A full backup is performed first and then subsequent backups are then run to include any changes to folders and files. This type of data backup involves backing up business data that was created or changed since the previous full backup. Differential Backupĭifferential backups have components of both a full backup and an incremental backup. Restores are a little more complicated than with other backup types as all backup sets, including the first full backup and succeeding incremental backups, are needed for restoration. Of course, there are some disadvantages of using an incremental backup. Incremental backups need the least amount of storage space, but they must be managed separately during the recovery process. Incremental backups are known to be lightning-fast as they are only required to store changes made since the last backup. All succeeding backups are designed to only store changes that may have been made to the previous full backup. With an incremental backup, only the first backup is a full backup of business data. However, a full backup is generally the most reliable copy. Businesses that run a full backup are at risk of overloading their storage space, impacting backup speed. There are many benefits to choosing a full backup, including a relatively short timeframe for the restoration of important data.Īlthough a full backup is the most comprehensive approach to data backup, it does come with certain downsides. Full BackupĪ full backup is the most complete type of data backup where all of the selected data is cloned and stored, such as all files, folders, hard drives and SaaS applications. The four main types of data backup include a full backup, incremental backup, differential backup and mirror backup. There are several different types of data backup systems that organizations rely on to protect their company and avoid data loss events. Having a data backup system in place helps reduce downtime and allows businesses to recover their files quickly and effectively with the least impact on finances and productivity. Data backups are an essential component of disaster recovery that helps restore valuable computer data following a catastrophe.
