B2D Byte Count Differences

Posted on 2007-08-01

We recently started using Backup Exec 10 for SBS B2D for part of our backup procedure.  I'm seeing two issues with this process that I need some clarification on.
First, the byte count in the job monitor is appx 1Gb larger than the byte count on the HD.  Compression is set to hdw if available, otherwise none.  I do not have verification set on the job due to timing, so I'm not sure if this is a good backup or not!
Second, I am moving the file from the HD to an external HD for storage.  I then get a message in the event viewer, "An error occurred while processing a B2D command. Drive: ReadFMTable() CreateFile failed (\\xxx\xxx\DailyBackup\B2D000007.bkf). Error=2 For more information, click the following link: http://eventlookup.veritas.com/eventlookup/EventLookup.jhtml"  This message is actually referring to the backup I moved, not the "new" one.
We would actually like to write that backup to tape, however, I am concerned about the validity of "backing up" a backup.  Some instruction on whether this is feasible or not would be appreciated.
Thank you.

If the backup job does not show any errors, and it says it completes succesfully then you don't need to worry - you will have all your data. I assume the difference could be down to Exchange Single Instance Store backup, or SQL not backing up empty pages for example.

 Error 2 in the other problem means "The system cannot find the file specified.". That's normal, because you moved it. You should copy the file instead of moving it. You could then reuse the existing B2D file for the next backup by setting correct overwrite protection value.

But you're also correct that tape may be a more valuable option. The best way to write the B2D files to tape is to run a duplication job.  This does not just back up the bkf files associated with the B2D, but rather unpacks them and writes the individual files inside the backup to tape. You can set up a duplication job to happens immediately after the B2D backup finishes or you can schedule it for a certain time of day.
