/vaultwarden backup is going to /root/data not /data

[bwbuhse]

Hi, I'm trying to set up Vaultwarden and I want to make sure backups are working before I commit.

I'm using incus instead of docker compose or podman, but the OCI container seems to be working fine and I was able to create my account & import my data from Bitwarden proper. I try to backup with

$ incus exec vaultwarden -- /vaultwarden backup
Backup to 'data/db_20250821_151127.sqlite3' was successful

but then the backup is /root/data within the container, not my mounted /data volume. Any clue what could be going on?
