If an upload to the cloud is interrupted, does it start over?

\n

Short answer: Only the file in progress starts again — finished files are skipped on the next run, and server and bucket transfers retry brief drops automatically. Resuming part-way through one file applies only to large downloads.

\n

Only the file that was in the middle of uploading starts again. Files that had already finished are skipped when the transfer runs again, because transfers only send what's missing or changed. Transfers to servers and bucket storage also retry automatically after a brief network drop.

\n

Picking up part-way through one file only applies to large downloads coming to your Mac. For a very large single file going up, a steady connection matters — plug in to power and avoid letting the Mac sleep until it's done.
