The biggest problem with something like dd is that the disk you put the file back onto needs to be the same type of disk. Pretty much exactly alike. Size will matter. So will other little things. Best to find a different solution. I believe there is a Ghost for Linux. There are other applications, but I don't have any of them. I thought I would write and clarify that not to leave you thinking your were going to be able to get any disk later on.

Why not dd and pipe through gzip back out to a file? This will take care of anything that can be compressed. Empty space won't be as big of an issue. It should pack pretty nice.

Hi, What is the best way to backup a whole disk? (Like ghost under DOS/Windows?) Can I simply dd -if /dev/hde -of /home/backup/backip.img and dd it back when necessary? This, if feasible, is not at all efficient since empty spaces are also copied. Is there any better way? I can not use tar/cp -r since I would like to keep partition information as well. The whole story is that I need to backup a disk before I resize an ext3 partition on it. I hope parted will do the job well. Any success story? Many thanks in advance. -- Bo Peng -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
