therefore we decided to re-install the forum with an automatic back up from several hours back.
How can you do this automaticly? I am using redis and I have to copy dump.rdb manually.
As just mentioned, mongodb is backed up and the archive is compressed via cron, then sent to an external volume. The older ones also deleted periodically again via cron. Redis is used for sessions.
I am looking into the option of taking multiple snapshots in a day via digitalocean API's to replace this system though. I did this succesfully for the data volumes however I have yet to come up with a way to do the same for the droplet itself as i don't see any digitalocean API for that.
