This script syncs a local Hyper Backup destination to Google Cloud Storage Nearline on a Synology running DSM 6.0 or greater. The script will check to see if Hyper Backup is idle, and if it is, rsync the Hyper Backup destination to Nearline.
Create a new share on your Synology to serve as the local Hyper Backup destination. It will also store the Nearline scripts.
SSH into your Synology, run sudo su -, and cd to your newly created share. Create a new directory named nearline and cd to it.

Using DSM, install Hyper Backup and configure a local backup to a subfolder of the share created earlier. Then, go to Control Panel > Task Scheduler and click Create > Scheduled Task > User-defined Script. Ensure the task is set to run as root. Use the following command:
NEARLINE_HOME=/path/to/nearline bash -c 'flock -n $NEARLINE_HOME/nearline-upload.lockfile -c "$NEARLINE_HOME/nearline-upload.sh /path/to/hyper/backup/destination gs://path/to/nearline/bucket >> $NEARLINE_HOME/nearline-upload.log"'
