How to setup auto bitwarden/vaultwarden backup to Rclone Remote in VPS

NOTE: This guide is made from ubuntu vps so username is ubuntu.

I use Arch, btw.

Script i made will do daily backup and keep specified older copy (rentention day is limit of copy to keep) i also made it to upload latest one with date and 2nd copy with "latest" in end instead of date. This is for 2 reason

1. when every you want to find latest backup, it is easy to find. don't have to check date
2. if my rentention logic is buggy and may delete all dates, we ensure that latest one stays

NOTE: i will highly recommand you to use rclone remote so you won't loss if vps gone TIP : if you use it in android device or locally and your PC(window wsl also got way to have cronjob runs. if setup auto-start). use rclone localdisk as remote

WARN : edit code as your liking but keep export format to "encrypted_json". so your data stay safe (specify "--password " in export command if want custom password to encrypt it instead of vault master password)

1. Install Bitwarden CLI using npm npm install -g @bitwarden/cli

2. Specify custom host for bitwarden using bw config server url eg.

bw config server  https://bitwarden.garudalinux.org

3. Run bw login and login by entering email and password (2FA code also if you have one, good if you do)

4. Run bw unlock --raw, and copy session string.

without "--raw" you will get message that vault is unlocked and now you can use it + it will give you code to set env for session and tell how to use in "--session" NOTE : Session string is valid for specific time, i don't know how long it is, but do check log file to ensure it is not expired you could specify your master password directly in command in script, but it is not good idea to do so.

5. Edit config variable

6. Setup cronjob (specify your path)
