@DavidHertzberg Great! Where is my participation trophy?!?
I wouldn't think it could matter. I've been using Retrospect since v4. I'm on a Win10x64 machine running 16.6. Remote NAS is a Mac with SMB share.
I watched the video and had performed those steps without issue. I checked the last step again to set automatic login. When attempting an execution of the backup script it still asks me to add a disk to add as storage. The only difference is the catalog file is stored on a local NAS vs DAS. Automatic login is/was set for the local NAS.
I then recreated the backup set with the catalog file DAS and the disk backup set via the site to site VPN on the remote NAS. This works fine, and it tells me there is a bug in Retrospect that needs to be addressed. Why would I not be allowed to have a catalog file on a NAS? The GUI allows me to set it wherever I want, yet the backup fails consistently.
