I have set up a backup to Amazon S3 and it seems to be working. However, when I do a restore to test the backup, I get no errors but 1 warning:
“2026-02-20 15:00:06 +00 - [Warning-Duplicati.Library.Main.Operation.RestoreHandler-NoFilesRestored]: Restore completed without errors but no files were restored”
In order to do the test I moved one of the directories that I am backing up to another drive and then tried to restore the directory from S3 to its original location. The restore quickly completes, which is surprising as the directory that I am trying to restore is 13GB and I get the above warning.
