Hello guys,

Hello,

Could you let us know the contents of the /var/cpanel/backups/config file on this system? Keep in mind that incremental backups make use of hard links, so it might seem like disk space is utilized when it's actually not:

How do the backups work exactly?

Thank you.

Hello,

Can you elaborate on what you are seeing that leads you to believe full backups are generated? Were you able to review the link referenced in my last post regarding hard links?

Thank you.

Whell, i see on the backups on the same account diffrent dates made backup of all the files not the changed only.
Hello,

Can you provide more details about what you see and how you are checking the existence of those files? Please post the output you see in the command line (ensuring to remove any identifying information about the accounts/server).

Thank you.

Hello,

It's likely you are just seeing the hard link to the file. This is explained on the following thread:

How do the backups work exactly?

You'd need to access the server via SSH as root to confirm this by verifying the inode number is the same. EX:

Code:
ls -li /path/to/daily-backup/filename
ls -li /path/to/second-daily-backup/filename
Thank you.
