I'm still preparing to migrate my media apps and library to a new dedicated machine, but I'm in the old pitfall of having a larger library than I have the means to back it all up to. It's just media, it falls below my threshold for needing a backup, and I don't have the budget for another 60TB to move it to. I do plan to wipe these drives because I will be re-configuring them and leaving them as-is has its own drawbacks. I can back up around 8-10TB on other drives, while needing to replace the other 45TB-ish, so that's what I'll be working with. I'd like to back up what won't be available, and will accept the rest will just require time. I expect at least 90% will be available, but I do have a good mix of items released long before any of the retention policies on servers I'm subbed to.
Are there any arrs, scripts, or other tools already floating around that can scan my libraries and determine what is still available on the indexers and servers I have access to? I simply have too large of a library to do this manually.
Worst case, and what I'll be preparing for until I hear a better solution, is to start backup up anything released before these retention policies, probably moving from earliest to most recent.
