Check with the Symantec/Veritas site, they have a plugin for NetBackup 6 that will backup a Virtual Machine by creating a snapshot, backing up the disk file, then releasing the snap. The problem with doing it that way of course is that you don't get the ability to restore a single file. Just like you can use TSIM or TEIM to back SQL or Exchange up, but you are stuck restoring the entire database and not just an individual email. Jg Hey Steve.

I don't know what are the practices in scaling File IO ... maybe I'm way off the mark on this anyway. about backing up vmware virtual machines, often time you need to back up the virtual disk that is 2GB, 4GB, 8GB. I'm no storage guy, what's the practice of backing up large files? ... without v-machine down? hot-backup, any ways? these virtual machines has large File IO needs, most likely network thruput is not the bottleneck, the OS + the resource manager is, don’t you think?

Actually the funny part is I'm not even seeing the gigabit link pushed to anything close to it's max, and that's, right now, with 8 VM's on the box, all but two of which are running solely from NFS. :) (one is blended, with the root on the internal disks, and the data partition on the NFS, and one is internal disks only.)

One word....UGLY. It's not fast by any stretch of the imagination, though I imagine that can be improved upon by putting more beef behind the nfs server, perhaps bundling the links, etc. Until he answers, I can provide a bit of info as I’ve got a rather large test environment that at one point utilized NFS.

Are you able to send me some info? Very interested in building a cheap ESX/VI3 lab using NFS or iSCSI. regards, kaneda Sangod,
