I’m trying to sync a KeePassXC database between my Android phone and my Manjaro Linux system. I want full two-way sync of changes, but I don’t want deletions on one device to remove the file on the other. What’s the best way to configure this? Tools like Syncthing seem close, but I’m not sure which folder settings or ignore rules would prevent deletion sync while still keeping both sides updated. Any guidance or examples would help. Thanks!
What you’re describing is not a two-way sync then. You’re expecting this to be an actual database, but it’s just a flat file with XML at its core. Here’s the file format specification .
Best you can do is set frontend options to prevent accidental deletions, and keep lots of backups, or put it on a versioning storage backend.
You may want to switch to a different solution if this is your desired use-case.
