Functions

Menu

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

adcOrigem

Prompts the user to add a source directory for backup.

rmvOrigem

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

setDestino

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

freqBackup

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

getInput

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

startBackup

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

Example Cron Schedule

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.

Notes

• 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.
