Can I restore the backups during the free, backups-only period?

Only backups will be supported by the free, backups-only version. Restore capabilities will only be ready with the full, paid version of Rewind Backups for Bitbucket. However, your backup snapshots that were generated with the backup-only version will still be able to be restored by the full version if you switch to a paid plan with full restore capabilities once it is ready.
