Where are logs and backups related to upgrades stored?
Each time Nodegrid OS is upgraded, it creates a backup of the configuration and a log of the upgrade progress. Those are stored in /var/upgradeBackup. The configuration backup will be named config- followed by the version with the .tgz extension; for example config-5.0.6.tgz. The upgrade log will be named image_install. followed by the date and time in numeric formal; for example image_install.20220324_215056.
