# Description: I have all of my Docker data stored in a root directory called dockerData. 
# This script compresses that folder into an archive, names it, and uploads it to my NAS as a local backup.

# Variables:

# Get the current date in the format YYYY-MM-DD
current_date=$(date +"%Y-%m-%d")

# Define the source and exclusion locations, as well as archive name
source_folder="/path/to/dockerData/"
exclusion_folder="???" # ex: I exclude Plex because there's like 20gb of metadata that I don't really care about backing up...
output_archive="$current_date-dockerData-bkup.7z"

# Network share variables
smb_user="USERNAME"
smb_password="PASSWORD"
smb_ip="IP_ADDR"
smb_share="SHARE_NAME"
archive_to_upload="./$current_date-dockerData-bkup.7z"

# Move to source folder
cd "$source_folder" || exit

# Create a temporary directory to stage files
temp_dir="/home/prime/temp"
mkdir -p "${temp_dir}"

# Copy all files and folders (except the exclusion folder) to temporary directory
rsync -av --exclude="$exclusion_folder" . "$temp_dir"

# Archive contents of temporary directory
# note - requires: apt install p7zip-full
7z a "$output_archive" "$temp_dir"

# Remove temporary directory
rm -r "$temp_dir"

echo "Archive created: $output_archive"

echo "Proceeding with SMB connection & upload..."

# Connect to the SMB share and upload the file
# note - requires: apt install smbclient
smbclient "//$smb_ip/$smb_share" -U "$smb_user%$smb_password" -c "put $archive_to_upload"

echo "Standby..."

sleep 5

# Perform check if the upload was successful
if [ $? -eq 0 ]; then
    echo "File uploaded successfully."

    # Delete the original file
    rm "$archive_to_upload"
