I use fssnap and ufsdump for regular backups by way of Amanda. I have run trials of recovering a system from ufsdumps. Boot off CDROM, plumb network interface, temporarily open up rsh between the two machines on our local private network, and do a ufsrestore from a remote tape drive. Instructions for all of that are in the Systems Administration documentation collection for Solaris on docs.sun.com. If you have a local tape drive, of course, it is slightly easier. I actually had to do the disaster recovery for an E450 running Solaris 8 using a remote tape drive a few years ago. It worked.
For an additional option, I'm in the process of setting up a custom boot CD that contains the Amanda client for a special recovery identity (so it is already set up on our DNS with an IP and doesn't conflict with any machine already on the net), that will allow me to boot off CDROM and then do an amrecover, accessing the Amanda server and tape drive to recover from.

amtape
AMTAPE(8) System Administration Commands AMTAPE(8)
NAME
amtape - Control Amanda changers
SYNOPSIS
amtape [-o configoption...] config subcommand [subcommand_options...]
DESCRIPTION
Amtape is the command-line interface to Amanda's tape changers (amanda-changers(7)) and to the taperscan algorithm (amanda-taperscan(7)).
Tape changers maintain a notion of the current slot for each configuration. This may or may not correspond to an actual physical state of
the device, but is used by some taperscan algorithms to minimize searching through the slots.
Amtape uses the default changer. To use a different changer, use the config override option, e.g., -otpchanger=otherchanger.
SUBCOMMANDS
label label
Search for and load the Amanda tape with label [label], also setting the current slot.
slot slot
Load the volume in the given slot, also setting the current slot. The slot names current, next, first, and last have special meaning.
current
Shorthand for slot current.
inventory
Show the contents of all slots, based on the changer's cached metadata. This is a quick operation as it does not load or unload any
volumes, but is not supported by all changers.
show [slots]
Show the contents of all slots (or listed slots) by loading each slot and reading its label. This can be very slow. The slots arguments
is of the form 1,3-5,7.
reset
Reset the changer to a known state. This subcommand is intended to clear any unknown and potentially incorrect state the changer may
have stored.
eject [drive]
Eject the tape currently in the drive. This only applies to some changers. Specify a drive (by drive number) if more than one drive is
available.
clean [drive]
If a cleaning tape is defined for the changer, used it to clean the specified drive. The [drive] is optional if the changer only has
one drive.
taper
Run the taperscan algorithm (see amanda-taperscan(7)), displaying information about the progress of the scan.
update [what]
Update changer state. Consult amanda-changers(7) for changer-specific details on the format of what.
-o configoption
See the "CONFIGURATION OVERRIDE" section in amanda(8).
