Issue Backup Manager is not working

[max2334]

Server operating system version

Ubuntu 20.04

Plesk version and microupdate number

18.0.73

Hi everyone,


since recently my Plesk Backup Manager stopped working.
When I click on the Backup Up button I get redirected to

https://vserver.de:8443/cp/home

and the following error appears:



Error:

Unable to create the remote backup: Curl error: Unable to resume an interrupted upload: (55) Failed sending data to the peer:
The last FTP request: APPE backup_2510010351.tar1
The last FTP response: 150 Using transfer connection: Connection to the FTP server has lost..


Even though I removed the FTP server settings for testing and tried to create a local backup on the server, the same error occurs.


Environment:

• Plesk Obsidian (version: [insert your exact version, e.g. 18.0.72])
• OS: Ubuntu 20.04 (planning to upgrade to 22.04 soon)
• Backup Manager previously worked without issues

What I tried:

• Removed remote FTP storage settings
• Attempted local backup only → same error
• Restarted Plesk services and server

Does anyone know how to fix this error or what might cause Backup Manager to fail like this?


Thanks in advance!

Hello, @max2334 . Could you please check for potential stuck backup tasks:

ps auxfw | grep backupmng | grep -v grep
ps auxfw | grep pmm | grep -v grep

there is not tasks running..

Thank you for the update, @max2334 . My other guess is that the FTP settings are not properly removed from the Plesk database. Could you please try the following:

1. Create a backup of the Plesk database just in case:
   

   plesk db dump psa > psa_backup.sql

2. Execute the following command, which should remove the entries of the FTP details:
   

   plesk db "delete from BackupsSettings where type='server' and param like \"backup_ftp_%\""

I hope that helps.

Thank you for the update, @max2334 . Unfortunately, I am out of suggestions on what else might be causing the issue. I would suggest opening a ticket with Plesk support for further investigation on your server. To sign-in and open a ticket please go to:

• https://support.plesk.com

If you got your license from a reseller, your reseller is in charge of providing you with support. You can raise the inquiry with them and they can forward it to our team for further processing.If the reseller does not provide support, here is an alternative to get support directly from Plesk:

I purchased my key via Hetzner, if I enter my key, I can not see the create support ticket button? But my provider told me, I need to create a support ticket directly in plesk?

As @Sebahat.hadzhi said, if your license is through a reseller then your reseller is your support. If they are not able to provide you support you can refer to the second link that shows you how to purchase support to get support directly from Plesk.

I'm investigating an issue on my Plesk that I noticed today. I don't know how long it has been there.
I have plenty of updated backups [1], but the backup interface says I have none.
