Solution: Netbackup Snapvault Management (NSVM) Symantec NetBackup utilizes Network Appliance Snapvault functionality to perform backups on NFS- mounted and/or CIFS-mapped file systems residing on NetApp filers. The Netbackup job scheduler initiates a NetApp Snapvault backup; a NetApp Snapshot copy is created on the primary NetApp storage system and is then replicated to a NetApp secondary storage system Based on the quick creation of a snapshot and a transfer of only changed blocks via NetApp Qtree Snapmirror replication, fast backups and restores can be easily accomplished from local to remote locations. Backups in the form of Snapshot copies on the primary(Remote) and secondary(Core) NetApp storage systems are managed (creation, retention, deletion) with NetBackup. All backup data stored is in file format, including all incremental backups, and each incremental backup can be viewed as a full backup image by any administrator or end-user with associated access control and security rights. Data to be restored can be quickly located with a full view into what the environment looked like at the time the backup was created, and as far back as data retention will permit. The “file system” view of backups can be accessed by end users as well, and empowers the user to perform self-restores, if the administrator permits. Standard Solution for Remote to Core provides for 30days local backup protection and 60 days remote backup retention – all backups on disk and online. 3

High-Level Process – Bringing Filer Online Network Configuration – established in System Configuration sheet Interfaces to User Network Prefer Etherchannel GbE or 100Mb (multi-mode VIF, Active-Active Trunk) Minimally Multi-Homed GbE or 100Mb (single-mode VIF, Active-Passive) Interfaces to WAN (Snapvault replication) – utilize same interfaces. Volumes and Share Creation – established through F&P Share Discovery and Backup Policy Includes NFS mount points for UNIX-based NBU instances Disable standard OnTap scheduled snapshots on non-Root volumes Limit Qtrees to 6 per volume (to control QSM snapshot limits of 255 per volume) Join filer to AD Domain Map shares Source/Target for Robocopy Process (if Filer not initially used as Primary storage) Applications running on F&P Shares should be identified in advance. Applications typically generate a higher data change rate and need to be tracked accordingly. 7

High-Level Process – NSVM Setup (continued) All NSVM SnapVault backups are managed via NetBackup for both backups and restores. NSVM Manages the Snapshot copies (retention/copies) on the Primary and Secondary) Storage Unit type is set to Disk and Disk type is set to SnapVault Media Server is appropriate selected The SnapVault server should be specified as the name of the NetApp Secondary system Specify the absolute pathname to volume as the volume that was created on the Secondary 11
High-Level Process – Setup NBU Policy Attributes Policy Type is WindowsNT Policy Storage Unit is the Storage unit setup in earlier step Check off Set # of Snapshots to keep on the primary to 30 Schedules: Name Schedule – Type (FULL) – Frequency Destination (Snapshots Only) Retention (Manages retention of copies on Secondary) – 60 Days Clients Backup Selections 12
High-Level Process – Notes: Backup Policy changes Backup policies should be aligned to remote volumes and incorporate all qtree paths within the volume having similar retention policy Any policy requirement for longer than 60day retention should have an alternate Secondary(target) vault volume defined. Currently – the “first” snapvault relationship between a new Remote site and Core, should be manually performed from NAS Admin in a create & break process. In our environment, we have seen NBU fail to create Snapvault relationships for first time Remote sites. Configurations for NBU must have the Media Server and Advanced Client components running on the same platform. Either both on Windows or both on Solaris. If UNIX is the Media Server/Advanced Client platform, then all shares must have NFS exports added. 30-Day Adjustment: Remote volumes should be originally configured with extra capacity (estimate 20%) as data change rate and snapshot consumption for the first 30 days of backups will not be known. After 30days of Snapshots/Backups are accumulated, the volumes can be re-adjusted to normal free-space levels. Flex-vols allow for dynamic growth or size reduction. 13
