# This script creates a tar.gz backup of the /opt/AdGuardHome directory, cron jobs, and system logs.
# The backup is stored in the './backups/' directory.
#
# To automate backups, you can add this script to your crontab.
# For example, to run this backup on the 1st of every month, you would add the following line to your crontab:
# 0 0 1 * * /path/to/this/script.sh
# (Remember to replace '/path/to/this/script.sh' with the actual path to this script)
# You can edit your crontab with the command: crontab -e

# Get the current date in a suitable format for the filename
current_date=$(date +"%Y-%m-%d")

# Create the backup filename
backup_filename="adguardhome_backup_${current_date}.tar.gz"

# Default backup location
backup_location="./backups/"

# Create the 'adguardhome' directory if it doesn't exist
mkdir -p "$backup_location/adguardhome"

# Create the tar.gz archive
tar -czvf "$backup_location/adguardhome/$backup_filename" /opt/AdGuardHome /var/spool/cron/crontabs/* /var/log

# Print a success message
echo "Backup created successfully in $backup_location/adguardhome/$backup_filename"

# Delete backups older than 90 days
find "$backup_location/adguardhome" -mtime +90 -type f -delete
