Rsync can. For instance, rename files instead of deleting them, so that your backup keeps old files in case they need recovering.

It can also make hard links to existing files so they you can create multiple backup directories that share unchanged files to save space.

I was wrong to think that, I tested bitwarden Android client in airplane mode and it worked, but I didn’t realize that had a “signed-in” state separate from unlocking the vault with the password.

The Bitwarden client works offline, syncing the database locally when online. So won’t that also happen with vaultwarden? Everyone would still have access to what was last synced.
