I will look into iSCSI - although i have never worked with it.
Basically here is what I have to work with:
I have a linux pc running gentoo with kernel 2.6 and backuppc but this machine does not have enough space for my backups.
i have a windwos 2000 server with 250GB raid 5 array, and I can use this for storage. currently the only way i know how to setup raid 5 is with mdadm, and im not too keen on formatting the windows pc and putting gentoo on it, becuase for me it is easier to rebuild and administer the raid when it is on windows - especially something as critical as a backup server. I dont want to sit and battle with the os and the raid, so far it' stable on windwos and i want to keep it that way - if this is possible
so now I have a windows box with space and a linux box with backuppc - (the program i love and trust)
thats my problem:
so all i need is for backuppc to be happily using the windows box's space for a storage medium - nfs like you say will give me nightmares but thats the only way i read and knew about, i will try iSCSI and post back to the list for help -
if anyone on this list have any examples or advice, i will apreciate that very much,
thank you your help and support,
winston

Are you 100% sure you want to do this? I think it's a recipe for
disaster on 2 counts. First I have played with SFU (which Microsoft has
stopped developping btw), mostly with the nfs client and it is horrible.
Slow transfers, timeouts and all sorts of trouble. Maybe the nfs server
is better, but don't count on it. I would only use that for emergencies.
Secondly: I think it's very dangerous to use nfs in this situation,
especially if more than one backup is running at the same time. NFS
semantics are close to unix semantics but not quite. For instance: it
can take up to 30 seconds before a newly created file is visible to all
clients. And there are several more gotcha's.
So to summarize: nfs in windows is not so good (maybe better with
cygwin) and I think nfs is the wrong tool for the job.
What I would do is export the windows partition you want to put backuppc
on with iSCSI and import it on your backuppc server. You don't need the
shared access of NFS, because backuppc will be the only client, and with
iSCSI you get blocklevel access to the partition (it's now a local
device to the backuppc server) so you can put any filesystem on it you
want. And iSCSI is much faster than NFS. Especially on a gigabit
interconnect. All the software you need on Windows is downloadable from
Microsoft and is available for every Linux distribution. You do need a
fairly recent 2.6 kernel.

Forget about nfs and try iscsi, you'll be glad you did.
