1IntroductionThe Network Data Management Protocol (NDMP) allows you to controlthe backup and recovery of an NDMP server through a network backupapplication, without installing third-party software on the server. In anEMC VNX, the Data Mover functions as the NDMP server.This document explains how to perform NDMP backups with VNX andyour backup software. It also contains the information you need to cableand configure VNX. Use this and other VNX documentation in conjunctionwith the specific backup software documentation provided by your vendor.Chapter 2 provides more details.This document is part of VNX documentation set and is intended for thebackup system administrator implementing a backup strategy with oneor more VNX. The system administrator should be familiar with backupand restore operations and with the basic administration of VNX.Topics included are: System requirements on page 12Restrictions on page 12Cautions on page 15User interface choices on page 15Related Information on page 16Configuring NDMP Backups on VNX 7.111
IntroductionSystem requirementsTable 1 on page 12 describes the EMC VNX software, hardware, network, and storageconfigurations.Note: VNX supports NDMP version 4.0.Table 1. System requirementsSoftwareVNX version 7.1NDMP-compliant backup software running on the NDMP client. VNX for File Release Notes contain a currentlist of the EMC qualified NDMP backup software vendors.HardwareVNXNetworkDedicated network (optional)StorageCompatible tape device or tape library unit (TLU)RestrictionsNote these restrictions when configuring VNX.General restrictions12 EMC supports NDMP drive sharing only through a storage area network (SAN). VNX uses port 10000 for NDMP operations. NDMP three-way backups and restoresuse dynamic port allocation from the Data Mover. If you plan to turn on internationalization, do so before, not after creating the filesystems. Stripe size on the system can affect backup performance. For optimal backup stripesize settings on EMC Symmetrix and EMC VNX for block systems, consult the EMCE-Lab Interoperability Navigator. VNX supports a maximum of eight concurrent NDMP sessions per NDMP-Host DataMover. The backup client (DMA) should be compatible and configured to supportup to eight concurrent NDMP sessions.Configuring NDMP Backups on VNX 7.1
Introduction The Data Mover must have a minimum of 8 GB memory to run greater than four andup to eight NDMP sessions. For backups with VNX, a media interface adapter (MIA) for device connection to theAUX-0 port is required. For backups with VNX series, a small form-factor pluggable(SFP) adapter is required. Instructions on installing an MIA in VNX, or an SFP inVNX series, are documented in individual setup instructions provided with eachsystem. Make sure that no backup or restore jobs are running on the Data Mover before youissue the nas fsck –aclchk command. If a Data Mover is in ASCII mode and you back up a file system with asciifilter off,the filename with international characters cannot be recovered if the asciifilter isturned on during the restore. It is recommended that all Data Movers be configuredto use UNICODE rather than ASCII mode.Configuring and Managing CIFS on VNX provides information on how to check andchange the Data Mover mode. Using International Character Sets on VNX for File providesinformation on enabling Unicode on a new VNX.Restrictions for TLU connections Do not connect the Control Station to the TLU. Only Data Movers can be connectedto the TLU. For each TLU SCSI connection, it is recommended to attach no more than two tapedrives. Connecting multiple Data Movers to the same TLU is supported. The TLU can have multiple SCSI host connections. The TLU can also have FibreChannel connections. The TLU documentation offers installation and configurationinformation. You cannot daisy chain to the TLU any of the Data Mover’s system SCSI connections. The ability to connect a Data Mover to a TLU depends on the number of SCSI portson a Data Mover. Some older models of a Data Mover can have only two SCSI ports,which are required for system connectivity and redundancy. These system SCSI portsshould not be used for TLU connections. If an NDMP-Host Data Mover fails over to its standby, you must physically connectthe Data Mover’s TLU cable to the standby, and restart the backup. You could alsoneed to reconfigure the backup software with the appropriate address.Restrictions13
IntroductionNDMP restrictions NDMP does not support the Archive Bit method. Only the Date/Time stamp methodis supported. The special wildcard characters, as well as the include/exclude options, are notsupported. To back up multiple directories, include all directories in the file/directorylist when creating the backup job. You can use filtering to exclude specific files anddirectories from a backup, as described in Exclude directories or files from backupby using filtering on page 86. NDMP does not follow symbolic links among file systems. Therefore, an NDMPbackup does not include a symbolic link's target file system. Managing a MultiprotocolEnvironment on VNX contains more information on symbolic links. NDMP backups and restores of iSCSI LUNs are not supported. You cannot restore deduplicated files from an NDMP backup performed on a systemthat is running Celerra Network Server version 5.6.47 or later to a system runningversion 5.6.46 or earlier. You cannot restore a file system that contains deduplicated files from a VBB backup,performed on a system that runs Celerra Network Server version 5.6.43 or later, to asystem running version 5.6.42 or earlier. Do not convert a raw file system (rawfs) that is created for NVB full destructive restoreto uxfs file system, until the restore operation is completed successfully. When you create a new storage by using IBM Tivoli and NDMP to disk with CelerraNetwork Server version 5.6, do not specify the barcode prefix in lowercase letters.IBM Tivoli does not support barcode prefix in lowercase.If you do not specify the barcode prefix, it will be generated in uppercase letters. As of Celerra Network Server version 5.6.40.3, the md5 encrypted password(NDMP.md5 1) is enabled by default while creating the NDMP local user account.If you did not use md5 encryption when the NDMP user account was created, backupscan fail after upgrading to Celerra 5.6.40.3 or later.If this occurs, you can either change the md5 parameter value to "0", or create theNDMP user account with the md5 password option. Parameters Guide for VNX for Fileprovides information about the NDMP.md5 parameter.14Configuring NDMP Backups on VNX 7.1
IntroductionCautionsIf any of this information is unclear, contact your EMC Customer Support Representativefor assistance: If a failover occurs during a backup, you must directly connect the tape drive to the newData Mover and restart the backup. You could also need to reconfigure the backupsoftware. Do not connect a standby Data Mover to the TLU by means of a SCSI connection. Thiswill cause the backup to fail and could cause tape contention. Do not unmount a target file system during a backup or restore operation. If you change the network zoning configuration, where relevant, propagate changes tothe consistent binding table and adjust the backup software to reflect the new zoningconfiguration. In VNX for block environment, before you run the server devconfig -create command,verify that all paths to the Data Mover are active and no LUNs are trespassed. You cannot back up tree quotas from the original file system and restore them to adifferent file system because the action is not supported. To preserve tree quotas whenrestoring, the target file system must be the same destination as the original file system,and it must have tree quotas enabled on it.User interface choicesVNX offers flexibility in managing networked storage that is based on your supportenvironment and interface preferences. This document describes how to configure NDMPbackups by using the command line interface (CLI). You can also perform some of thesetasks by using one of the VNX management applications: EMC Unisphere Celerra Monitor Microsoft Management Console (MMC) snap-ins Active Directory Users and Computers (ADUC) extensionsYou cannot use the Unisphere software for: Creating NDMP user accounts Viewing PAX statistics when performing backupsCautions15
