Backup solutions are methods and tools used to create copies of data to protect against loss or damage. These solutions can include physical storage devices like external hard drives or cloud-based services that store data online. Regular backups ensure that important files, such as documents and photos, can be recovered in case of accidental deletion, hardware failure, or cyberattacks. There are various types of backup solutions, including full, incremental, and differential backups. Full backups copy all data at once, while incremental backups only save changes made since the last backup. Differential backups save changes since the last full backup. Choosing the right solution depends on individual needs and data importance.
