Checking file integrity after data copy from box to drive or viceversa

[ncw (Nick Craig-Wood)]

I therefore propose an enhancement to rclone check to automatically do a single- or double-sided download with local hash calculation when remote hashes are incompatible/unsupported.

As an example (think Box/OneDrive compared to GoogleDrive):

rclone check SHA1remote: MD5remote:

rclone check has the --download flag which covers the double sided flag.

I think you are proposing a --download-first flag so when you did

rclone check --dowload-first SHA1remote: MD5remote:

It would download the SHA1Remote files to calculate their MD5.

That is certainly possible.

@Ole

I haven’t checked, but I guess it will be relatively easy to implement since rclone seems to have all the building blocks needed.

This would be reasonably easy to add. The code is in fs/operations/check.go if you are interested in taking a look
