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

The main point in my post was that the issue may be the tool you’re using to do the uncompress doesn’t work because the uncompressed file exceeds some limit (likely 2 GB). The compress on the other hand worked because the file it created was less than that limit (2 GB). If that is the case you’d have to do what I did OR insure you are using a GNU compiled uncompress utility that doesn’t have the limit (if it exists). For me the tool was gzip and as I noted the Linux version handled the file fine. Likely the version of compress/uncompress you’re using is NOT the GNU version but a proprietary Sun version.

Thanks jeff,

My Netbackup Server is Window 2000 server.

I have taken backup (RMAN files) from Sun server (Solaris 5.9) and restoring this backup on the same server (Sun).

This Sun server is a production server.

We have a testing server of same environment (like production server).

I tried restoring backup (RMAN) of testing server. It works successfully. All files gets uncompressed.

I am worried that my RMAN files are getting corrupted when I am compressing these files and putting it to tape.

Is this holds true ???

What should I do ?

Thanks & Regards,
Vinayak D. Vaijwade

You didn’t say what you used to compress the files or what Operating System you’re using.

I saw an issue recently where one of our DBAs had compressed and sent to tar a file but was later unable to uncompress/untar it.

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.

Hi All,

I am using Veritas Netbackup 6.5 tool. I am facing some problem after the restoration of backup.

I have taken a backup of 'Oracle Archive files' (compressed files) on a SDLT 320 tape (2 months old backup).

Now when I am doing restoration of this backup it happens successfully (Status 0).

But when I am trying to uncompress the files from restoration it gives me the error

"uncompress: file name - corrupt input".

But some of my files gets uncompressed.

I have done restoration from other tape also. It also gives the same error.

Kindly let me know where the problem lies ?

Thanks & Regards,
Vinayak D. Vaijwade
