Issue Issue creating backup FTP/Local

[Xelar25]

Server operating system version

Ubuntu 24.04

Plesk version and microupdate number

18.0.67

Hello there!

I'm new to Plesk, it's a new installation, i'm trying to test the backup function via FTP or even local, but no matter what i always get this warning/error.


Warning: Subscription "example.com"
Unable to back up files from /var/www/vhosts/example.com owned by Apache. Error: Failed to create archive: backup_apache-files_2501232245.tgz 0
Repository error: Unable to pack /var/www/vhosts/example.com: tar (child): pigz -3: Cannot exec: Permission denied
tar (child): Error is not recoverable: exiting now
/usr/lib/plesk-9.0/sw-tar: Child returned status 2
/usr/lib/plesk-9.0/sw-tar: Error is not recoverable: exiting now



I've tried checking the two Dumps folder, but the permissions seeems fine. Any tips?

Hi,

What are the actual permissions?

ls -ld /var/www/vhosts
Ls -ld /var/wwwvhosts/example.com

You can run Plesk repair to fix permission and ownership:

plesk repair fs -v

 

[Xelar25]

ls -ld /var/www/vhosts
drwxr-xr-x 9 root root 4096 Jan 22 03:00 /var/www/vhosts

ls -ld /var/www/vhosts/example.com
drwx--x--- 10 example.com_b7qdtl2wu8n psaserv 4096 Jan 22 09:27 /var/www/vhosts/example.com

After running Plesk repair as suggested nothing changed.

plesk repair fs -v

The permissions look ok.

Check if you have files and folders not owned by example.com_b7qdtl2wu8n:

find /var/www/vhosts/example.com ! -user example.com_b7qdtl2wu8n

 

[Xelar25]

find /var/www/vhosts/example.com ! -user example.com_b7qdtl2wu8n

There is a subdomain with osticket installed, i forgot to mention. Everything is working fine in both website.

Those are not a problem.

What did you select in the Backup Manager when the backup was created? Do new backups trigger the same error?

 

[Xelar25]

I tried FTP and Storage, singularly and both together. New backups still throwing error. I tried full backup and incremental, split and non split.

 

[Raul A.]

Can you share a screenshot of the options that are selected?
Do you get anything logged in /var/log/plesk/panel log when the backup fails?

 

[Xelar25]

I solved by reinstalling the system and plesk.

Thanks for the help!
