Executive summary

This paper provides information about how to set up seeding from a Dell DR Series system to an external device through the Dell DR Series command line interface (CLI). This paper is a quick reference guide and does not include all DR Series system deployment best practices.

For additional information, see the DR Series system documentation and other data management application best practices whitepapers for your specific DR Series system at:

1 Understanding the seeding process

Seeding is a process that copies de-duplicated data from a DR Series system to an external device (typically USB), which is exported as a CIFS share. The seeding process comprises the following steps:

1. The device attached to a client machine is mounted using the CIFS protocol on the DR Series system;

and, seeding is initiated, which copies the data (export) to the device.

2. Once the data is copied entirely, the devices are later shipped to the location of the target DR Series

system.

3. The device is attached to another client at the remote site and mounted using the CIFS protocol on

the target DR Series system.

4. The data is imported to the target DR Series system.

5. Once all of the data is imported, replication re-sync is initiated between the source and target DR

containers. Since the data is already present on the target, the re-sync completes quickly after transferring the namespace with any other changes in data. Replication setup is ready between the source and target.

The following diagram shows this process.
