I am trying to take full farm backup using PowerShell and from CA in 2019 SharePoint. but I am getting error
Object WSS_Content failed in event OnBackup. For more information, see
the spbackup.log or sprestore.log file located in the backup directory.
SqlException: Cannot open backup device '\\servername\spbackup\spbr0000\00000089.bak'.
Operating system error 3 (The system cannot find the path specified.).
BACKUP DATABASE is terminating abnormally.
The permission has been given to SQL server account and also to the farm account and also shared the folder to SQL server account and farm account it creates other .bak but fails only some of the .bak files.
What is the solution for this error?
