Would tape still address the length of time it would take to create the full?
It only takes a few minutes to write 24GB to tape.
Terabyte. Not gigiabytes.
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.

Why is the backup SO large?
-
Total space for our current server fleet (all inclusive,
drives and shares) is almost 6TB.So in trying to create a reliable way to backup everything, in full and hold it for a month we'd need 24TB of space. Cycled monthly. Ideally I'd like to avoid having to go through 100 or 200 tapes.
Even 10 seems like a lot to manage.
-
1 Tape per week that can hold 8TB (for growth) of space by it's self would be a good option. But do they exist? I'm inexperienced with tape backup solutions.

Because he's only using the tapes for full backups, done weekly.
The incrementals would all be local backup storage only.

Nope, you are quite far outside of the single tape size range.
-
LTO 6 can store 6.25 TB uncompressed.
-
Assuming you went with a tape solution, could you dump the backup storage server at the remote site?

That doesn't explain why they need 22TB of total backup, though. I know companies twice that size that need like a few hundred GB total backup.
