Minimal Down‐time should not depend on hardware!
What are your requirements?
Linux support
Traditional Backup is no longer good enough
Double-Take replicates data as soon as changes are written to disk in transactional fashion over ip to one or more servers taking care of the recovery point. When it comes to making the availability of the application, it is a matter of pointing the users there. The data already exists, so no need for downtime to restore!
Double-Take is about keeping availability simple. Independent of application or hardware. There’s a production server we can call source that replicates changes at the byte level to a redundant server we call target. In event of individual server failure or site failure, we failover and our users remain productive on our target. When we’re ready to failback, we kick‐of the restore to either original or new hardware, while our users remain on‐line and working on our DR server. Once a restore is completed, we maintain the changes users create with replication, so you remain in control for when you want to switch them over to original production infrastructure. Failover and Failback will work over Lan or Wan – what are your requirements ?
Capture beneath the Application ensures data integrity and application independence. Capture above the hardware layer, ensures no dependency on current or future hardware infrastructure to facilitate Application Availability, Disaster Recovery or real‐time migration or backup. True, byte-level transactional replication.
Easy to use wizard driven configuration. What are your requirements ?
