There are a number of data backup options. It's important to choose the right option for you and your organisation.
Cloud backup
Cloud backups can be run on software (such as Veeam) which allows organisations to back up their data to hardware in a remote location i.e The Cloud. This is a great option for offsite backup as it is encrypted, requires authentication and is a hands-off method for the business. Restoration points can be captured more frequently due to availability of large amounts of storage space.
External Hard Drives
Another form of offsite backup includes rotating hard drives, this is where data is encrypted and backed up to an external hard drive. The business needs to rotate these drives, the idea being that one or many hard drive/s are always offsite as a form of data recovery in the case of an onsite disaster.
Backup Servers & Network Attached Storage
An onsite solution involves taking backups of data and storing them on a secondary backup server or network attached storage (NAS). This is a fast recovery method and is a highly secure option and should be paired with an offsite solution to cover your business in the case of an onsite disaster.
