11.5.30 Update #21 subscription backup failure: Unable to find Backup dump object

[burnley]

Apparently (I'm not at all sure), after updating 10.4.4 -> 11.5.30 the subscription backups fail with "Unable to find Backup dump object" error. I've seen this error reported by other users in the past, for both Windows and Linux, but couldn't find any clear resoultion yet.
In php_error.log I see:

It seems that the issue is with ftp connection. So please make sure the following:

1. Login to ftp server(using the credentials mentioned in Plesk server) is working from the Plesk server.
2. Able to upload the file with same size to the ftp server from Plesk server

However you can try the below solution:

If this is the case try the following solution:

1. Start Registry Editor (Regedt32.exe)
2. Navigate to the following key in the registry HKLM\SOFTWARE\PLESK\PSAConfig\Config.
3. Set 18000 in FtpRequestTimeOut
4. Quit Registry Editor.

Igor, the backup is done locally, I don't think there's any ftp involved. In fact, I've tested the backup job on 3 different subscriptions, including a test one created for the purpose of testing the backup and they all failed in the very same way.
L.E. Just checked the Windows 2008 R2 server running this Plesk instance and there's no such path in the registry, tried both regedt32.exe and regedit.exe
