![]() Using a tape library for offsite storage enables you to store your backups in a safe location (like a security deposit box or a third-party storage locker) that –unlike the cloud–you have physical access to. With a local disk, you can quickly back up your environment and have the backups available for fast restore. Disk and Tapeĭisk remains the most common storage media, and tape continues to make strides in speed and storage capacity. Hard drive reliability is closely related to temperature. The following are key considerations for implementing a 3-2-1 backup strategy, as well as for enterprise-level backup in general: Reliability: One obvious concern for backup is the reliability of the solution. Transferring those backups to the cloud as an offline process allows you to avoid touching the original source multiple times. Learn about best practices in the 3-2-1 backup strategy. Leveraging an on-site NAS ensures a large dedicated storage pool and high bandwidth for your backups. The last step in the 3-2-1 (1) strategy is to make sure you have a backup offline so that it cannot be accessed by, for example, hackers. ![]() NAS devices are an affordable on-site storage location for backups. A remote backup on a cloud storage location insulates your business data from disaster, malware, and other problems that arise. A 3-2-1 backup strategy is still viable, but more extensive, comprehensive strategies exist that make up for the vulnerabilities introduced by connectivity. A available backup on a local disk translates into very fast recovery time, as the local network allows for much higher bandwidth. Disk and CloudĬombining local disks and cloud storage locations is a common pattern for a small business backup strategy. Let's walk through a couple 3-2-1 workflows. You can choose to utilize a second cloud storage location (a 3-2-2 strategy) or NAS, tape, and cloud (3-3-2) for further redundancy. Although the process doesn't guarantee that all data will never be compromised in some manner, the strategy eliminates some of the risks involved in backup procedures. Going beyond the 3-2-1 backup rule gives you extra data insurance. The 3-2-1 backup strategy is recognized as a best practice for information security and data protection professionals. Using a transfer script to copy backups to a second location enables you to perform the operation offline, without the original source needing to be used. For every scenario, the best approach is a backup script with a local destination and a backup transfer script to the offsite destination. Retrospect Backup makes it easy to implement a 3-2-1 backup rule.
