Keeping self-hosted Bitwarden up to date automatically

I have a self-hosted instance of Bitwarden running on a Debian10 server. What is the best option to keep this up to date? If I use crontab should the following suffice?

0 2 * * 0 /opt/bitwarden/bwdata/scripts/updatebw.sh >/dev/null 2>&1

updatebw.sh

#!/bin/bash
/opt/bitwarden/bitwarden.sh updateself
/opt/bitwarden/bitwarden.sh update

I will also be snapshotting the VM and running bwdata/ backups weekly just before the updates run.

Thanks!
