BackUp device for local or colo storage
-
So in working on an existing project to update our server fleet we've decided we need to virtualize. It is simply not a choice any more.
With that, I've already built a pretty solid platform it needs a few tweaks. Specifically adding 4(plus the original 8 ) totally ~ 11TB of storage on each host. Duplicate hosts.
The backup device options that I'm trying to figure out now is what's the best way to keep 1 months worth of full Server Backups off site. In a colo or sister location etc and one on-site for "rapid recovery". The full backups from my estimate can take 22 days to run... Is this realistic to even pursue an Off-site backup solution?
30Mbps symmetric Internet service at our main location with approximately 8TB of OS and file storage space across our server fleet.
To summarize I've settles on a Dell R510, 12 Bay 3.5 Drives with Western Digital RE 4TB, in RAID 6.
I would prefer to use RAID 10, but just don't think I can find something reasonably priced for this. I'm expecting to have 2 backup units. One onsite, the other offsite.
This is building backups from XenServer using NAUBackup which creates full snapshots and then pushes them off host to a file server.
In addition to this I need a way to keep hourly incremental changes onsite for 72 hours and then dump them. My boss doesn't want to reuse the equipment we have. So looking for ideas.
Maybe just another R510 server in RAID 6 as well. Total in 3 for backup purposes?
What do you guys think? Be brutal as I really am looking for ideas.

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)
-
Am I correct in understanding that there is no other backups software solution that will create incrementals? That should solve your 30 Mb pipe problem.

Because you don't have incremental technology, right?
Assuming there isn't a third party solution that provides incremental, I wonder if going with Hyper-V would have been better for you and use a backup that provides incremental backups.
The end result would be nearly the same, and sounds like it would actually be better.

Tape. That's how everyone tackles that.

We currently have Storage Craft for the incremental backups as well as Root directory backups.
We would likely continue using it for incrementals. But performing the fulls is what has me the most concerned.
(good point, forgot to add it)

What is the delta rate? That is the most important number.

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
