Backup to S3 scriptīelow is the full, detailed explanation. The result is the script I wrote for backing up files to the S3 bucket. 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.

You can get the instructions to set up the extended version history here. You can choose 1-year of retention or forever. If for any reason the Backblaze data center has not heard from your computer after six months, the backup copy of your data may be removed from the Backblaze data center and your account is subject to cancellation.īackblaze does have an extended version history feature, that will allow you to bypass the 30-day limit that was discussed above. In addition, Backblaze must continue running on your computer to perform self-maintenance and maintain the correct mirror copy of your files in the Backblaze datacenter on an ongoing basis. So, please don’t try to upload your external hard drive to us and delete your data off your drive…or we will delete those files from our servers as well. However, Backblaze is not designed as an additional storage system when you run out of space. Just in case, Backblaze will even keep multiple versions of that file for up to 30 days by default. Thus, we will keep a remote backup of any file that exists on your computer. The Backblaze service is designed to protect the files you care about.
