Why did files I deleted in one place disappear from the other after a sync?

\n

Short answer: Syncs carry deletions: one-way sync removes destination files no longer in the source, and Bidirectional sync deletes in both directions. Use Copy for an archive that only grows, or Data Backup to recover deleted files.

\n

That's how syncs keep two places matching. Sync (one-way) removes files from the destination that are no longer in the source, and Bidirectional sync carries deletions in both directions. So deleting a file on one side means it's deleted on the other at the next run.

\n

If that's not what you want:

\n
  • Use Copy for an archive that only ever gains files.
  • Use Data Backup if you need to get back files you deleted.
  • If the files were in a cloud account, check that service's own trash — many keep deleted files for a while.
