About catalog search

The NetVault Backup Server version 12.0 and later running on Windows and Linux operating system supports catalog searching. The NetVault Backup catalog search service provides fast-search capabilities for the metadata (name, mod date, type etc) of items backed up by NetVault Backup. Catalog search provides search capabilities for the tags (Filename) based on string data-type.

Catalog search results provides the following information:

•
List of records matching the search query.
•
Result paging: Retrieve results in pages for large result sets.
•
Result collapsing: If a file is backed up multiple times in different backups, then only one match for that file is displayed with the option to drill- down to find the specific backups holding the file.
•
Faceting and search narrowing: Displays the number of search results matching a particular facet. This information is available by applying filters to the search results. For example, the number of results from a particular plug-in or machine.

The following plug-ins support catalog searching:

•
NetVault Backup Plug-in for FileSystem
•
NetVault Backup Plug-in for VMware
•
NetVault Backup Plug-in for Hyper-V
 

Prerequisites

Before you start configuring the NetVault Backup, verify that the following requirements are met:

•
Catalog search reserved RAM size (For Windows and Linux) must not be more than 50% of the physical RAM. For low memory systems (i.e. 8 GB or less), Quest recommends to set the reserved RAM size to no more than 2 GB.
•
Virtual memory (only for Linux) mmap counts on Linux is 65530, which is a default operating system limit on mmap counts. Change this value to 262144 using the following command:
sysctl -w vm.max_map_count=262144
To verify the mmap count after rebooting, run the command sysctl vm.max_map_count
•
Catalog search port requirement: 9200 and 9300.
•
Elasticsearch version 6.2 is compatible with many NetVault Backup Server supported platforms. For more information, see https://www.elastic.co/support/matrix.
 
* 
NOTE: Catalog search installation is not supported on Debian 7 or lesser version.
•
Determine NetVault Backup catalog search Linux user account.
 
* 
NOTE: Sometimes, due to policy restrictions on your system, the NetVault Backup on Linux operating system is unable to create new catalog search Linux user account automatically.
While installing NetVault Backup catalog search, you can select any of the following options for catalog search Linux user account:
•
Allow NetVault Backup to create catalog search Linux user: The default option to allow NetVault Backup to create Catalog search Linux user account automatically (default value: netvault-catalog on Linux).
•
Linux user name: Create a new Linux user account by referring to the corresponding operating system guide. Ensure that the specified catalog search Linux user belongs to the group <user name>. Create the group with the same name as of the Linux user name and add the user into the same group.
 
* 
NOTE: While creating a catalog search Linux user account, do not use ‘root’ user in the field ‘Linux use name’. In NetVault Backup, catalog search cannot run by a ‘root’ user due to restrictions from Elasticsearch component.
 
* 
NOTE: Catalog search sets the system level JAVA_HOME environment variable that is required for Elasticsearch. Hence, the other java applications may not work. It is assumed that the NetVault Server is a dedicated server.

Configuring catalog search

To enhance searching for files in savesets, you must install and configure the catalog search service on NetVault Backup Server running on Windows or Linux operating systems.

To install and configure the catalog search:

By default, ‘admin’ is used as the password if this field is kept empty during catalog search installation.

 

Confirm Catalog Search Password

Type the password again for confirmation.

 

Existing Linux User (for Linux only)

For Linux operating system, type the existing Linux user name. Do not use the ‘root’ as a user name. For more information, see Prerequisites.

 

Database Directory

Click Browse to select the database directory for catalog search:

•
‘Database Directory’ drawer is displayed on the right- side of the page.
•
Open the parent node, browse through the directory tree, and locate the directory to store the catalog search database.
•
The selected directory path is displayed in the text box.
•
Click OK.

 

Snapshot Directory

Click Browse to select the location to store the catalog search database backup.

•
‘Snapshot Directory’ drawer is displayed on the right- side of the page.
•
Open the parent node, browse through the directory tree, and locate the directory to store the catalog search database backup.
•
The selected directory path is displayed in the text box.
•
Click OK.

 

Log Directory

Click Browse to select the location to store the catalog search logs.

•
‘Log Directory’ drawer is displayed on the right- side of the page.
•
Open the parent node, browse through the directory tree, and locate the directory to store the catalog search logs.
•
The selected directory path is displayed in the text box.
•
Click OK.

Configuration

Reserved RAM Size (GB)

This is the amount of RAM that the catalog search service attempts to pre-allocate before it starts. If the RAM isn’t available the service won’t start.

By default, the value is set to 1GB. Type or select the required RAM size. For systems with Large RAM size, a higher value is recommended (2 – 16 GB, based on the item backup rate and availability of RAM, limited by the restrictions mentioned in the Prerequisites section).

 

Maximum simultaneously active catalog workers

By default, 5 concurrent catalog workers can run on the server.

To change the number of catalog workers that can be run in parallel at any time, type or select the new value.

Minimum value: 1

Maximum value: 20

 

Add pre-existing and scanned backups to catalog

Select this check box to include the pre-existing and scanned backup jobs for catalog searching. By default, the check box is clear.

 

Include backups with offline indexes

Select this check box to include the backup jobs with offline indexes for catalog searching. By default, the check box is clear.

You can select this option only if the option Add pre-existing and scanned backups to catalog is selected.

 

Offline index load wait (Minutes)

This is the amount of time the catalog search service will wait for an offline index for a pre-existing backup to be loaded. If the media manager doesn’t load the offline index within this wait time, cataloging of this pre-existing backup will be temporarily skipped. Eventually, the skipped pre-existing backup will be cataloged, with the timing depending on how many other pre-existing backups are available for cataloging.

Type or select the duration (in minutes) to wait for loading the offline index during catalog indexing. By default, the minimum value is set to 10 minutes.

 

Startup offline index load wait (Minutes)

This is the minimum time from the last NetVault Backup start time before the catalog search service requests the media manager to load an offline index. This delay from the last NetVault Backup start is required to allow the media manager to complete its device scan to determine which devices are available. If a device is unavailable or hasn’t been scanned to determine its availability at the time of receipt of an offline index request, the media manager fails the request without trying to load the offline index.

Type or select the duration (in minutes). By default, the minimum value is set to 10 minutes.

 

Restrict the age of backups added to the catalog

Select this check box to restrict the pre-existing backup jobs for catalog searching.

By default, the check box is clear.

You can select this option only if the option Add pre-existing and scanned backups to catalog is selected.

 

Add backups completed on and after

To include the backup jobs completed on and after a specific date in the catalog search, type the date, or click the button next to the box, and select the date.

 
* 
NOTE: You cannot change the directories (Database Directory, Snapshot Directory, and Log Directory) after catalog search configuration. If you must change the directories, you can uninstall the catalog search and then reinstall using different directories. However, you have to re-catalog your existing backups, which can take a long time.
