[Borgbackup] FileExistsError re nonce.tmp / nonce

[Matthias Böttcher]

Hello Michael,

I guess you have mounted /mnt/synology/ as cifs on a Synology NAS.
Please check the SMB-Settings on the NAS, especially the version
settings of the protocol. I can't give you detailed information,
because I'm not using a Synology NAS.
