# Kindie — one-command backup script (Linux)
#
# Backs up the database and, if it exists, the local uploads folder —
# everything you need to restore this installation elsewhere.
#
# Setup (once):
#   1. Save this file as backup-kindie.sh next to your Kindie installation
#      (or anywhere — just fix KINDIE_DIR below).
#   2. chmod +x backup-kindie.sh
#   3. Edit the settings below to match your install.
#   4. Try it once by hand:  ./backup-kindie.sh
#   5. Schedule it (daily at 2:30am, keeping the last 14 backups):
#        crontab -e
#        30 2 * * * /path/to/backup-kindie.sh >> /var/log/kindie-backup.log 2>&1
#
# Requires mongodump — see "Linux Installation" (mongodb-database-tools)
# in the Kindie user guide if it's not installed yet.
