V-79-57344-759 error for ms exchange 2010
I have an issue to backup our ms exchange 2010 database. It always happen on last day(Friday) for my differential backup and full backup on Saturday. The error message always the same which is "V-79-57344-759 - Unable to complete the operation for the following reason: VFF Open Failure. This can be caused by low memory or disk resources. ". I already do below solution to counter this issue but it always fail to backup now. I did try to manually trigger full weekly backup but it still fail and receive same error message.
For additional info, it always give different database error each time backup fail. Below is the server spec:
- Intel Xeon 2.5, 16GB RAM, Window 2008 R2 Standard.
Can anyone help me regarding this issue.
Thank you in advance.
