If I could figure out how to do it ...
When you do, make sure you turn on the numbering option in the last four columns. It really helps if they get out of sequence.
I once dropped a large, un-numbered deck of cards. Never did that again!
PS Back on topic.
Another vote for Backblaze. The beauty of this system is that it runs automatically in the background, so backups are always up to date, unlike my local disk backups, which I typically run weekly.
Another feature of Backblaze is that I can access my files via the web, using any computer.
