Without a reliable backup system, companies risk not only financial losses but also damage to their reputation.

Types and strategies of backups

There are various backup methods, including Full backupswhere all data is backed up completely, as well as incremental and differential backupswhich only record changes since the last backup. Backups can be made to external hard disks, network storage (NAS) or in the cloud be stored.
