Discouse neemt veel schijfruimte in beslag, voornamelijk de redis_data map

Take a look at:

Is secure storage for Redis necessary?

Can you define “history” here? Losing the Redis DB (equivalent of redis-cli flushall) is something the Discourse app will recover from without major problems, but you will lose some stuff, like emails that were in a queue, etc. So while it’s not something catastrophic, if you can avoid it without much hassle I’d recommend you to.
