// Your answer to this question determines the backup intervals. If you don't want to lose any data at all, your data needs to be backed up constantly. You can extend the backup intervals a little if losing a few hours of data would not be so tragic.
The best storage location for the data backups (external hard drive, network drive or the cloud etc.) and the frequency of storage can also differ significantly from company to company. Nevertheless, data backups in the cloud are likely to be the most flexible and convenient option, as the cloud provider is responsible for providing the latest hard- and software and for compliance with relevant standards.
This type only copies data that has changed or been added since the last full backup. It requires considerably less storage space than a full backup. Shorter backup intervals are therefore possible. Individual restore points can be deleted without affecting others.
Incremental backups only copy the data that has changed or been added since the last incremental or full backup. All incremental backups and a full backup can be used to restore systems and data. Very short backup intervals are sensible and possible, as the method does not require much storage space.
The various backup methods are combined: Incremental or differential backups can be performed after a full backup.
