Copy to Tape TOI Agenda 1 Overview 2 Technical Feature Implementation 3 Q&A 2

General Overview 3

General Overview • Open. Storage copy to tape lets you copy Net. Backup backup images directly from Open. Storage devices to the tape drives that are directly attached to the storage server or attached to an NDMP host. • This feature allows for the customer to perform direct Copy to Tape operations via SLP (storage lifecycle policies). The Media Server is not a data mover for this type of operation and that results in network bandwidth savings – as the data movement only has to make one hop. • This is a new feature to Net. Backup. 4

Technical Feature Implementation 5

Technical Feature Implementation • Process/data flow – Data flows from the Open. Storage Device, through the NDMP Server to the Tape Robot 7

Requirements The following are the requirements to use Open. Storage copy to tape: The Open. Storage disk appliance must support the Open. Storage copy to tape specification published by the Symantec Open. Storage Partner Program. The copy to tape capability uses a subset of the NDMP File Service Extension (FSE)commands. 8

Requirements In this document, disk appliance NDMP host refers to the host that provides the Open. Storage copy to tape support. The host may be the disk appliance storage server, an alternative name (that is, interface) for the storage server, or a separate host that interacts with the disk appliance. Regardless, the host must support the Open. Storage copy to tape specification. The host to which the destination tape drives are attached must be an NDMP tape server that Net. Backup supports. For supported systems, see the Net. Backup for NDMP Administrator’s Guide. Ideally, all of these functions reside on a single host. 9

Requirements The read side media server must run Net. Backup 6. 5. 4 or later. Net. Backup selects the read side media server from the Net. Backup media servers that have credentials for the disk appliance NDMP host. To allow all of the Open. Storage data movers (that is, Net. Backup media servers) to function as read side servers, upgrade all of them to Net. Backup 6. 5. 4. 10

Requirements One of the read side media server’s tasks is to ensure that the disk appliance NDMP host supports the Open. Storage copy to tape specification. The write side media server can run Net. Backup 6. 5 or later. The destination storage unit specifies the write side media server. The write side media server requests resources from the NDMP tape server and initiates and monitors the copy operation. 11

Installation 1. Install the Net. Backup for NDMP software on the Net. Backup media servers that connect to the NDMP tape server. 2. In Net. Backup, configure the NDMP tape server as an NDMP host. 3. In Net. Backup, configure NDMP host credentials for the NDMP tape server. 12

Use 1. In Net. Backup, configure the NDMP tape server storage devices. 2. In Net. Backup, configure the storage units that use the NDMP tape server storage. The storage units must be configured as NDMP storage units. 3. Create the storage server on each media server you wish to use for either backups or duplications. 13

Use (continued) Use the command: /usr/openv/netbackup/bin/admincmd/nbdevquery liststs –U This will obtain the name of the disk appliance NDMP host. If the name of the disk appliance NDMP host is different than the disk appliance storage server name, add the credentials for that NDMP host to Net. Backup. Please note that you will need to add credentials for the storage server to Net. Backup if the name of the disk appliance NDMP host and the disk appliance are the same (single host). Use the tpconfig command for this step. 14

Resources Documentation is available in the standard Net. Backup documentation (Admin Guide). Note- The output of the “nbdevquery –U” command has been changed to display the direct Copy to Tape capability and the corresponding NDMP hostname. 15

Limitations The following limitations exist: ■ The destination storage unit must be NDMP and not a Storage Unit Group. ■ You cannot make multiple copies with one copy operation. ■ Backup images are not multiplexed when written to tape. ■ If the disk appliance NDMP host does not support NDMP FSE, copy operations travel through Net. Backup media servers. 16

Troubleshooting methods are similar to standard NDMP Tape Server and BPDuplicate troubleshooting methods. 17

Logs and Messages • Key Log Messages: Log: /usr/openv/netbackup/logs/admin “NDMP Direct Copy will be attempted” -> good “NDMP Direct Copy will not be used” -> bad “DUPREADLINE: READ: NDMP_DC_ENABLED=1” -> good User initiated duplications: In the “Results” tab of the Catalog GUI: “Initiating Open. Storage Direct to Tape” -> good 18

Logs and Messages (continued) In the event of a failure, support will need to see the following: – bptm logs for read and write media servers – admin logs for duplication server (typically this is the Master server) – Vx. VL logs for mds (event id 143) and NDMP (event ids 151 and 134) 19
