Availability

I keep these services secure and running well because I heavily rely on them. I would be the most impacted if anything broke down.

I have a hybrid setup with most services running out of my house and some hosted on a VPS (virtual Private Server) at Hetzner. This rarely happens, but if power or internet goes down at the house, services running from my house will be offline during such time. Sometimes I need to do maintenance and reboot the server which can cause a brief outage.

I have a 3/2/1 backup strategy done nightly. I also have an extra backup server and hard drives available if any hardware fails. Although unlikely, if some disaster happens to the house or me, services could be offline indefinitely. I recommend that you have local backup of any critical data you need. For example, if you use Nextcloud, sync files to your PC or handset with the Nextcloud app.

Unlike corporate platforms, these services are free and do not lock you in. With the inbuilt tools, you can rather easily migrate most accounts and data to another instance if/when desired. The steps are different depending on the service, and I will help you.

I cannot guarantee all of these services will be maintained forever but neither can corporations promise the same. https://killedbygoogle.com/ In my experience, these free projects running on our server are more durable.
