With cron you can automate pretty much anything you can write a script for. That includes sending files around.
how much data?
I have found and testet on digitalocean.com Works great.
but have little memory capacity, because ssd.
how much need it for this page?, and what do you advise me?
Not much.. though over time it does increase, since the actual post data takes up space in memory.
A forum like this (running Redis) could last 2-3 years on the lowest digital ocean plan. Indefinitely if you use Mongo, since its data is persisted to disk.
O nice, thanks for this Information. i was really confused about this offer on digitalocean.com.
@julian Out of interest, has anyone calculated how many posts/users redis with 512mb of RAM could theoretically handle?
