error 213

It might be attached to a transaction that's damaged or corrupted, Annette.

You will need to delete it since the rebuild didn't resolve the error. 

Once deleted, rebuild your file once again before recreating the transaction. If you're still getting the error, please contact our Technical Support Team. They will help you read and review the log files, as well as making sure that you can create a back up. Here's how:

I am getting error 213. Also why always rebuilding?

If it is always prompted to rebuild your file every time you run a backup process, the rebuild process was not enough to repair your file. Don't wait until too late.You should chat Support and ask them to fix it immediately. Otherwise, you can ask a third party service provider for a second opinion.
