I have installed this new beta in a couple of locations. So far, most things appear to be working as expected.
I still have the problems I have mentioned in this post for the release of 2.3.0.4 stable.
Also, when using multiple destinations I noticed another strange issue. Prior to Duplicati including multi-destination backups I had several endpoints where I had implemented them manually via rclone to copy the backup files to an alternate site.
I tried to shift this functionality into Duplicati by adding the second destination to the backup job in Duplicati. It “worked” but it deleted everything in the second destination and then re-uploaded it all, despite the fact that it was 99% the same files.
