![]() A snapshot is created so the backup storage always remains in a pristine state and all user write operations are redirected to that snapshot. In general, data recovery refers to the restoration of data to a server or external storage system from a backup.įor example, instant recovery (recovery in place) attempts to eliminate the recovery window by redirecting user workloads to the backup server. Having a backup is good, but what about recovering the data from your backup? Data recovery is the process of restoring data to storage space that has been lost, accidentally deleted, corrupted or made inaccessible. In addition to full data backups, organizations typically schedule a series of differential backups 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 any deleted 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. ![]()
