IDrive for Mac retains earlier file copies via Snapshots technology. Snapshots are point-in-time images of the file at a particular time, everyday. The current limit for Snapshots is set for 10 days and this may change without notice. This implies that in case you had a prior version that was backed up in the last 10 days, you should be able to recover via Snapshots technology.
