1.1.0 Dell FluidFS – At a GlanceThe Dell FluidFS is a proprietary, scaled-out, distributed file system that adds file services to the Dell EqualLogic, Compellent, and PowerVault storage product lines. (FluidFS running on Dell PowerVault NX3500/36x0, Dell EqualLogic FS7500/76x0, and Dell Compellent FS8600 NAS Appliances is also referred to as firmware.)

The FluidFS architecture is open-standards-based, supports industry-standard protocols, and provides innovative features that relate to high availability, performance, efficient data management, data integrity, and data protection. As a core component of the Dell Fluid Data architecture, FluidFS brings differentiated value to the various Dell storage offerings. It is a network-attached storage (NAS) file system that is accessed by using Common Internet File System (CIFS) and Network File System (NFS) protocols.

The high-availability and data-integrity capabilities of FluidFS provide a solid foundation for a strong data-protection strategy. Additional elements built on this foundation include snapshots, replication, and Network Data Management Protocol (NDMP)-based backups, which protect data against localized failures, outages, and disasters.

Snapshots – Fast, point-in-time, read-only copies of NAS volumes that end users can access to recover files or directories.

Replication – Local or remote disk copy that administrators can use for disaster recovery or to recover data in the event of a service interruption.

DEPLOYING AND CONFIGURING THE PLUG-IN FOR NDMP WITH

DELL FLUIDFS Use Cases

Prerequisites

Adding the Dell FluidFS NAS

Assumptions

2.1.0 Use CasesThere 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.

Selecting Data for Backup

Setting Backup Options

Finalizing and Submitting Jobs

Backing Up Replica NAS Containers

Backing Up Individual Data Paths

3.1.0 Understanding Backup Dump LevelsPlug-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

Chapter 3Backing Up Data

16

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.

3.2.0 Backing Up Data Using Plug-in for NDMPThe procedure for performing Dump Backups includes the following steps:

Selecting Data for Backup

Setting Backup Options


3.2.1 Selecting Data for BackupYou can either use the selection tree to include one or more volumes, or specify an individual data path. For details on backing up an individual data path, see Backing Up Individual Data Paths.

To select data for a backup, perform the following steps:

1. From the NVBU Console on the NVBU Server, open the NVBU Backup window (via either of the toolbar buttons or by clicking Operations > Backup).

2. On the Selections tab, open the NVBU Client on which the plug-in is installed.

To open any node on the Selections tab, do either of the following:

Double-click the node.

Right-click the node, and select Open.

3. In the list of plug-ins, right-click NDMP Client, and select Open.


17

4. Open the target filer to display the Volumes nodes:Figure 3-1:

Selections tab

5. To select the required data, do the following:

Include NAS Containers – Select the Volumes node.

Include individual NAS Containers – Open the Volumes node, and select the NAS Containers that you want to back up.


18

3.2.2 Setting Backup OptionsThis step includes the following tasks:

Setting NDMP Backup Options

Setting Sub-Job Options

3.2.2.a Setting NDMP Backup Options1. Select the Backup Options tab.

2. Under NDMP Backup Options, configure the following parameters:Figure 3-2:

Backup Options tab

Dump Level – Select the type of backup to perform. For a Full Backup, enter 0; for an Incremental Backup, enter any level from 1 to 9 based on the previous backup sequence.

Save File Information – This option lets you browse individual files and directories while selecting data during restore. Granular restores cannot be performed if you clear this check box. Quest Software recommends that you leave this check box selected.

Exclude – Use this parameter to list all files and directories that you want to exclude from a backup. Enter the complete file path, starting with a forward slash (“/”). If you do not provide the complete path, the plug-in excludes any item that matches the entry. To specify multiple items, separate them using a comma.


19

You can use up to two wild cards per file. The wild card characters can only be used at the first or the last place in the file name. For example, if you enter “/dir1/tmp*, *.o” in Exclude, it excludes the following items:

Files and directories starting with the letters “tmp” in the directory /dir1.

All files and directories with the extension “.o”.

The names are case-sensitive for an NFS export, but not for a CIFS share.

3.2.2.b Setting Sub-Job OptionsPlug-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. To avoid this and include only a single entry for the parent job, select the Delete Auto Generated Backup Jobs on Completion check box.

3.2.3 Finalizing and Submitting JobsTo finalize and submit a backup job, perform the following steps:

1. Select the Schedule, Target, and Advanced Options tabs, and configure the required options.

These options are common to all NVBU Plug-ins. For more information, refer to the Quest NetVault Backup Administrator’s Guide.

