Yes, if you’re seeing a Perl error, there’s a bug, though it may not effect older backups. I’m guessing something changed in the backup and we just don’t know about it. The backup files of the control panels we can import aren’t really documented anywhere, so Jamie just reverse engineers them from actual backups.

I’ll ask @Jamie to have a look. He’ll likely need a copy of the offending backup, or an example backup of a fake domain that exhibits the problem, so the problem can be reproduced.

Yeah, I would need an example of a failing backup to see what is going on here.

Here you go!

Is that link still valid? I tried to download it just now, but the connection to 84.254.0.113 timed out.

Sorry Jamie, line is temporarily down. I have relocated the download, please try:

Thanks, got it! Taking a look now …

Ok, I have created a fix here : Handle case where there are multiple data files · virtualmin/virtualmin-gpl@4bec669 · GitHub
