if you can afford it, i'd make a periodic copy of the dump device to another disk in the same machine. i might even consider just copying the whole disk. since cwfs (and venti) have a worm structure, you can also (or additionally) back up incrementally to optical media. backup(8) has some details on some excellent work geoff did, but it might be a tad venti-specific. since i am used to having rather large worms, and i don't have a blu-ray, i usually use vblade(8), or a hardware aoe target to present a disk, partition, or file as a target for backup images. - erik
