Backup Script

This script creates incremental backups using rsync and manages retention of old backups.

Configuration

• Set the SOURCE_DIRS variable to specify the directories you want to back up.

• To back up multiple directories, you can simply add them to the SOURCE_DIRS array in your script.

  SOURCE_DIRS=(
      "/path/to/files-to-be-backup"
      "/path/to/another-directory"
      "/path/to/yet-another-directory"
  )

• Set the BACKUP_ROOT variable to specify the directory where backups will be stored.

• Set the RETENTION_DAYS variable to specify how many days of backups you want to keep. Backups older than this period will be automatically deleted the next time the script runs.

Warning

• Be careful when setting the BACKUP_ROOT variable. If misconfigured, the script could delete important files.
• Review the script and customize it for your needs before using it.

Usage

1. Make the script executable:

   chmod +x backup.sh

2. Run the script:

   ./backup.sh