2. In Job Title, enter a suitable title for the job.

Specify a detailed title that lets you easily identify the job for monitoring its progress or restoring data.

3. Click Submit on the toolbar, or select Accept > Submit Backup.

You can monitor the job progress via the NVBU Jobs window and view the logs via the NVBU Logs window. For more information, refer to the Quest NetVault Backup Administrator’s Guide.

To restore the entire saveset, select the root node.

To restore individual files and directories, select the target files and directories in the selections tree. The selections tree can only be browsed if the Save File Information option was selected during backup.

Figure 4-1:Selections tab

Note: You cannot omit the child-level items after selecting the parent node. The backup will fail if you do so. For selective backups, open the parent node, and select each item that you want to restore.


25

4.1.2 Setting Restore OptionsTo set the restore options, perform the following steps:

1. Select the Restore Options tab.

2. Configure the following parameters.Figure 4-2:

Restore Options

NDMP Server – This parameter can be used to restore data to a different filer. By default, the name of the original filer from which the data was backed up is displayed. Do not change this while restoring data to the same filer. To restore to a different filer, you must add it as an NDMP Client.

Direct Access Restore Mode – Select the appropriate DAR mode from the following:

Use Direct Access Restore if Possible – Select this option to perform a direct access restore if the backup was direct and the mover and the data server are capable of completing a Direct Access Restore. If these conditions are not met, a non-direct access restore will occur.

Use Direct Access Restore by Recovering Individual Files – Select this option to restore a directory and its file contents. Any empty directories in the saveset are ignored. This option must be selected if any entity has been marked as omitted in the Selections tab. Otherwise, the restore will fail.

Only Do Direct Access Restore – Select this option to force a Direct Access Restore. Note that the backup being restored must have been


26

a direct backup and a capable mover and data server must be available; otherwise, the restore will fail.

Never Do Direct Access Restore – Select this option to perform a standard Non-Direct Access Restore.

Overwrite Existing Files – Clear this option if you do not want to overwrite existing files.

Important Notes

When individual files are selected for a Direct Access Restore, their parent-level directory permissions are not restored.

When running a Direct Access Restore, NVBU organizes the restore requests into groups of 1024 files at a time. In the event that a restore selection consists of more than 1024 total files, multiple restore requests will be issued, which means multiple log entries will appear for the job.

4.1.3 Finalizing and Submitting JobsTo finalize and submit a restore job, perform the following steps:

1. Select the Source, Schedule, and Advanced Options tabs, and configure the required options.

These options are common to all NVBU Plug-ins. For more information, refer to the Quest NetVault Backup Administrator’s Guide.

2. In Job Title, enter a suitable title for the job.

Specify a detailed title that lets you easily identify the job for monitoring its progress or restoring data.

3. Click Submit on the toolbar, or select Accept > Submit Restore.

You can monitor the job progress via the NVBU Jobs window and view the logs via the NVBU Logs window. For more information, refer to the Quest NetVault Backup Administrator’s Guide.

4.2.0 Restoring Incremental BackupsThe 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

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.

4.3.0 Renaming or Relocating Data During RestoreWhile 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.




28

4.4.0 Restoring Data From or To a Replica NAS ContainerYou 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.

4.5.0 Restoring Data to an Alternate Dell NAS FluidFS FilerWith 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. In NDMP Server, enter the alternate filer name.

6. Select the appropriate DAR method.

For more information, see Setting Restore Options.




29

4.6.0 Additional Features Available on the Selections TabThis section describes the additional features present on the Selections tab of the NVBU Restore window. These features are common to all NVBU plug-ins. For more information, refer to the section dedicated to Restore functionality in the Quest NetVault Backup Administrator’s Guide.

Sorting the savesets – To sort the savesets listed on the Selections tab, select one of the following methods in the Selection Method list:

Plugin – This is the default method. The savesets are ordered according to the plugin used to generate them.

Backup Set – To sort the savesets by the Selection Set used for the backup, select Backup Set.

Job – To sort the savesets by the Job Title, select Job.

Filtering the savesets – To filter the savesets displayed on the Selections tab, configure the following parameters under Filter Options:

By Date Range – Select the By Date Range check box, and enter or select the From and To dates in the boxes provided to list the savesets generated during a given period.

Show On-line Status – Select the Show On-line Status check box to list the savesets stored on the currently online media.

Click Apply Filter to set the filter.

Searching for data items – To find a data item inside a saveset, right-click it, and select Search. Enter the item name in the Search String box, and click Search.
