Will importing the same KeePassXC CSV twice create duplicate entries?

[Cyb3rN3xus]

Hey everyone,

I'm currently using KeePassXC as my primary password manager, but I want to set up Vaultwarden as a secondary backup/syncing solution. My plan is to periodically export my KeePassXC database as a CSV file and import it into Vaultwarden.

I understand that CSV exports don't include unique IDs like JSON exports would. If I import the same CSV file twice (say, initial import today, then another import next month with mostly the same entries plus some new ones), will Vaultwarden:

• Skip entries that already exist in the vault?
• Create duplicate entries for everything?
• Something else entirely?

I want to avoid ending up with hundreds of duplicate logins. Is there a recommended workflow for keeping Vaultwarden in sync with an external KeePassXC database without creating duplicates?

Thanks for any guidance!

There is no way for the server side to check for duplicates.
So if anything, the clients should support this. But i think they do not.
