Thanks to a pretty good sale at Western Digital, I recently upgraded a bunch of older 6 and 8TB hard drives to 16TB drives, giving me room for future expansion. In the process, I had to transfer my library files to the new drives and then make sure the network shares / top level folder names all matched before starting JRiver back up. Unfortunately, I screwed up a couple of the shares and didn't notice my screw up for a few days. For the most part, it's no big deal because the sidecar files were alongside the files and repopulated my metadata once JRiver found everything again. So ripped movies and individual TV show files are all fine.
Unfortunately, the same can't be said for particles, so all the work I had put in to breaking some TV series Bluray rips up into particles for each season/episode was lost. I can't revert to a library backup prior to my screw up because I'm pretty sure that all of my TV recordings that happened since won't be brought in as JRiver TV recordings.
I can get past having to split these up into particles again, despite it being a non-trivial amount of work. Fortunately, I didn't do this with my entire collection, so it's only a few seasons of a few shows.
Is there any provision for saving copies of particles to prevent this sort of screw up from having the same end result again? I'm thinking a way to save each particle as a sidecar file as one possibility; I don't recall seeing an option for that anywhere.
