Backup Jenkins to S3

This way we will backup all except for SCM folders and jars. All Jenkins configs, jobs, logs and builds will be preserved, only built artifacts will be skipped

Backup command:
export GZIP=-9 && tar czfh - /var/lib/jenkins/ --exclude-vcs --exclude "archive" --exclude "target" --exclude "/var/lib/jenkins/docker" --exclude "/var/lib/jenkins/.m2/repository" | /usr/local/bin/aws s3 --region us-west-2 cp - s3://<bucket_name>/jenkins-backup.tar

 Restore command:
aws s3 cp s3://confyrm-jenkins-backups/jenkins-backup.tar - | tar -C / -zxf -
