Failed Backup to NAS over SMB

Support
#1

I configured the backup job which ran about 4 times with no issues. Now each day there is an error in the output when the job is done Failed Backup.

Here are the last few lines from the failed output:

Could be a permission issue? What type of storage backend?

Hi thanks for the reply. It’s a Samba server.

I’m quite sure the login creds are the same
