Automated System Recovery question

Hello everyone,

I create an ASR(automated System Recovery) set for our 2003 server. I started the ASR wizard and I pointed the backup to a location other than the system partition.

Everything went fine, except the size of the “backup.bkf” was 47 GB. !! I thought ASR only backs up the system files. The Servers’s hard disk is 80 GB(67 used)..
Am I missing something ???

I would appreciate any help!!!
Regards,
