moving/cloning != backup
right. The use case I meant was more like a poor man's snapshot of a physical machine: copying everything 1:1, trying something completely weird, and then restore the snapshot if necessary. ;-)
I thing that comes under the "there's more than one way to do it" column, since there are specific tools for snapshotting, especially with very modern FS. Many implement a disk-to-disk-to{tape,optical...} strategy and retain that second disk for a short while as a snapshot or might have a rotating set of backup disks. I've seem a lot of variations on all this and more often that not I've found that people who do full image backup ("because its simpler") get themselves in a mess whe they use that for selective restore. The OP wanted a full image but if he was junking the old drive and installing new and then install a new OS then he would not want a full copy of the old. Clearly identifying what has to be preserved is the important thing her. Obviously /home, obviously spooled email, obviously account information from /etc, but anything more if IF..IF..IF Either way a file based snapshot is required. On the other hand, if, a in other parts of the thread, it was a dd of the raw device and a dd back to a similar replacement device, then upgrade in place ... -- The eye sees only what the mind is prepared to comprehend. -- Henry Bergson, French Philosopher (1859-1941). -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
