# This script will backup all mysql databases into
# compressed file named after date, ie: /var/backup/mysql/2024-05-09_07:00.zip

# Setup variables used later

# Create date suffix with "F"ull date format and add hour:time

# Set output dir here. /var/backups/ is used by system,
# so intentionally used /var/backup/ for user backups.

out="$outDir/$suffix.zip"
# Set remote backup target
