I've done mutual mirroring like that with rsync on nix boxes before. It worked well. I expect you could do the same on doze with rsync, Unison, or DFS-R. > ... its reliance on hard links means it's not feasible to use rsync to > mirror it to an offsite location. rsync handles hard links fine on nix. I've never tried that combination with doze, though -- I take it there's a problem there? (As an aside: If you have nix systems, and want rsync for backups, check out rsnapshot. It lets you keep what appear to be multiple complete copies of a nix filesystem on a disk, but uses hard links to de-duplicate files, implementing copy-on-write semantics on a per-file basis as needed. The best part is that the backups are just a standard Unix filesystem, so there's no special restore tools needed. You just read the files like you normally would. Kind of like VSS, except it doesn't randomly discard snapshots when subject to heavy I/O.) -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
