BackUp device for local or colo storage

Oh I excluded it mistakenly, the full backup by my estimates, performed weekly (and held for a month) would total ~24 TB of space. (rounded for drive sizes)
What is the delta rate? That is the most important number.

Is this realistic to even pursue an Off-site backup solution?
Tape. That's how everyone tackles that.
Would tape still address the length of time it would take to create the full?
I can't imagine it would. This isn't for archival but recovery in IT Disaster.

I'm uncertain of how to find out. Any recommendations?

Exactly, if you go incrementals, can't StorageCraft sync via the WAN to another server? Why bother with the fulls?

It only takes a few minutes to write 24GB to tape.

Terabyte. Not gigiabytes.

It has to be measured. You need to see how big incrementals are.

That's what I meant. Tape is fast, very fast.

And how would that operate for off-site? Wouldn't someone have to site there changing tapes in and out?

No, you change the tapes locally. You DRIVE the tapes to the offsite. The entire point is to bypass the WAN. Anything using the WAN is going to be a non-option.

I assume you would find a tape solution that holds a single full backup. Then you just swap the single tape. You said you only do it weekly, so that would be four tapes a month, and someone would have to bring them to the offsite location.
-
So a local tape solution, carried off weekly.
They can't be much heavier than the 22lbs box I take home weekly...

Right, like far less than a pound
-
Wouldn't you carry off daily?
-
Any recommendations on a product that can hold this. I haven't used any tapes in my experience.
-
Do disk to disk to tape. Disk backup kept onsite. Tape taken offsite.
-
Daily incrementals could be performed to a colo (or online storage service) easily enough. It's the fulls that would have to be run weekly.

Any WILL hold it, it just takes more tapes the bigger it gets. You would determine your tape technology choice off of your delta rate, not your full rate.
LTO is the tape technology you would use. Which model, LTO 3, LTO 4 or LTO 5 (or the upcoming LTO 6) would be what you need to choose.
-
You will want an automated tape library, of course.
