You'll be able to make an exact copy of the / root system, regardless of what filesystem it uses. Furthermore, you can choose to exclude certain stuff from being copied over to the backup HDD, and all the files will be accesabile like they are on the first HDD. The advantage of this, is that the HDD could be put into another machine, without having to figure out how to restore it. And, you could run a cronob to sync the files every night. -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 -------------- next part -------------- An HTML attachment was scrubbed...
