for the last 2 weeks I receive the following error after backup completes.
It looks like the backup was successful. but we still get the error.

• An error occurred (code: 1003)
Incorrect function. Position 1358513664 count : 512 . ErrorCode:1 HR:80070001
Please contact support

any idea what this means or how to resolve it?

When we first got the error we were running version 7.8.7.59 . But it still occurs after updating to the latest build.
