Virtualization is often the basis for BCDR but can be a stand-alone technology. It’s another use of a virtual server this time pulled from a backup. Virtualization Programsĭata virtualization is highly similar to a BCDR. File restoration may take only a few minutes, while bare metal restoration can take hours, depending on what is left in the system. Most restoration programs are capable of performing at all three levels of severity and work relatively quickly. This is used in the event of either a wide scale logical failure or a physical failure. ![]() This is the most intense kind of restoration, as it seeks to recover an entire system from a backup. A step up from file restoration, volume restoration is a program that seeks to save a number of files and folders lost to logical failure.īare Metal Restoration. This is the most straightforward kind of data recovery method, as it focuses on a single file that has been lost to a logical failure. Restoration is performed on three levels:įile Restoration. ![]() Then, if the data is found, it is pulled back and established as an indexed file that can be resaved to the system proper. These programs use sophisticated algorithms to dig through unindexed or alternatively indexed data in an operating system. Restoration is the most common kind of ransomware recovery. They basically eliminate the need to manually reboot after a failure, saving you time that you can potentially use to assess and address the damage. In the event of a data disaster, the system would be transferred over to the BCDR in a matter of minutes, which would boot up the latest version of the servers and programs to get your business up and running as fast as possible.īCDRs are an excellent failsafe to employ for automatic recovery. Business Continuity and Disaster Recoveryīusiness Continuity and Disaster Recovery, or BCDR, is a system that stores snapshots of the current servers and programs your business uses. They can also be quicker to access and implement in the event of a disaster than traditional, physical backups. With cloud storage, no physical device is needed your data is encrypted onto a secure server that can be accessed from any device with the proper credentials and permissions.Ĭloud backups are easy to update and maintain, as they can be set to run on a regular schedule to log your organization’s information. This method utilizes backup systems such as Rubrik, which offer protection of data in the cloud and across on-premises and remote environments. The modern replacement for physical backups is cloud storage. If the physical backup device is damaged in the initial data disaster, your data is still lost. This is potentially the oldest method, as tape backups have been around since essentially the beginning of digital data, but because of its antiquity, it also has a significant drawback. Physical backups are good in that there’s no guessing about where the information is or how to access it. These are physical devices that serve essentially as another computer in the event of a failure with the primary system. Physical backups consist of things like CDs, flash drives, and external hard drives. Here are some of the best and most common methods. ![]() ![]() There are many ways to handle a data backup and restore what you lost. The Best Data Backup and Recovery Methods In addition to full data backups, organizations typically schedule a series of differential or incremental data backup jobs that back up only the data that has changed since the last full backup took place. The process is governed by predefined policies that specify how frequently the data is backed up and how many replicas (duplicate copies) are required, as well as by service level agreements ( SLAs) that dictate how quickly data must be restored. So what data should be backed up and how frequently? A backup process is applied to critical databases or applications. Notably, backups are usually an organization's best option for recovering from a ransomware attack. Backups provide a way of restoring deleted files or recovering files that are accidentally overwritten. Simply put, data backups guard against data loss. Organizations back up their critical data, capturing and synchronizing a point-in-time snapshot that is then used to return data to its previous state. Backing up data is a crucial component of any disaster recovery (DR) plan. Data backup is the process of copying physical or virtual files or databases to a secondary location for preservation in case of equipment failure or other disaster scenario. ![]()
