Backuping and Restoring LOGS

Hi:

I'm trying to setup a new clean Astaro installation. I have a Astaro server where I took over SSH with WinSCP all the logs files (\var\logs) to my hard disk, after I copied all those logs to my New clean installation ASTARO. I restored the new installation with the backup of the old astaro

In the new installation I found all those logs but in the Web Usage Report I don't have any report

Somebody can't help about it

Regards
