Recover Previous Recordings

I have a Mac mini that I use for the DVR Service with a Synology NAS for the storage, everything was working well until I decided to do a clean install of MacOS due to a EFI issue when upgrading to Big Sur.

I reinstalled the server software, setting up to the same set up before hand, It won't load the previously recorded content. ive gone ahead and ive added a new season pass for a previous show, it will record into the same folder, yet won't show any airings before the recreated the season pass.

any advice?

Did you restore from backup?

No, I didnt and I didnt make a backup.

Channels automatically makes regular backups. Check the Database folder where you have Channels set to keep its DVR files.
