You can use Regex to exclude temporary Office files:

> [@Excluding MS Office temporary files?](https://forum.duplicati.com/t/excluding-ms-office-temporary-files/242/2):
>
> Try using this regular expression: -[.\*\\\~$[^\\]\*]

Or run Duplicati with administrative privileges and use option [–snapshot-policy=required](https://duplicati.readthedocs.io/en/latest/06-advanced-options/#snapshot-policy) to create a snapshot before the backuperation is started.
