Quest’s DR Series Appliance is a remarkable device. It has amazing deduplication and compression, source-side and inline deduplication capabilities, is certified to work with most major backup software vendors, plus many more incredible features. It also has WAN-optimized replication that lets you send deduplicated and compressed data from one DR container to another. It even gives you the ability to throttle your replication bandwidth and schedule when data is sent over the WAN. This optimized replication will allow you to keep redundant copies of data in separate DR’s while putting minimal stress on your network. However, even with deduplication and compression, replicating an initial set of backup data from one unit to another can still take a while and consume your available bandwidth during that period. So what should you do if you can’t afford to lose that bandwidth but you need to replicate? Well, there are two possible solutions.
The first solution is to bring your remote DR onsite so that the two DR units can replicate over a much larger network. This is a good and reliable solution, especially if you have not already sent the remote DR to its final destination. It allows the data transfer to put less stress on your network, speeds up the rate of data transfer, and allows you to verify that both units are set up correctly when they are both in close physical proximity to each other. However, if this is not a practical course of action, for whatever reason, then there is still another solution.
The second solution involves seeding the data from your local DR to a removable USB hard drive (mounted as a CIFS share on the DR) then physically moving that hard drive to the location of the second DR and ingesting it into the remote device. Please read the entire process before attempting. The process is very simple and is described below:
There are some important things to know about the export seeding process:
Once you have seeded the data to an external USB drive and physical moved the drive to the location of the remote DR, you can import the data using the process described below:

The final step in the process is to re-sync replication between the source and target DR devices. To do that, complete the following steps:
