Copy error to Backblaze

Using Duplicacy to copy my local Vertical backups to Backblaze.

I’ve got 3 virtual machines all backing up fine by Vertical Backup via NFS storage but one of them always refuses to copy to my Backblaze bucket.

Failed to upload the file snapshots/OpenVPN Access Server 2.0.12@BoxroomESXi01/1: Maximum backoff reached

The virtual machine is a virtual appliance. Something to do with the VM machine name perhaps?

This is likely caused by the spaces in the virtual machine name. Which version of Duplicacy are you running? The latest version 1.2.1 should have this issue fixed by https://github.com/gilbertchen/duplicacy/commit/ffe04d691bb866795bfe69e8d20f48c51e3bfaaa.

Currently on 2.0.10.

Will try the updated version. Thanks.

Sorry, the latest version of Duplicacy is 2.1.1 (I got confused with the latest version of Vertical Backup which is 1.2.1).
