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.
