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. NFS is a client-server application in which a client can view, store, and update files on a remote system just like they are working on a local system. System or Network Administrators can mount all or a portion of a file system, and the file system (or portion) that is mounted can be accessed using the privileges assigned to each file. NOTE: If you want to do a mount on AIX, you must set the nfs_use_reserved_ports and portcheck parameters first. The parameters cannot be set to 0. For example: root@aixhost1 / # nfso -po portcheck=1 root@aixhost1 / # nfso -po nfs_use_reserved_ports=1 18

Set up replication from this container back to the source DR Series system container.

Set up a new disk storage unit in the DMA and make sure that the DMA is aware of any new images.

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.

Reverse Replication: Alternate Method

To support an alternate method of reverse replication, complete the following:

Create a new container on the target DR Series system.

Set up replication from this container back to the source DR Series system container.

Set up a new disk storage unit in the DMA and make sure that the DMA is aware of any new images.

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.

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.

NFS is a client-server application in which a client can view, store, and update files on a remote system just like they are

working on a local system. System or Network Administrators can mount all or a portion of a file system, and the file

system (or portion) that is mounted can be accessed using the privileges assigned to each file.

NOTE:

If you want to do a mount on AIX, you must set the nfs_use_reserved_ports and portcheck parameters first.

The parameters cannot be set to 0. For example:

root@aixhost1 / # nfso -po portcheck=1

root@aixhost1 / # nfso -po nfs_use_reserved_ports=1
