backup on solaris 5.4

Hy everybody,

I would like to know how i can do a backup or an equivalent of a ghost image like on Windows but for Solaris 5,4. I know there is the command flar or flarcreate but it doesn't work on Solaris 5,4. If someone have a idea to help me please.
Thanks a lot.

how about "ufsdump" and "ufsrestore"?
