After nearly losing a significant portion of my personal data in a PC upgrade that went wrong (gladly recovered everything), I finally decided to implement proper-ish 3-2-1 strategy backups.
My goal is to have an inexpensive (in the sense that I'd like to pay for what I'm actually going to use), maintainable and upgradeable setup.
The data I'm going to back up is are mostly photos, videos and other heavy media content with nostalgic value, and personal projects that are not easy to manage in git (hobby CAD projects, proto/video editing, etc.).
Setup I came up with so far:
-
- On PC side, backups are handled by Duplicati. Not sure how stable/reliable it is long term, but my first impression from it is very positive.
-
- Backups are pushed to SFTP server hosted by Raspberry Pi with Radxa SATA Hat and 4x1TB SSD in RAID5 configuration (mdadm).
-
- On Raspberry Pi, I made a service that watches for a special file pushed by Duplicati post operation script and sync the contents of the SFTP to AWS S3 bucket (S3 Standard-Infrequent Access tier).
Since this is the first time I'm building something like that, I'd like to sanity-check the setup before I fully commit to it.
Any reasons why it may not work in the long term (5-10 years)?
Any better ways to achieve similar functionality without corporate black-box solutions such as Synology?
