the case of a raw dump type utility. This would explain why, when my restore completed, I am prompted with a question asking if I want to restore owner:group attributes. So, my files are probably written from the tape to the drive with the owner:group set to the user who is running the restore (in my case 'root'). Afterwards, the final process runs through the restored files and then does a chown on each of them. Hehehe... I think there is also the distinct possibility that the tape drive I'm dealing with just has crappy performance in Solaris too.

I backed up a unix database using
"tar -cvf /dev/rmt1 -N 800 /*"
Normally I would restore this using
"tar -xvf /dev/rmt1 -N 800"
This is reporting an error about
"not enough memory"
I have done a new test backup and restore using the same commands and they work.
ANY IDEAS ? (2 Replies)

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.
