PROBLEM Backup: connection times out, bad zip file

[Tania]

This is an ancient issue
https://github.com/GetSimpleCMS/GetSimpleCMS/issues/285

No one knows what the problem is, it is very hard to reproduce.

No idea what that mnax is, but when ziparchive is not available on your system we do call some local shell commands like zip via our own ziparchive class, and if that fails we call tar -cvzf

The issue suggests to something perhaps dropping our ajax wait and reloading the page causing several calls, but this makes no sense.

Try a different browser?
Check error logs for php timeouts?

Thanks, Shawn.

I see you guys are working on this, and if you can't figure it out, then I certainly can't, with my limited knowledge.

I'll just suggest to the site owner that he does a backup via his cPanel for now.
