Borg Backup for Container Config

Install latest release of  https://www.borgbackup.org/ from https://github.com/borgbackup/borg/releases   
 
 
 custom backup scripts to backup container configs from /etc/svc/config/${APPNAME}  
 
 
 1. Initialization of backups 
 
 create a new borg repository locally in /dev/shm/${APPNAME} 
 Create a new github repository under pknw1-config/borg-${APPNAME}  
 Push the base files as the initial commit 
 
 export APPNAME=bookstack
export CONF_FOLDER=/etc/svc/config/${APPNAME}
borg repo-create --encryption repokey-aes-ocb -r /dev/shm/${APPNAME}
gh repo create pknw1-config/borg-${APPNAME} --private
cd /dev/shm/${APPNAME}
git init && git add . && git commit -m "init" && git branch -M main && git remote add origin git@github.com:pknw1-config/borg-${APPNAME}.git && git push -u origin main
 
 
 create an initial backup 
 
 borg -p -r /dev/shm/${APPNAME} create ${APPNAME} -e '*MediaCover*' -e '*Logs*' -e '*logs*' -e '*Backups*' -e '*cache*' -e 'metadata' --stats "init" ${CONF_FOLDER} 
 2. Regular Backups

 Using the backup script borg-docker-auto.sh ${APPNAME} will 
 
 find all running containers under the app project and docker stop each container 
 if /dev/shm/${APPNAME} doesnt exist, it will clone the remote repo pknw1-config/borg-${APPNAME} is cloned locally 
 a nw git branch is created 
 borg backup from /etc/svc/config/${APPNAME} is done to the folder 
 all files are git add , git commit and git push to the new branch 
 each of the stopped containers are re-restarted with docker start
