I use it for one of my branch locations instead of going to tape etc. It's about 200GB data with ~2GB or so each night incramental after Veeam is done doing its magic. Not a huge backup but kid of on the same level as you.
We use SingleHop as a provider and they have been absolutely awesome. They seem to have a good compression/dedupe ratio too. I keep 7 restore points, a weekly and a monthly full in their repository and am only using 90GB. I need to find more stuff to push out there! Best part is my 1TB cloud repository is only ~$109 a month, super affordable. They have multiple data centers around the US and over seas. https://www.singlehop.com/managed-hosti ... ions/baas/
Whatever vendor you go with be sure to sign up for a trial and test restore speeds etc. I picked the best I could find.
Just a side note, with V9 you can also use them (or any V9 cloud provider that supports it) as a replication point for DR at a pretty affordable rate....
I think cKent's issue is with the provider, i'd be raising hell if I was down for 4-6 weeks. I did have 2 issues with my backups in the beginning and it was settings that had to be tweaked on the provider side, each was resolved in under 24 hours. But, that is the importance of a full blown demo/trial run before you buy. Most providers will give you 2-3 TB to play with and make sure it works as expected (mine did).
Any other questions be sure to let me know.
