Failed while executing "Backup" System.Xml.XmlException: '0' is an unexpected token

------ Resolved ------

Hey,

We’re having an awful time getting 700GB backed up on a Windows 7 32bit machine running Duplicati Beta as a service (Canary didn’t help). It is backing up a Windows Server 2003 machine over a SMB mounted drive

It gets through a sizable portion of the backup, then throws this error:

Another error it throws is this:

System.AggregateException: One or more errors occurred. ---> System.AggregateException: '0' is an unexpected token. The expected token is '"' or '''. Line 2, position 33. ---> System.Xml.XmlException: '0' is an unexpected token. The expected token is '"' or '''. Line 2, position 33.

Couldn’t find anything online regarding this, any ideas where the issue might be?

Thanks!

Edit: Looks like the seafile storage I was backing up to was corrupt, an FSK fixed it. Seemed to happen a lot, very large duplicati backups can be hard to finish
