Different Types of Data Recovery Systems
There are several different types of data recovery systems that organizations and businesses use to recover data. Before you choose the type of data recovery system that is appropriate for your organization, you must assess all of the critical levels of your data and systems to determine a policy and recovery system that will be well-suited to your organization.
Assuming you have done the data assessments, there are several different types of recovery that you can use in the event of data loss.
Bare Metal Recovery
Bare metal recovery involves backing up the entire system including the operating system, software applications, and data. In the event of data loss, bare metal recovery allows you to restore the entire operating system in a single procedure which reduces the recovery time by hours. This prevents you from having to reformat everything from scratch by reinstalling the operating system, software applications, and restoring the data and settings.
Online Disk Backup
With online disk backup you can backup your data more frequently which is ideal for data that is constantly changing on a daily basis. An online disk backup service also provides tiered recovery architecture which provides more flexibility and options with organizations that require frequent critical data backup and intermittent backup for data that is not as critical.
Online disk backup is a time saver as well as a money saver. It is important to note that you should do your homework when choosing an online disk backup service to ensure they are reliable and enforce security policies and regulations.
Continuous Data Protection
Continuous data protection (CDP) is also known as continuous backup and saves time in the recovery process because it contains a dual purpose method of backing up data. With continuous data protection, you can backup data on your local area network onsite while simultaneously backing up the data to an offsite location. If the organization suffers data loss onsite, the CDP can tap into the offsite data backup system.
In addition to a dual method of backing up data, a continuous data protection backup creates a log of complete storage snapshots as well as any modifications to the data that occur since the last backup. The installation of a continuous data protection system is fairly straightforward and if it contains disk storage, recovery time is almost immediate.
Continuous data protection is gaining momentum with a lot of organizations due to its ability to continuously monitor and record all modifications to data and then backing it up both onsite and offsite.
