Final project for Systems Administration.

• Add multiple source directories for backup.
• Specify a single destination directory.
• Set backup frequency using cron scheduling.
• Start and schedule backups.
• Color-coded interface for better readability.

Run the script in a bash terminal to start the backup manager.

./backup_script.sh

1. Add Source Directory: Add one or more directories to the list of sources to be backed up.
2. List and Remove Source Directories: Display the current list of source directories and remove any if needed.
3. Set Backup Destination: Specify the destination directory where backups will be stored.
4. Set Backup Frequency: Define the schedule for the backup using cron syntax.
5. Start and Schedule Backup: Initiate the backup process and set up the cron job.
6. Exit: Exit the backup script.

• Blue: General information and prompts.
• Green: Success messages.
• Red: Error messages or warnings.
• White: Default text color.

Displays the main menu and handles user input for various options.

Prompts the user to add a source directory for backup.

Lists current source directories and allows the user to remove any.

Prompts the user to set or change the backup destination directory.

Prompts the user to set the schedule for backups and validates the input.

Checks if a cron schedule is already set, prompts the user to set a new schedule if needed.

Validates the source and destination directories, creates the backup script, schedules it using cron, and executes the backup.

To set the backup schedule, provide the following inputs when prompted:

• Minute: 0-59 or *
• Hour: 0-23 or *
• Day of Month: 1-31 or *
• Month: 1-12 or *
• Day of Week: 0-6 or *

The script will generate a cron schedule string and inform you of the set schedule.

• Ensure the script has execute permissions.
• The script will create the backup directory if it does not exist, upon user confirmation.
• Only one backup destination can be set at a time.
• The script will remove any previous backup cron jobs before scheduling a new one.
