The bandwidth is limited to 10 Mbit/s upstream and downstream.
Still, it's good to have a cheap offsite backup to complement a local one.
10TB == 10,000GB == 10,000,000MB
10Mbit == 1.25MB
10000000/(1.25 * 60 * 60 * 24) = 92.6 days
Time to upload is probably not a problem, you gradually add to it over time. Time to download all the data in the event of a disaster is the bigger issue. There aren't a lot of use cases where you'd need all the data back ASAP but if you have such a case, don't rent this storage.
Upload speed: 1.4MB/s. Close to my maximum of 1.6MB/s.
Download speed: 1.3MB/s. Far from my maximum of 15MB/s.
This could be good for NAS backups.
I agree, offsite back up of local storage is a good use case.
