* and dump | restore to it. Can anyone think of a way I could maintain an * entire mirrored system without ccd, perhaps some software that nightly * looks at the changes on one drive and puts them over to the second without * basically rewriting the whole thing. Partition the drives as root / the rest, ccd the two "rest" partitions and partition them as you wish (/var, /usr, /usr/local, etc.). Write a script that does the following every night: newfs /dev/rsd1a mount -o async /dev/sd1a /mnt cd / find -dx . | cpio -dump /mnt umount /mnt Granted, this will leave a small window of vulnerability during the script is running, but if the root partition is small enough, it should be real quick.
