Database Full/ Operating System Error 5

Good day to whom this may find.

Im currently trying to set up an sql back up job through SqlBackup 11.5.2 and when i try to choose the file destination (no matter whether its locally or over the network i get the Operating system error 5. I have already tried following the steps provided by:, yet it still wont let me back up to my NAS. All credentials are correct and permissions is set for me to do everything but i still cant back up, and it will shoot me with “database full” even if it isnt.


Thank you for the details. Could you please tell us, are you able to perform a backup of that database to the selected folder via SQL Server Management Studio?
