Continuous Data Protection in Perfect Sync with Microsoft
Thanks to Double-Take Software, continuous recovery for Microsoft data is reliable, hassle-free and delivers the up-to-the-second protection—regardless of where that data resides. It’s the Microsoft-approved solution for continuous data protection, featuring:
- Asynchronous host-based replication for near-real-time data replication and CDP
- Superior data replication that doesn’t impact the production environment
- Flexible integration with any hardware, service provider or storage architecture
- Minimal installation and training
Double-Take Backup is ideal for Microsoft data protection and preferred among companies looking for affordable, manageable data backup and recovery. Our real-time replication protects your Microsoft data better than periodic tape backup--and without the cost and complexity of other hardware-based systems.
Our patented software-based replication and failover technology is the secret behind our success. Double-Take Backup provides asynchronous replication that continuously captures byte-level data changes as they occur and replicates those changes to one or more target servers at any location (locally or at recovery site miles away). In the event of disaster or downtime, Double-Take Backup’s continuous data protection feature helps you recover in minutes—if not seconds.
And, unlike synchronous replication which requires proprietary hardware and can be costly, Double-Take Backup lets you use any hardware, storage service provider or storage architecture that you choose. Performing migrations to new hardware, implementation of a SAN or NAS, or any other project that requires moving data from one storage device to another is simple and efficient. With Double-Take Backup there are no distance limitations. Best of all, there is no installation or training required every time new hardware is added, making Double-Take Backup the easy choice for continuous data protection that’s easy to manage.
Benefits of Double-Take Backup Asynchronous Replication
- Captures the data for processing but does not keep it from updating the local disk
- Copies only the byte-level changes to files, not entire blocks (physical or logical) or entire files, reducing overhead on the servers and the network
- Ensures that all transactions are captured and written in order on the target for maintaining exact replicas
- Captures changes as they are made, for near real-time replication and continuous data protection
- Integrates seamlessly with any hardware, SAN or storage architecture
Disadvantages of Traditional Synchronous Replication
- Local disk is only updated after replicated data has been written/committed to the target disk and the corresponding acknowledgement has been sent back to the production server
- Performance on the production application is decreased while waiting for confirmation that the replication has occurred
- Requires proprietary hardware that adds cost and complexity
