Verify backup integrity.

Hi,

I'm backing up my file systems using the dump utility and am wondering if there's a way for me to check the integrity of the dump files.

Backing up 3 file systems, 2 of them with the size of around 2gb - 4gb, looked pretty good, no error nor warning. The last one though, which is around 100gb in size(backup and compress), had this came up:

Code: 
swap_pager indefinite wait buffer bufobj

Sorry, didn't manage to capture the whole output. Been reading about it but still am not sure if this is affecting the dump process. Would be nice if I could check if the dump file is good.

Thanks in advance.
 
I guess you could try getting a file listing from it (the -t flag if I'm not mistaken), or restore to /dev/null with some verbose output redirection ...
 
Thanks DD. Thought of the former, yea, -t flag for listing. The latter idea is interesting. I'd try that.
 
I was about to start restoring my dump file to /dev/null when it came to mind.. how do I cd to /dev/null? Lol.

Can shed some light over here on how to restore to /dev/null, if it's possible?

But anyway I ran the bzip2 -tv dumpfile command and the result is ok so I guess it's good.
 
Yeah, I was probably confusing target-like statements in dump and rsync with the lack thereof in restore. I guess the -N flag of restore can also serve as a test bed.
 
Run restore in intractive mode and you use ls command to list files. If there is any error it will tell you on fly.
Code: 
restore -i -f  /nas/usr.dump
OR
Code: 
restore -iN -f  /nas/usr.dump
