Question What is the use of /home/system folder (clone?)

[destan40]

The domain user data are stored at /home/domain.com
now i see the exactly same data are stored in /home/system/domain.com

I can not see a symlink?, so i also tried to delete /home/domain.com/logs/error_log
but then in system folder the file its not deleted,
and only delete from /home/system/domain.com free up storage.

How it works, what is the use?

These files are hardlinked... Both file names point to the same inode, so deleting just the one file name won't remove the content and free the disk space.

For the answer to your question, refer to the following Plesk support article: Why there are two locations for domain log files in Plesk?

To recreate the files, either refer to the How to recreate log files hardlink structure for all vhosts? support article or, for a single domain, use:

plesk sbin relink-vhost-logs --domain-name example.com --sys-user-login <user_name> --create

Also... generally speaking, when in doubt, research first, delete later...
