According to IBM's documentation1, the QUERY OCCUPANCY command shows where client file spaces are stored and how much space they occupy. The information displayed by this command includes:

The node name

The file space name

The storage pool name

The device class name

The number of files

The physical space occupied

The logical space occupied

The deduplication ratio

an administrator needs to configureclient management servicesto configure client diagnostics from the Operations Center. The client management service enables the IBM Spectrum Protect server administrator to view diagnostic information from the Operations Center.

The command that helps protect the IBM Spectrum Protect server in case of a database failure is 'BACKUP DB.'

Backing up the Spectrum Protect database protects against data loss due to hardware failure[1], software problems, or other emergencies that might cause a total loss of the database. The BACKUP DB command creates a backup copy of the IBM Spectrum Protect database.

If a database failure occurs, the backup can be used to restore the database to a known state.

It is important to periodically perform backups of the IBM Spectrum Protect server database to ensure that the data is protected in the event of a failure[1]. Detailed instructions for performing backups can be found in the IBM Spectrum Protect V8.1.9 documentation.

According to IBM documentation1, one of the requirements for restoring individual files from an NDMP backup with the backup/archive client GUI is that a Table of Contents (TOC) must be created during the backup. The TOC contains file-level restore information that is used by the backup/archive client GUI to display and select files for restore. The TOC is stored in a different storage pool from the one where the backup image is stored.

According to IBM Spectrum Protect V8.1.9 documentation1, a system administrator has the highest level of authority in IBM Spectrum Protect. A system administrator can issue any administrative command and has authority to grant or revoke privileges for other administrators.

The privilege class for a system administrator isSYstem1. The other privilege classes such as root, administrator, or superuser are not valid for IBM Spectrum Protect.

In IBM Spectrum Protect (formerly known as Tivoli Storage Manager), the system privilege class can perform all administrative functions. The system privilege class includes the following permissions:

SYSOP: System operations

AUDIT: Auditing operations

SECURITY: Security operations

NODEADDP: Add nodes

NODEDELP: Delete nodes

MGMTCLAS: Management class operations

DEVCLASS: Device class operations

STGPOOL: Storage pool operations

LIBRARY: Library operations

QUERY: Query operations

BACKUP: Backup and archive operations

RESTORE: Restore operations

ARCHIVE: Archive operations

RESTOREVM: Restore virtual machine operations

PROXY: Proxy operations
