![]() Like the data migration solutions discussed here, some businesses require that data is sent to an alternate location for local access. Data Distributionĭata protection and availability are not the only uses of a replication solution. It is not necessary to stop all user access in order to move the data. A huge advantage of using Double-Take for migrations is that the data is continuously updated on the new server/storage, allowing users to be cut over at any time. In all cases, the fundamental requirement is that the data is moved from one Windows platform (with local storage) to another Windows platform (with more manageable storage), like that of a Windows-Powered NAS (or Storage Server). Using the same techniques outlined above for data protection, one can migrate from local storage to a NAS, a server utilizing a SAN, or even a NAS-gateway to the SAN. NAS to SAN storage migrationĪs more environments move from direct attached storage to NAS or SAN, the question of how the actual migration will occur becomes more frequent. This increases the backup window to a full 24 hours and ensures there are not missed or inconsistent files because they are actively open and updated. In addition, the backup occurs at local disk/tape speeds, instead of a media server scheduling the backup up multiple application servers. Without expensive and application-specific backup agents, the second copy of the data is archived to tape using existing tape technology attached to the redundant server. However, the redundant copies of files on Double-Take target servers can be backed up at any time, even when the original copy of data is in use. This results in an ever-shrinking backup window. Today's corporations are increasing their business day, as geographic and national boundaries no longer limit effective commerce. Backup processes can also run 24 hours a day without impact on the production servers. This provides disaster recovery for the branches, and allows backups to be managed at the centralized facility by trained IT personnel using more advanced tape technologies. By efficiently replicating the byte-level changes within the data at the branch offices using Double-Take, one can bring the branch's data back to a centralized data center. The result is higher labour costs and lower restore reliability. ![]() Many times this requires non-IT personnel to be responsible for tape rotations and cleanings. Branch office server to Centralized Data CentreĮnterprise branch offices tend to be isolated because of WAN performance, hardware and management costs. The result is rapid availability of the data - and the small office continues doing business. Double-Take provides a simple and cost-effective way to "fail over" to a second machine, either in the same office or perhaps even at an employee's home. When the primary server fails, the office productivity can halt. ![]() Large enterprises may have multiple data centers and a myriad of server technologies, but the typical small office relies heavily on few servers, often with limited IT resources or personnel. The Double-Take Solutionĭouble-Take provides powerful solutions for a number of data protection, data availability, data migration, and data distribution challenges. There really is no limit to what you can replicate using Double-Take.Īs long as the data is flowing between Microsoft Servers you could replicate 1 server locally, 20 servers located in branches around New Zealand or 100 servers replicating between here and the rest of the world. ![]() Double-Take can handle multiple data protection, availability, migration, and distribution needs.
