When you have versioning turned on in a Backblaze B2 cloud storage bucket (always on for 1 day minimum) you can restore deleted objects by finding and deleting the "delete/hide markers" to restore the old version. This script makes that easy and fast.
Usage:
b2 authorize-accountbash b2-restore.sh <bucket> <prefix>
