The TF2 community has been going strong! There’s even been a revitalization of classic custom game modes like TFWare, Balloon race, Dodgeball, Smash Bros, Randomizer, Class Wars, etc: https://teamwork.tf/community/quickplay

I use Duplicati for my backups, and have backup retention set up like this:

Save one backup each day for the past week, then save one each week for the past month, then save one each month for the past year.

That way I have granual backups for anything recent, and the further back in the past you go the less frequent the backups are to save space
