You can only keep one directory of your storage. What folder do you pick?
Not the top level directory, obviously.
For me, it would be my Camera directory. Worst case scenario would be to part ways with all the photos and videos I took for 15+ years, including the digital versions of a few hundred objects.
On my server I would keep /NAS/Photos.
Sure I’m loosing 45TB of everything else, but all my photos are stored in there. Some are irreplaceable, and sure they’re backed up, but I read the question as “you loose everything except the one folder”. So if I lost all my backups, Photos is the only one that would be devastating.
