1000x1024mb is.

Why rclone? S3 sync the files on a schedule, enable versioning for immutability and encrypt at the bucket level.

You can always trunk 1g connections together. I picked up an old Cisco 3760G poe+ for 20 bucks at the gov surp. Port channels ahoy!

Pre-seed your backup location and then hope that your change rate is small enough to fit into 10 mb. For example, if you’re using AWS you can get a snowball to load data into S3.

I do an s3 sync every five minutes of my important files to a versioned bucket in AWS, with S3-IA and glacier instant retrieval policies, depending on directory. This also doubles as my Dropbox replacement, and I use S3 explorer to view/sync from my phone.
