Hello, this is the problem [image]

My guess is a corrupted backup file.

Seems likely. But just possibly the problem is that the backup file has already been uncompressed - perhaps uncompressed when downloaded - and so is not in good shape for the restore. Check the backup file with ls -l filename file filename gunzip -tv filename tar tfz filename

[image] Ed S: But just possibly the problem is that the backup file has already been uncompressed - perhaps uncompressed when downloaded That seems like the most likey lway that the backup could have been corrupted (given that it was uploaded and not in the same place where it was created). It seems that some browsers and/or OSes “helpfully” uncompress things immediately on download, or otherwise make it hard to tell that it’s been changed. I think Windows makes it exceptionally hard to tell if that has happened, as it explicitly hides extensions by default. [image] Ed S: ls -l filename If you’re using an OS where someone is likely to use those commands, it’s probably unlikely that it’s caused the problem. :wink:

Yes, I was supposing a person was logged into their Discourse instance. If we offer a GUI method to recover a backup, for people unfamiliar with the command line, perhaps that code can include some check on the backup file and at least report the size and type if the uncompression library throws an error.
