Suggestions for best free and open source backup solution for MacOS for mid-2021, Big Sur? It's fine if there is a support agreement and/or cloud storage available. But really would like open source and ability to build myself. For obvious security-related reasons.
I am a software developer, mostly iOS/Android, that might have some influence.

- Windows, Linux desirable but not necessary
- Local storage and S3 destinations, must support non-Amazon destinations (I have Wasabi and IBM Cloud)
- Must take and use a snapshot so backup is possible from a running system
- De-duplication
- Incremental backup
- Able to go back in time
- Great if it can do something intelligent with database files, specifically PostgreSQL, but not essential
- I have concerns about "state" files, e.g. /Library ~/Library, etc. despite my being a dev, I don't have much insight as to what is important to backup there, and what to restore in case of need to do a total restore, so some "guidance" in the app would be great.
- Ability to make a bootable backup, or at least a full backup that might not be bootable (I guess there are issues with Big Sur...) would be great but not necessary. I've used Carbon Copy Cloner in the past (yes, not open source...) but one app for both functions would be great. For this, I plug a big hard drive into a USB "toaster".
