Server Mirroring is a process of channeling data from the Master server to the Slave server so that an identical copy of data exists on the Slave server. In other words server mirroring can also be described as utilizing a backup server that duplicates all the data of the master server. After the implementation of mirroring, if for any reason, the master server fails, the slave server can immediately take its place without any downtime.

The usage of server mirroring technology can solve many different issues such as:

Automated Data Back-ups: Tracking file changes independently and replicating those changes using Rsync, thereby
maintaining a real-time copy of data than copying an entire file that has changed.
Disaster Recovery: No downtime with real-time disk-to-disk synchronization.
Enable efficient use of server resources and increase overall redundancy of each server.

Data Replication

We at eUKhost have implemented Mirroring Solution using FAM and RSYNC modules. For Server Mirroring we set-up 2 similar configuration servers in 2 different racks out of which one server is master server and other is slave. Any file update or change on the master server flags itself and FAM gets notified about the Flag. FAM module then sends a request to Rsync to copy the file update on the Slave server and the file is immediately transmitted on to the Slave server. This process is completed in a very short period of time and doesn't use up any server resources even if the files which are changed are of larger size.

Failover/Failure monitoring

Failover is a process in which the slave server stands in for master server in case the master server goes down. With the help of Failover, user and application requests that are directed to the failed master server are routed to the slave server. This is done with the help of a monitoring script running on the Slave server which binds the Secondary IP of master server ( IP allocated to websites ) and all other Dedicated IPs on the slave server. Websites/applications on master server then start resolving from the Slave server in fraction of a second and function in the same manner as they used to on the master server.

Restoration

Restoration provides an easy method for copying replicated data from the slave server back to the master server. Restoration process only requires selection of the source, target, and the appropriate replication set. There is no need to select files or to remember where the data came from on the source since that information is maintained by Rsync. Restoration can be used if the data on the master server is lost due to a disk crash or when the most up-to-date data exists on the slave server due to failover. At the time of a master server failure, the slave server will contain the same data as the master server. Because of the continued updates on the slave server, when the master server is back online, the two servers will no longer contain the same data. Restoration is the process of copying the incremental data from the slave server back to the master server.

We offer Enterprise Server Load Balancing solutions, Server Mirroring and Failover Redundancy to ensure 100% server & uptime guarantee along with 100% network guarantee! If you are looking for any of the above solutions, all you need to do is sign-up for two or more servers and we will make them into a Mirroring/Failover/Load-balancing solution as per your requirement.
