yep, I know, incremental back-ups are deriguer- however, he needs on site=
=20
storage while he offloads to a remote site, AFAIK, the Promise IDE raid=20
drivers are in the stock Linux Kernels as of 2.4.18 or so, I would expect=
=20
(maybe?) they are in the PPC versions as well.

depending on his pipe, it could take hours and or days to do a full back-=
up, a=20
local back-up holding the data on a mirrored raid is cheap insurance - 80=
 gig=20
Seagate cudas are on sale for 110.00 over the net right now.

Standard practice, for those who can, is Raid Level 5 with incremental da=
ily=20
back-ups to tape, followed by a monthly complete back-up to tape. Also, o=
ne=20
should make a separate snapshot (if customized install) - a sort of "froz=
en=20
known state"
--=20
