"Mirroring" (in the sense of making a duplicate, not in the RAID sense) should be a trivial operation. I, too, use a plug-in drive drawer which contains a disk that matches the internal system disk. I duplicated the system disk to the removable disk using dd on a quiescent system: dd if=/dev/rad0 of=/dev/rad4 This copied _everything_ - boot block, disk label, filesystem info, user files - in one go (i.e. a byte-for-byte duplicate of the entire contents of the device). It did take awhile (30GB ATA 7200 RPM), and requires that the disks be physically alike, but it's the simplest way I can imagine to make a truly duplicate a disk. After the dd I can mount each partition independently (e.g. to /mnt) and find everything exactly as it appears from the original. The duplicate disk is a convenient backup, easily ports to other systems in its plugable drawer, can substitute for the system disk after a disaster, and is suitable as the system disk in a clone system. This is not a substitute for a well managed backup plan. But with disks being inexpensive commodity parts, it was an easy way to duplicate my system disk after I confirmed that I had a good fresh installation and get the peace of mind that my foundation is secure. -- Bradford Castalia Castalia@azstarnet.com Systems Analyst http://azstarnet.com/~castalia idaeim 520-624-6629 "Build an image in your mind, fit yourself into it."
