Google is not your friend, it’s a tool.
[…]consider that Google can shut you out of all their services with no recourse or appeal possible. All your data, photos, calendars, emails… gone.
But yes, you can back up your data. Do it today…
– Today is Worldwide Backup Day - Seth’s Blog
An important reminder. And this doesn’t just apply to Google. Regularly export your data from other social networks and online services, because they will never care about your data as much as you will. Even if caring about your data is their job.
(For that matter, I should even be periodically backing up this stream, because it’s hosted on micro.blog, not my own servers…)
