But then I remembered that I work on AWS, and Amazon S3 storage is cheap. Looking for personal cloud backup solutions, I found some overcomplicated, some expensive, and one or two reasonable services.

This, however, is just one copy kept right next to my laptop. I have an external disk with documents and photos archive. On the internet, you can find a 3-2-1 backup strategy: The question about the personal backup system is raised from time to time on Hacker News. But I already had the script, I had fun writing it, I will continue using it, so I decided to share it. Then I did the research again, and the results were quite different – this time, I found a few reasonable services I could use. So I wrote down the backup script myself. There must be a good, easy-to-use cloud backup service, right? But everything I found was too complex and/or expensive.

Instead of reinventing the wheel, I started with research. And it costs me only $3.70 per TiB per month. After some fine-tuning and solving a bunch of edge-cases, it’s limited mainly by the disk read and my internet upload speed. In need to backup my personal files in the cloud, I wrote a script that archives the data into the Amazon S3 bucket. Backup from Google Photos (and similar).
