I’m looking into using Rclone for personal backup with B2 integration. I’m wondering how the rclone copy command detects that a particular file is already uploaded; or if an
uploaded file has changed? Does it send a query to the server or is this information cached internally? This is important, because B2 is charging for transactions and AFAIK retrieving information about a file is a transaction. If I have many files and want to sync often I will be charged even if no files have actually changed!
Regardless, this looks like a great tool!
