Scheduling Synchronization Jobs

Published : September 27, 2005

You can choose between two modes of synchronization: Only before each shadow copy is created or Nearly-continuous (hourly).

Nearly-continuous (hourly) synchronization distributes the load on the network throughout the day. When synchronization occurs Only before each shadow copy is created, the network traffic is potentially greater, but data is not sent throughout the day.

If an organization has limited network bandwidth between the file server and the DPM server and this limited bandwidth is also expected to be shared by backup operations and normal corporate usage, consider using synchronization only before shadow copy and schedule it during off-peak hours.

Although the impact on network traffic and performance is important, you must also consider how the choice of synchronization mode affects your ability to recover data. If you only synchronize once a day, the maximum loss window is 24 hours. However, if you choose to synchronize every hour, your maximum loss window is 1 hour.
