The result is the script I wrote for backing up files to the S3 bucket.īelow is the full, detailed explanation. This is especially true if you want to archive data and don't touch it too often. 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.

Use amazon s3 as personal backup
