Same thing happened to me. Posted here and here but no replies:
I haven’t found any way to access the backup files or do a database repair on a MyCloud Home. Also looked into a way to export the playlist list but was also unsuccessful. Which is quite a bummer as I put a lot of time into those playlists!
I find it quite concerning that we can’y seem to access the backup database. I have thought about trying to change the path of the back up? what do you think?
Interesting thought. Doesn’t help our current problem with apparently corrupted playlists but would be nice to have for the future if it happened again. Not sure how you would go about changing that path though?
