Here are the 3 types of data backup options with a summary comparison table and infographic to help you choose which would suit your business.
Traditional Local Backup
In its simplest form, local backups are copies of information from a source such as a computer system hard drive to a destination such as a USB hard disk drive. In addition to high hardware and administration costs, neither tape nor disk will provide disaster recovery unless they are stored off-site.
The most common form of cloud data storage consists of a collection of hard disk drives housed in a building known as a datacenter and maintained by a company devoted to ensuring the security and reliability of the datacenter. Inside the datacenter may be an elaborate system of computer servers, networking equipment, and hard disk drive storage.
Cloud backup is the process of securely copying data from a primary source, such as a computer system hard drive to the destination data storage. Data are typically encrypted during the copy process and may also be stored in an encrypted manner in the cloud data storage.
The key drawbacks with pure cloud are that it is very much restricted by available bandwidth. So, it’s not an approach suited to organisations with large and complex backup requirements that would hog Internet connections. Likewise, if you’re likely to need restores of large files that would take a long time to download, pure cloud will not be for you.
Hybrid backup is the combination of both cloud backup and local backup, where local backup is typically a USB drive, tape or NAS device. The ideal hybrid backup solution integrates these forms of backup in an automatic, user-friendly utility running transparently in the background. While local backups are typically sufficient for protecting the data and other information on a computer system, the cloud backup adds a level of assurance that offsite backup data is safe from disaster.
