BackiGo review
A still frame of a birthday toast can look exactly right and still leave out the clink of the glasses. BackiGo is useful if you want a copy of the Live Photos in a personal album that you can bring back into Apple Photos with their motion and sound. The Live Photo backup and restore features require BackiGo Pro.
Back up a small album to a drive
On the Home screen, open “Connection Status” and add the external drive as a backup destination. Start a backup and pick a few Live Photos from the album. I’d check “History” before unplugging the drive and retry any items marked as failed.
Restore a few shots and play them back
Choose “Restore Backup” and then “Restore Photos”. Pick the backup and the shots you want, then choose where to restore them. I’d put the trial restore in a separate album and open it in Apple Photos so I can check that the motion plays and the sound comes through. For a gallery of stills to share afterwards, Pic-Time is a separate option.
Anabel’s take
I’d do this with a few family photos before trusting it with a whole album. I’d keep the originals and a second copy of anything I couldn’t reshoot, even after the first restore works.
