Before you deploy a NetVault system, review the following topics:
The first step in deploying NetVault is to identify the server and client machines:
• |
NetVault Server: This machine hosts the server version of NetVault. |
• |
NetVault Clients: These machines host the client version of NetVault and serve as the backup and restore targets. |
The database directory contains the following subdirectories:
• |
install: This directory contains the modules file, which includes a list of NetVault modules installed on the server and client machines. The install directory is small in size. |
• |
lv: This directory contains one license file called productlicenses.xml, which is where the install license is added. The directory is small in size. |
• |
MediaDatabase: This directory stores the media records and backup indexes. The MediaDatabase directory grows to be rather large as you use the NetVault system. To estimate space requirements for the MediaDatabase directory, see Database size calculation. |
• |
pgsql: This directory stores the backup and restore job records. The space requirement for this directory depends on the content of the jobs. When calculating space requirement for the NetVault Database, consider adding 10 percent of the MediaDatabase size for this directory. |
For estimating space requirements for the MediaDatabase, consider the following:
• |
Approximate number of files and directories backed up per machine: Each file or directory that is included in a backup requires an average number of bytes for an index entry in the NetVault Database. This average is based on a formula of 71 bytes plus the average number of characters contained in the filenames of the files that make up a target file system. |
• |
Number of generations of each backup retained: Each generation is a separate instance of a file or directory backup. For example, if the same file is backed up seven times using the default backup settings, there are seven generations of the file stored on the media and indexed in the NetVault Database. |
Approximate number of files and directories backed up per machine |
During installation, the NetVault Server and Client machines are assigned a name and password:
• |
NetVault machine name: The NetVault machine name is used to identify the server and client machines in a NetVault Domain. |
• |
NetVault machine passwords: The NetVault machine password is used while adding a client to the server. The machine password can contain a maximum of 100 characters. It cannot contain the characters: \ and spaces. |
NOTE: While installing NetVault in GUI mode or Text mode, in the Machine Password or PostgreSQL Database Superuser Password, do not escape any special character. However, while using the CLI options like nvpassword or nvpgdbpasswd, escape the special characters such that the desired password is properly received by the CLI. For example, if the password is <>&#|/"':*.-`()[]{}$@? then, enter it as the following:
On Linux shell: \<\>\&#\|/\"\':\*.-\`\(\)[]{}\$@?
On Windows command prompt: "<>&#|/""':*.-`()[]{}$@?". |
• |
Allow NetVault to create PostgreSQL Linux user: The default option to allow NetVault to create PostgreSQL Linux user account automatically (default value: netvault-pgsql on Linux). |
• |
Linux user name: Create a new Linux user account by referring to the corresponding operating system guide. Ensure that the specified PostgreSQL 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. |
Before you start the installation procedure, verify that the following requirements are met:
• |
Review the release notes and compatibility guide: Before you start the installation procedure, review the Release Notes thoroughly. The Release Notes may contain important information regarding the installation and use of NetVault. |
• |
Review the OS requirements for NetVault Server and Client: The NetVault Server can be installed on Linux and Windows. The NetVault Client can be installed on Linux and Windows operating systems. |
• |
Review the NetVault Server Sizing Guide: This guide provides information about system requirements for the NetVault Server. You can download this guide from https://support.quest.com/technical-documents. |
• |
Set OS permissions: Set appropriate OS permissions on the target machines to allow users to install software components. |
• |
Set the executable permission to the Linux and UNIX installers: On Linux and UNIX platforms, set the executable permission to the installers. |
• |
Select multiuser runlevel on Linux and UNIX: On Linux and UNIX platforms, boot into multiuser mode. |
• |
Set user permission (umask) on Linux and UNIX: On Linux and UNIX platforms, do not change the default umask value for the root user. The default value is 022. Setting umask to a value other than 022 (for example, 077) can cause job failures if the plug-in users are unable to access the NetVault files. |
• |
Verify the SELinux (Security-Enhanced Linux) policy: If SELinux is enabled using the default “targeted” policy, NetVault processes do not cause any Access Vector Cache (AVC) denial problems. If a strict or custom policy is implemented, ensure that NetVault processes can run in unconfined mode. |
• |
Disable the anti-virus software: We recommend that you disable the anti-virus software before installing or upgrading NetVault. If you do not disable the anti-virus software, the installation process may conflict with the anti-virus software and various NetVault operations may fail to function properly after installation. |
• |
Verify TCP/IP connectivity: NetVault requires good TCP/IP connectivity between the server and client machines. To use name resolution, a host name must resolve to a unique IP address. |
• |
Check storage device connections: Verify that the storage devices are properly connected and functional. You can check the device connections using any native OS tool for minimal backup operations on the device. |
• |
Configure “ulimit” variables on Linux and UNIX: On Linux and UNIX, the default size limitation for various variables may conflict with the NetVault installation. For example, the default setting for the file size (blocks) and virtual memory (kbytes) variables may be too low for NetVault. |
• |
Load the SCSI Generic (sg) driver on Linux-based machines: On Linux-based systems, NetVault uses the sg driver to connect to the tape devices. On machines with locally attached tape devices, either manually load the sg driver or edit the kernel configuration file to automatically load this driver at boot time. |
• |
Confirm required libraries on Linux platforms: When installing NetVault on a Linux platform, verify that glibmm and libicu libraries are present on the system. |
