We have a NAS, there are files on it, only through the network.
How can I make a backup from a network drive? If I connect a network drive, it does not see it. Right too. Can I somehow use a network drive as a source?
ver. Duplicati - 188.8.131.52_canary_2019-09-05
error: Unauthorized to access source folder \10.50.8.152\Accounting, aborting backup
Are you running Duplicati as a Windows service? That doesn’t see the drives the users do, and fixing that is problematic according to Microsoft. UNC source with credentials? suggest Active Directory can help, but do you have it available, or are you just having people type in credentials, maybe with Credential Manager help?
I’m not sure what other steps are needed. It might need some help, but at least it could access the share.
Service install - Backup to a network share (ie. FreeNAS) may also be of interest, and explains how using ordinary user account for the service can get into a password change issue for the service if the user ever changes passwords. If this is a problem for you, information is available on the Internet on how to handle it.
