Clone a 300Gb disk on a periodical base on Linux(Fedora5)??

Good day! I have a linux server with 2 disks (300Gb).At first i wanted to do soft raid-1 mirroring, in case one of them fails. Soft raid-1 have disadvantage that it have to write data 2 times and i lose in performance. I want nightly to clone entire drive , so even if a hard fails i loose at least no more than 12 hours changes of my data. Yesterday i used /bin/dd in a ctontab, to clone my drive. In the morning it was still running,and i had to kill it. It run for almost 5 hours !!! I guess i have to use some other tools, more quicker, what do you recommend????

Thanks for your time!

Hi bytelock,

Don't try to mirror your disks using any tools as your disks are very large in memory.
You should go for some backup utility or may be scripts so that you don't repeat unchanged data backup.

Try using some backup utilities like BackupPC I don't remember other names but u may find on gooooooogle.
