Data Center Replication
When working with multiple data centers it is often important to make sure that if one data center goes down, another data center is fully capable of picking its load and data. Data center replication is meant to solve exactly this problem. When data center replication is turned on, GlobeNet in-memory database will automatically make sure that each data center is consistently backing up its data to other data centers (there can be one or more). GlobeNet supports both active-active and active-passive modes for replication.
Local & Off-Site Backup and Replication
Offsite backups of Virtual Machines (VMs) and their data form a key part of a complete BC/DR solution as they are the last line of defense in protecting the business in the event of a disaster. By having a 3rd copy of the data kept offsite, no matter what happens with the primary site, local server backups, data replication or even recovery site the business always has the ability to recover.
The most common method of maintaining offsite backups is to use legacy tape or disk based backup solutions with tapes taken offsite on a daily or weekly basis. The tapes are then stored long term serving the dual purpose providing of a 3rd copy of the data and long term data retention for archiving as maintaining long term backups is often required to meet business and regulatory requirements.
Disaster recovery as a service (DRaaS) is the replication and hosting of physical or virtual servers by a third party to provide fail-over in the event of a man-made or natural catastrophe.
Typically, DRaaS requirements and expectations are documented in a service-level agreement (SLA) and the third-party vendor provides fail-over to a cloud computing environment, either through a contract or on a pay-per-use basis. In the event of an actual disaster, an off-site vendor is less likely than the enterprise itself to suffer the direct and immediate effects, which allows the provider to implement the disaster recovery plan even in the event of the worst-case scenario: a total or near-total shutdown of the affected enterprise.
