Re: [Veritas-bu] "Successful" NDMP Backups Missing Data

You might want to verify your policy “selections” included everything and also that you don’t have an exclude list specification on the client that would have made it skip certain things.

It would be very bad indeed if NBU gave a status 0 for backups that didn’t backup exactly what they were told to backup. My first suspicion would be that this didn’t occur – that either its not in the selections for the policy or it was excluded due an exclude list.

Of course there are other things that could cause this – e.g. do not cross mount points, don’t backup NFS etc… that might have been set on the policy by default.

Subject: [Veritas-bu] "Successful" NDMP Backups Missing Data

I'm looking at an Full NDMP backup from this past weekend. According to the activity monitor it was Status - 0 Successful. However, when drilling down into the data via Backup and Recover I notice that certain key folders are missing. Upon further inspection, I notice the past 4 weeks backups look something like this - 833GB, 833.2GB, 833.7GB, 780GB. Although Netbackup gives me the "0" I'm obviously missing data. I just opened a case with Symantec (they will call me tomorrow), and I'm pretty sure the data is gone but can anyone give me any hints on where to start troubleshooting this? The good news is that it looks like MOST of the data made it to tape. The VERY BAD news is that 100% of the data was not written to tape and that Netbackup did not give me an error.
