Re: [Veritas-bu] Netbackup Post Restorastion issue.

The issue described by OP wasn’t
that files were missing but rather that they couldn’t be uncompressed after
restore. My read of what you wrote is that the files would be missing because
NBU didn’t know to back them up.

Netbackup Post Restorastion issue.

This was because the tar and gzip/gunzip
commands on HP-UX 11.11 are not the same as the ones the average Linux distro
would have. Essentially the HP-UX versions couldn't handle files
larger than 2 GB (despite the fact the filesystem itself could). I
was able to solve the problem by moving the bundled file off to a Linux server
and doing the tar extraction and gunzip there then moving the uncompressed file
back to HP-UX. Note that before doing that I did try using the tar
that comes with NetBackup since it is a modified GNU tar but that didn't help.
We've also seen some fun issues with compress utilities on Solaris (and
possibly HP-UX - I can' remember). The compress would set the creation
date of the compressed file to the creation date of the archive log. This
caught us early on when the compressed file appeared to have been created
*before* the last backup so the next backup would skip it. A simple
"touch" on the compressed file solved that problem.
As always, test your backups. At a minimum, do a regular bplist to make
sure you're backing up what you're supposed to be backing up.
