What is data backup? What is data protection? These questions may sound as simple as they look, but the answers can be much more complicated. Data backups and protection are important parts of any business continuity plan. It is crucial to know how to protect your digital assets using different tools and techniques, but it can be difficult to decide which method is the best for your business.
Data backup is a process of copying digital assets in order to protect them from loss or damage. It also provides fast recovery if an unexpected event occurs that affects computer files. There are many different ways to create backups, but most businesses use one or more of these methods: at-rest (offline) and in-transit (online).
At-rest backups are stored in a secure location. There are many ways to store the backup, including with an optical disc or in cloud storage. If someone gains access to your at-rest data, you do not have much time to detect the problem because it happens while the files are being copied. In-transit backups are sent over a network or device to another server. It can be helpful because you do not need to worry about storing the backup, but the risk of data loss increases if your internet connection is slow (increased latency) or goes down completely.
Both methods have their benefits and weaknesses, which means that there is no universal backup solution. You need to decide which one is right for your company and research how to back up your digital assets. It is also highly recommended that you use more than one method, because this increases the speed of data restoration and reduces the risk of losing all your files in case something happens with a single backup copy.
Data protection is an umbrella term that refers to all the tools and techniques used to keep your data safe. Most businesses use multiple security measures, such as network monitoring and firewalls, but data protection also includes data backup and recovery solutions. The three main goals of protecting your files are:
prevent loss or damage
detect and recover from the loss or damage
minimize downtime, if recovery is required
Data protection should not be confused with disaster recovery (DR). The two terms are often used interchangeably, but they mean different things. While data backup solutions provide security against accidental file loss or hardware failure, DR is a set of policies and procedures that allow a company to operate during a disaster.
