Master/Media : Solaris 9 with NBU 5.1.
Client : Win2K / Win2003.
Storage : EMC Clariion / IBM ESS.
Hi all, we have got a couple of Windows fileservers of around 1.5 Tb
(which is a lot of data for us, at least in terms of the time taken to
back up...)
We have had some success with Solaris & Oracle, using Advanced Client to
backup offhost (media server) with Vxfs / nbu_snap snapshots and I would
like to do the same sort of thing for our Windows clients. However, the
options seem to be more limited, i.e. to FlashSnap and offhost/alternate
client. I am not sure this would get the data off the network and onto
the fibre or how relevant FlashSnap would be for us.
What sort of things do other people do to back up large Windows boxes?
At present I have to use file lists to attempt to split the drives into
multiple streams, and in general all the data is on one drive and hence
going to one tape drive. I know this means that with LTO2 I *should* be
able to get this down to around 10 hours, but this isn't happening
(network/client server size limitations I think), and anyway as the
servers grow it will become worse. I am trying to look across the board
to see the best way of doing this, and struggling a bit as I am a UNIX
person...
Ideally I would like to
o use some snapshot technology to potentially keep backup images for
restore
o transfer data over the fibre rather than network
o remove load from the client
o split the backup more sensibly i.e. without being limited to the
drive letters
(o and reduce the amount of data ... but that's another discussion!)
thanks for any suggestions,
regards, Phil
