![]() A well-thought-out plan that is rigorously and regularly tested will allow an organization to resume operations quickly in the event of a disaster. Having data backup and disaster recovery systems in place is an important first step, but documenting what to do in the event of a crisis is vital. Without a data backup, there is virtually nothing to recover. The reason for this is simple data backup can exist without disaster recovery, but not the other way around. While data backup and disaster recovery are different, most organizations utilize them together. Data Backup and a Disaster Recovery Planīackup and disaster recovery (BDR) combines data backup and disaster recovery to ensure an organization’s resilience and operations continuity. A common recommendation is to store the backup data in the cloud at two geographically separated locations.Ī 3-2-1 data backup strategy provides a structure and process for ensuring data resilience under almost any circumstance. A commonly used tactic is to have one backup stored on a network-attached device or a file server and another stored on removable media or another server.Īt least one copy of the two backups should be stored at a separate location from the production data and the other backup. The way it works is this:Īlways have at least three distinct copies of the data-one is the production set, and the other two are backups.Īt least two copies of the production data should be kept on secure storage devices that are physically independent of each other. The 3-2-1 data backup strategy is brilliant in its simplicity. Designed to take into account a number of worst-case scenarios, the data backup strategy ensures that at least one copy of data will be available to use for recovery and operations restoration. The list of information in a data backup varies, but a few common examples are:Ī 3-2-1 data backup strategy provides a structure and process for ensuring data resilience under almost any circumstance. What Data Should Be Included in a Backup?Īny data that cannot be easily recreated or replaced should be included in data backup as a rule of thumb. Perform a checksum to verify that the original and backup files are identical.Ensure that the file dates and sizes are identical to the original copies.Confirm that there are no errors in opening files.Verify backups to ensure validity by performing spot checks to:.Locate the backup data in several locations, one of which is offsite (e.g., the 3-2-1 data backup strategy, which is explained in further detail below). ![]()
