Yes, true in both accounts. I'm not even sure at this point how it will be presented so journaling might not be an option, unless something has changed. The way they are currently presented from the device they are using makes it impossible to use it. Restoring, and I have seen the 700GB luns take forever when someone has mistakenly blown them up here...don't ask...so I don't even want to be here if that happens. Well, actually I won't so why would I even worry. Geoff TwoThumbs BB......

Actually, I think TSM is the only thing that will be able to backup such a thing. Incremental forever is the only way. Put Journaling on and it gets done. Now, that's backup. Forget restoring it! That won't happen in any reasonable amount of time now will it? Kelly Lipp Chief Technology Officer www.storserver.com 719-266-8777 x7105 STORServer solves your data backup challenges.

Sent: Wednesday, May 26, 2010 5:04 PM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] why create a 12TB LUN I'm guessing many of you will find this quite odd, I know I did, but I had someone come to me and say they were going to ask for a 12TB LUN and wanted to back it up. Without even mentioning the product they want to use, obviously not TSM though, and I'm not even sure it would make difference, how would you manage to get a 12TB LUN backed up daily. I would expect it to be at least 75% full if not more, and even without knowing what percentage of data changes on it, it would seem to me the request seems strange. They're thinking of getting a VTL and backing up through fiber direct, not across the network, but no idea which one or what sort of throughput to expect. Have any of you been approached with this sort of request and if so what was your response? I'm sort of dumbfounded at this point since I've not heard or seen this anywhere.
