There are two directories to backup Gemfast:
/var/gemfast- all data including gems, database, etc.
/etc/gemfast- configuration data
It is recommended to create periodic backups by compressing and moving these two folders to an off-server location like Amazon S3 or similar.
sudo tar czf "gemfast_backup_$(date +%s).tar.gz" /var/gemfast /etc/gemfast
Restoring From a Backup
To restore from a backup, unpack the backed up folders to their original locations and start up the Gemfast server.
tar xvf gemfast_backup_1689105521.tar.gz sudo mv ./var/gemfast /var/ sudo mv ./etc/gemfast /etc/ sudo systemctl restart gemfast.service
