We backup LA, UK, Australia, India, Dubai, Minnesota, Ireland, and Boston and it is about 5 TB-7 TB. We have 3 appliances in remote sites that are larger and 1 big one at our main site.
In our test with 1 remote site this is the timing..rough estimate
TSM it took 2 weeks to backup the data the first time and 1 day for every incremental
PureDisk took 1 week for 1st backup and about 8 hours every incremental
Avamar took 96 hours for 1st backup and 15-30 minutes every incremental
The cost is varied by if you want fast local restores. With our test whatever it took you to backup with client-only based only mutiply that by 2 and that is your restore time. So 96 hours would take about 200 hours for total restore. But it depends on if you need a local appliance or not.
