Had a quick search around but didn't really find anything that fits my question.
I have a backup script here that's been in use long before I worked here. The main part of it is:
Inside tar_exclude there is -
The script backs up dir1, dir2, dir3, dir4, dir5, dir6, dir7, dir8 and dir9. Yet these are listed in the exclude file? As is /tmp, which is not listed initially. I don't really understand what it is doing.
I guess it has something to do with the "." in red? And it is to rmt0 and not rmt0.1?
Thanks in advance,
Rab

I think I may have worked it out:
tar cvfX/dev/rmt0/scripts/tar_exclude. 2>&1
Does this mean...
Backup to rmt0 but rewind the tapeeverything in the current directoryexcept tmp, dir1, dir2, dir3, dir4, dir5, dir6, dir7, dir8 and dir9

Reason: Updated title
Once upon a time, tar supported the notion of "options" followed by parameter tokens that were to be supplied in the same order as the options. In your case '/dev/rmt0' would match the f option and ./scripts/tar_exclude' would match the X option.
With GNU tar (most common these days), the command line flags are consitant with other commands and thus the -f option takes the absolutely next string and uses that as the output file, so -cvfX creates the tar archive into X and does not see the X as an option but as a file to include in the archive. Try this syntax:

Didn't see your last bit before I posted my response. It's been a long time since I've played with real tapes, rmt0.1 probably is the device that does not do a rewaind operation after the device is closed. This keeps the tape positioned to the spot just following the previous output -- ready for the next archive file. Writing to rmt0 will rewind the tape on device close and so the tape is nicely rewound after the script is done -- and thus the last output should be /dev/rmt0 as is in your script.

Coming from this thread, just wondering if there is an option to check if the Tar of the files/directory will be without any file-errors without actually making the tar.
Scenario:
Let's say you have a directory of 20GB, but you don't have the space to make Tar file at the moment, and you want... (14 Replies)
Quick question,
is it possible to make a Tar of completely directory and placing the tar file in it (will this cause even the tar file to tarred ?)
sample:
/opt/freeware/bin/tar -cvf - /oracle | gzip > /oracle/backup.tgz
will the tar file backup.tgz also include backup.tgz ?

I would like to confirm my file.tar is been tar-ed correctly before I remove them. But I have very limited disc space to untar it.
Can I just do the listing instead of actual extract it? Can I say confirm folder integrity if the listing is sucessful without problem?
