Dropbox and --checksum

[alexelcu (Alex N.)]

Hello,

In the Dropbox documentation it says that Dropbox supports its own “hash type which is checked for all transfers”.

I want to do an “rclone sync dropbox: local/path” a second time to ensure that the previously copied files haven’t been corrupted.

Do I need to use --checksum for it? Asking because it seems that using --checksum takes an incredibly long time and it is my impression that all files are re-downloaded from Dropbox again when I’m doing it.

No you don’t need to use checksum - rclone will check the modification times if you don’t.

That shouldn’t be the case!
