Netbackup and Equi-Logic SAN
Hi,
We are purchasing a Dell equi-logic SAN (6100) for our VMware environment. We used to do NFS for the datastores but we will need to move to a block device. The problem becomes I need a solution using Netbackup 7.5.0.4. It looks like an offhost backup may work but I was wondering if anyone has any info on how I might go about doing this. Do I need to set up a windows server that can talk to the SAN and use him to mount the volumes from the SAN? Can I do it using a Linux box? The reason I ask is our master /media server (we have one) is Linux 5.x. If someone can point me in the right direction, I would appreciate it. Thanks!

Don,
Thank you !
OK I see what you are saying. Just a little background, we currently use NFS for VMware datastore connections so everything is file based and we do "backups" or to tape using replicated snapshotsto our DR site. We keep snaps for near storage restores of virtual machines. Those production volume are then replicated to the DR site and then taken to tape from there. Our Netbackup Master /media server is Linux so nfs is very convenient.
What you suggest is exactly what we do except we use the replicated volumes so we don't hit the production spindles.. Could I mount the replicated EQL snapshot and put that off to tape? We are getting two systems, production and DR.

Don,
Sorry for so many questions but I haven't even seen the EQL software yet still trying to work out backup. So by using some scripting, I could mount the snapshot on the backup server using vmfs-tools and then put it on tape. A backup to tape from a snapshot would then be running on the production spindles. My big concern is how will that impact overall VM performance during backup. We plan on going 10 Gb network.

Hi,
So a snapshot would work but that is on the prod spindles. I would have to clone to take it off to tape. That also means I need enough room to replicate and clone for backup (removed when done, netbackup pre and post triggers). When doing snapshots, is that at the machine level or at a volume level or can it be both? I would assume that cloning only works at the VM level. That means I could only do clone backups one machine at a time, not as a volume snapshot with VMs quiesced. Would that be true.
Thanks much!

Don,
Totally understand that. It goes to tape just in case the planes hit both our production and colo sites. It's just peace of mind.
And it will allow us to us 10 GB for backups.
Thanks very much!
