Full Discussion: backup the whole system to a usb disk.

it depends on the configuration...

if you have raw slices for the OS, then ufsdump is the best.

If you have Veritas Filesystem for the database then it could be possible to clone the veritas filesystems, umount the original filesystems, mount the cloned filesystems, and when you roll back just mount back the old filesystems. but depends obviously if you have available space.
If not vxdump would do the job if you have vxfs over veritas volume manager, if you have ufs over veritas volume manager then we can use ufsdump as well...

Feel free to IM me, I sent the details by PM.

cheers

local-filesystems

local-filesystems(7)					 Miscellaneous Information Manual				      local-filesystems(7)

NAME

       local-filesystems - event signalling that local filesystems have been mounted

SYNOPSIS

       local-filesystems [ENV]...

DESCRIPTION

       The  local-filesystems  event  is generated by the mountall(8) daemon after it has mounted all local filesystems listed in fstab(5).  moun-
       tall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with  other
       activity.

       This event is typically used by services that must be started in order for remote filesystems, if any, to be activated.	Remember that some
       users may not consider it wrong to place /usr on a remote filesystem.  For most normal services the filesystem(7) event is sufficient.

       This event will never occur before the virtual-filesystems(7) event.

EXAMPLE

       A service that wishes to be running once local filesystems are mounted might use:

	      start on local-filesystems

SEE ALSO

       mounting(7) mounted(7) virtual-filesystems(7) remote-filesystems(7) all-swaps(7) filesystem(7)
