Data Replication in Distribution Servers

 

Data Replication

To manage computers belonging to various branch offices of your enterprise (Computers in WAN), you will have to install unique Distribution Servers while creating Remote offices. Know more here.

Lets say you have five different branch (remote) offices with Distribution Servers and you are creating a configuration to manage a patch or to deploy a software to all the computers of your enterprise. Once the configuration is created, the associated software or the patch binaries will get automatically replicated/duplicated to the Distribution Server.

  • What happens if all your Distribution Servers happen to contact your main server at the same instance?
  • The Replication happens via WAN (Wide Area Network). What if your bandwidth utilization is not optimized and the transfer occurs during the peak productive hours of your enterprise?

You may face Server overload or downtime. To overcome this pain in deploying a patch or software across branch offices, Desktop Central lets you create "Replication Policy" and associate it with various remote offices. With Replication policy, you can customize

  1. Replication Interval, the time interval each Distribution Server takes to contact the Desktop Central's main server.
  2. Data transfer rate, the bandwidth used in transferring data to the Distribution Server.
  3. With the scheduler, you can plan and organize the time of Patch or Software data replication from the Server to Distribution Server.
    Note: You can schedule the replication of the patch or software binaries only if you are using Desktop Central build number 10.0.173 or above.

Lets say you have created three different Replication policies and associated it with your branch offices 1,2 and 3 respectively. Now if you create a configuration to manage a 5 mb patch and deploy it across your network, the transfer of binaries will happen only in-accordance with the time and the data transmission rate that is specified in the associated Replication Policy.

  • Branch Office 1: The Replication policy associated with branch office-1 will start replicating the binaries from the Desktop Central's main server only during weekends in between 00.00 and 11:59 hours.
  • Branch Office 2: In branch office-2, the replication occurs on all days during non-working hours. i.e, from 21:00 to 6:00.
  • Branch Office 3: In branch office-3, the replication window is open 24*7 and the data replication will take place immediately, when the Distribution Server contacts the main server.

Once the data replication is complete, the configuration will get deployed in the subsequent deployment window to all the WAN agents. Know more on deployment window and Deployment Policy here.
