9 Quest NetVault Backup Plug-in 9 for NDMP Application Notes for Dell FluidFS NAS Appliances Chapter 2: DEPLOYING AND CONFIGURING THE PLUG-IN FOR NDMP WITH DELL FLUIDFS Use Cases Prerequisites Adding the Dell FluidFS NAS Assumptions Use Cases There are two primary groups of protection options for use with the NVBU products and the Dell FluidFS NAS architecture. The first is to use NVBU as a configuration item providing services for data protection operations. This lets you implement a simple method for data protection and recovery scenarios. You can store data on a disk-based target, such as the Dell DR4000 Series appliance, or a traditional tape library. The second option lets you use NVBU as a configuration item that provides services for data-protection operations that complement NAS server replication. This lets you implement a simple method for data protection and recovery scenarios, while providing additional availability options. As with the first option, you can store data on a disk-based target, such as the Dell DR4000 Series appliance, or a traditional tape library. The following list provides examples of these two protection options: Backing up one or more NAS Containers. Backing up NAS Containers from multiple Dell NAS clusters.

15 Quest NetVault Backup Plug-in 15 for NDMP Application Notes for Dell FluidFS NAS Appliances Chapter 3: BACKING UP DATA Understanding Backup Dump Levels Backing Up Data Using Plug-in for NDMP Selecting Data for Backup Setting Backup Options Finalizing and Submitting Jobs Backing Up Replica NAS Containers Backing Up Individual Data Paths Understanding Backup Dump Levels Plug-in for NDMP supports both Full and Incremental Backups. The backup type is determined by the Dump Level, which can be set to Level 0 for a Full backup, or Levels 1 through 9 for Incremental Backups: Level 0 or Full Backup A Full Backup backs up all the data in the selected path. Level 1 through 9 or Incremental Backup Incremental Backups base themselves on the most recent lower-level Incremental Backup, and include any data that has changed or is new since the last applicable backup. For example: Level 1 Incremental Backup will include new or changed data since the last level 0 or Full Backup. Level 2 Incremental Backup will include new or changed data since the last level 1 Incremental Backup, and so on up to dump level 9. Note the following: If a directory is included in a dump level 0 backup, it is included in all future dumps even if no changes have occurred. In this instance, the directory is empty and does not contain content. However, this does not negatively affect the recovery of data. Only one dump level is maintained for each selected set of data. For example, if a Full Backup is performed after performing Level 1, Level 2, and Level 3 Incremental Backups, this resets the dump level to 0, and the subsequent Incremental Backup is based on this Full Backup. If an Incremental Backup in a series fails, the subsequent backup is based on the most recent backup of a lower level. For example, if dump level 1 is

16 16 Chapter 3 Backing Up Data completed successfully while dump level 2 fails, dump level 3 backup will be based on dump level 1. The failure of an Incremental Backup will be noted in the NVBU binary logs Backing Up Data Using Plug-in for NDMP The procedure for performing Dump Backups includes the following steps: Selecting Data for Backup Setting Backup Options Finalizing and Submitting Jobs Selecting Data for Backup You can either use the selection tree to include one or more volumes, or specify an individual data path.

All files and directories with the extension.o. The names are case-sensitive for an NFS export, but not for a CIFS share b Setting Sub-Job Options Plug-in for NDMP features the ability to generate multiple jobs for each container selected in a backup set. Quest Software recommends that you set the backups to run in parallel so that it is equal to the number of drives (virtual or physical) targeted for the data-protection backup operation. Under Sub Jobs, configure the following parameters: Number of Backups to Run in Parallel Enter the number of jobs that can run concurrently. By default, this parameter is set to zero. With this value, all jobs run in parallel, limited only by the availability of drives, network bandwidth, and other resources. To achieve the desired result, you must set the same value for each job. Delete Auto Generated Backup Jobs on Completion By default, each sub-job is included in the NVBU Jobs window, which may create confusion when you try to access the corresponding entry in this window.

For more information, refer to the Quest NetVault Backup Administrator s Guide Restoring Incremental Backups The incremental restores build on each other. To restore an Incremental Backup, you must have all the backups from Level-0 through the last backup in the backup sequence that you want to restore. To restore an Incremental Backup, perform the following steps: 1. Restore the Full or Level-0 Backup. For more information, see Restoring Dump Backups. 2. Restore each Incremental Backup in the backup sequence that you want to restore, starting with the lowest-level backup and going to the last backup that you want to restore.

27 Quest NetVault Backup Plug-in 27 for NDMP Application Notes for Dell FluidFS NAS Appliances For each dump level, follow the instructions detailed in the section Restoring Dump Backups. Important: All NDMP backups are effectively snapshots of the volume. When you restore a dump level in an increment series, it restores all the data in the saveset and at the same time delete the files present on the filer but not available in the given increment, and thus reconstructs the subtree as it was at the time of backup Renaming or Relocating Data During Restore While restoring a Dump Backup, you can rename the directories to create a copy of the data instead of overwriting of the existing versions. The Plug-in for NDMP also allows you to relocate the data to a different volume, which can be useful if the original volume is down or if you are dealing with limited bandwidth or capacity. Note: This feature is only available for savesets that were created with the Save File Information option. To rename and/or relocate a file or directory during a restore, perform the following steps: 1. Select the data for restore. For more information, see Selecting Data to Restore. 2. Right-click the file or directory to be renamed or relocated, and select Rename. 3. In the Restore Rename dialog, select the Rename To check box to activate the associated box: To rename a file or directory, enter the new name. The entity will be restored with the name specified here. To relocate data to a different volume, enter the volume name. You can also rename while relocating by specifying a new path. The volume to which you are relocating must already exist. 4. Click OK to apply changes 5. Configure the appropriate Restore Options. For more information, see Setting Restore Options. 6. Complete and submit the job. For more information, see Finalizing and Submitting Jobs.

28 28 Chapter 4 Restoring Data Restoring Data From or To a Replica NAS Container You can restore data from or to a Replica NAS Container. To restore data from a Replica NAS Container, restore the data to a regular NAS Container but make sure to select the Rename option. For more information, see Renaming or Relocating Data During Restore. Important: If Rename is not selected, the restore will fail because the Replica NAS containers are read-only. To restore data to a Replica NAS Container, promote it to a Local Container, and then submit the restore job Restoring Data to an Alternate Dell NAS FluidFS Filer With the Plug-in for NDMP, you can also restore the Dump Backups to an alternate filer, which can be useful during a server migration or a disaster recovery operation. The procedure for restoring data to an alternate NVBU Client includes the following steps: To restore the selected data to an alternate filer, perform the following steps: 1. Add the target filer as an NDMP Server. For more information, refer to the Quest NetVault Backup Plug-in for NDMP User s Guide. 2. Select the data for restore. For more information, see Selecting Data to Restore. 3. To rename or relocate data during restore, see Renaming or Relocating Data During Restore. 4. Select the Restore Options tab. 5.
