Under this scenario, a fraction of the data to be recovered is sent across the WAN link. This could speed up a remote restore significantly. However, there are some downsides to this type of scenario: • If step 1 is not followed correctly, any changes not fully replicated are lost. • During steps 2 and 3, any data that is written to the original DR Series system source container may be lost. • During step 4, if the data is not fully replicated back before the switch is made, it may be lost. Alternatively, you could still support this type of effort by completing the following: 1. Create a new container on the target DR Series system. 2. Set up replication from this container back to the source DR Series system container. 3. Set up a new disk storage unit in the DMA and make sure that the DMA is aware of any new images. 4. Import the old images back into the DMA from the target DR Series system (the original source location). 5. Use a new disk storage unit in the DMA, and then restore the data back to the original client. Reverse Replication: Alternate Method To support an alternate method of reverse replication, complete the following: 1. Create a new container on the target DR Series system. 2. Set up replication from this container back to the source DR Series system container. 3. Set up a new disk storage unit in the DMA and make sure that the DMA is aware of any new images. 4. Import the old images back into the DMA from the target DR Series system (the original source location). 5. Use a new disk storage unit in the DMA, and then restore the data back to the original client. Supported File System and Tape Access Protocols The DR Series system supports the following file system and tape access protocols. The Rapid Data Access (RDA) protocols below provide a logical disk interface that can be used with network storage devices to store data and support data storage operation. • Network File System (NFS) • Common Internet File System (CIFS) • DR Rapid - Rapid NFS - Rapid CIFS - RDA with OpenStorage Technology (OST) - RDA with NetVault Backup - RDA with vRanger • Virtual Tape Library (VTL) - Network Data Management Protocol (NDMP) - Internet Small Computer System Interface (iSCSI) NFS The Network File System (NFS) is a file system protocol that is designated to be a file server standard, and its protocol uses the Remote Procedure Call (RPC) method of communication between computers. Clients can access files via the network similar to the way that local storage is accessed. 18

Import the old images back into the DMA from the target DR Series system (the original source location).

Use a new disk storage unit in the DMA, and then restore the data back to the original client.
