Error:

Backup source “\\Server\Share ” does not exist!

Cause:

The source location cannot be accessed. This is due to:

1. The location simply not existing, OR
2. The network location requires authentication (perhaps it’s joined to a windows domain) and since the backup process is running under the “Local system” account, the backup process does not have permission to access the network resource.

Resolution:

1. Enter a valid network users account details into the “Windows Resource Authentication for Windows” settings within the backup software.
2. Failing the above option, the “Online Backup Scheduler” system service may need to be run as a domain user with appropriate network rights.
