Cloud Replication is a technology that safeguards data in the face of a catastrophic event or disaster by replicating or reproducing the servers and storage to an entirely different geographical area, allowing the systems to fail over and replicate at the new location within minutes. This technology diminishes or eliminates the need for an active-active configuration and costs significantly less. Whatever your company’s primary location for its production systems, should something happen, your data would be replicated elsewhere to ensure business continuity.
Cloud Backup can provide two general solutions – Backup/recovery of a company’s local systems to a cloud-based system, or backup/recovery of a company’s cloud-based systems to a cloud-based backup. Backup/recovery systems use point-in-time data so there is a limit on how many backups will be stored and how long they’ll be stored for (e.g. 1 backup once a week for 4 backups a month, with a limit of 50 backups saved). This dictates the amount of backed-up data that can be restored. Most backup/recovery systems also utilize compression technologies that significantly decrease the amount of data stored, which might allow for more backups.
An example of data backup/recovery of a local system to a cloud-based system would be a business with several locations, where each location has local production servers and on-site storage, making them susceptible to a disaster at any location. However, these locations could use cloud backup to safeguard their servers and storage from any type of disaster – a fire, a flood, a tornado, or an earthquake. Each location would have their own data/records retention policy (an organization’s standard procedure/process for retaining data and information for compliance or business reasons) and would backup/restore independently from the other locations. In the event of a catastrophe, that location (or any location affected) could restore their data from the cloud.
