To do so, these solutions use snapshot and virtualization technologies to create and store bootable virtual server images on a backup device or in the cloud. Backup and recovery in cloud computing is still evolving and will continue to develop as more businesses migrate workloads into the cloud.īusiness continuity/disaster recovery (BCDR):īCDR solutions are designed to enable fast restores that minimize business downtime. Data created in SaaS applications is just as vulnerable to accidental or malicious deletion and ransomware attacks as on-premises data. Many organizations believe that because SaaS data exists in the cloud, there is no longer a need for backup. SaaS backup refers to backing up data created in SaaS applications such as Microsoft 365 or Google G Suite. Cloud-to-cloud backup is the process of copying data from one cloud to another cloud. With direct-to-cloud, offsite file backups are copied directly to the cloud, bypassing the need for a local device. Direct-to-cloud backup, cloud-to-cloud backup, and SaaS backup During this time, business operations are seriously compromised, which of course results in damaging revenue loss. Using traditional backup methods, recovery can take hours or even days.
However, restoring a large amount of data (say, the contents of an entire server) from offsite tape or cloud is slow. Traditional disk backup solutions have the ability to offload data to tape or the cloud for disaster recovery and/or archiving. Other than backup and restore speed, disk backup also allows users to retrieve individual files without the need to first restore an entire data set. The primary benefits of tape are massive capacity, low cost, and offsite data backup.ĭisk backup emerged in the 1990s and grew in popularity through the early 2000s, because it offered much faster backup and recovery than tape systems. Tape is still commonly used today for large enterprise system backup, archiving, and even for long-term cloud storage. Tape backup has been around in some form or another since the 1960s. Types of data backup Traditional tape or disk backup These are important considerations when selecting a backup and recovery solution. Finally, critical data may live on workstations, local servers, and in the cloud. Additionally, restore needs also vary (e.g., restoring a single file vs. Restore and recovery times can vary widely depending on the backup format and data recovery methods you choose.
Products aimed at rapid recovery of data and operations are typically referred to as business continuity and disaster recovery, or BCDR, solutions. Recovery refers to the process of restoring data and operations (e.g., returning a server to normal working order following hardware failure). It also could mean copying data from the cloud to a local device, or from one cloud to another. This might mean copying data from backup media to an existing device or to a new device. Restore is the process of retrieving data from a backup. An offsite data backup is a key part of any business continuity/disaster recovery plan. Data backups can be created locally, offsite, or both. Backup is the process of creating a copy of data to protect against accidental or malicious deletion, corruption, hardware failure, ransomware attacks, and other types of data loss.
