Thanks for taking the time to respond.
To be clear, my entire array wasn't effected, only my Movie share. The torrent didn't have a path, I didn't select "don't add torrents name to path", it just so happened to contain a single file. Fortunately my TV and Music shares are separated into their own shares so those remain intact.
In the future, I am absolutely going to disable the delete all option; for my own utilization, I can't imagine a practical use case where the delete all accomplishes anything that the regular Delete Data option wouldn't.
As per your suggestions:
1. I plan to keep torrents seeding long term so my cache really only pulls duty for appdata.
2. Disabled
3. Looking at my plexpy data, 1710 movies got wiped (ouch) but I have ~980 of them backed up on a remote server; I have started the 3.5 mb/s slog to recover those and the others will be recovered over time. I resorted to taking screen shots of my plexpy library data so I can have a list of files; don't want to miss any on my rebuild. I think I will end up biting the bullet and building a local back up because rebuilding from a remote server is a bit ridiculous at my download speeds lol.
4. I use CA backup but I'm not sure what good it would do me for recovering my plex metadata since I will slowly rebuild my library with new additions sprinkled in. So any time I refresh my plex library, they will get cleaned out; I think it will be the least hassle to rebuild bit by bit.
