Re: [PLUG] epiphany or stupidity?

Not the most useful, but going to just flop this out there:

De-dupe, netboot, etc. It all comes down to how you're doing the backups, what they are/aren't encrypted or compressed, if dedupe could be done at the storage or disk level, etc.

If you're nfs-booting, and the root are essentially the same, you get that benefit easily thanks to the SAN, but... in circles of implementation questions we will go.

I was running last night, and for some reason, I had an idea about backups. It occurred to me that if I had 100 Red Hat systems, all running the same OS and Patch level, would I need full backups on all the systems. Wouldn't there be static information like executables that would be the same across all systems? So instead of doing fulls x 100, I could do a full x 1, then just differentials or incrementals on the others, thereby reducing total storage required on tapes.

Then I thought if I took the same idea and applied it to the SAN storage, could I have fixed images that the systems run on, and only require 1 instance of it, thereby reducing total storage space requirements.

Then I thought, either this is a really stupid idea, or it's brilliant and most likely already done.

Comments?

Thanks,
