Some email missing after restoring from backup

Hi,

I accidentally deleted all the emails from an account. My host sent me a full backup that I extracted on my computer. I transferred by FTP the account folder which is under homedir/mail / domain.tld /
When I went to check in the webmail, I found the emails sent but none of the emails received.

Was the backup I received incomplete or i didn't rasturation properly?

Thank you
