Description

It would be great to have an environment variable that adds different directories to the backup, so I can back up other directories besides the /data directory.

For example, I want to back up my patches in the /patches directory and /data, which I don't think is currently easy to do.

Contributor guide

Research direction
Examine the existing backup script (e.g., backup.sh) and Dockerfile to understand how directories are currently backed up. Add logic to read a new environment variable (e.g., ADDITIONAL BACKUP DIRS) and include those directories in the backup archive.
