CYAN backup does not work with PHP 8

Is it only with PHP 8 or did you try it with 7?

It is only with PHP 8. There is some error report:

Yep, looks like the function has been removed, I’ll take a look and see how hard/easy it is to fix.

I’ve found the issue, can you try the fix by replacing your copy of wp-content/plugins/cyan-backup/cyan-backup.php with this one: https://raw.githubusercontent.com/toolstack/cyan-backup/master/cyan-backup.php

With the provided file, I can now remove old backups. However, the backup still doest not work. It freezes with “Archiving files…” While the .log file ends with

[2022-03-01 08:18:46] Archiving files...

There also plenty of errors in Apache log:

Looks like the zip archive library is broken, I’ll see if I can track down an update.

Ok, I think I’ve solved the issue, can you try version from github?

https://github.com/toolstack/cyan-backup/archive/refs/heads/master.zip

Wow, now it works! It completed with: Backup complete! Thank you!
