IBM C1000-082 - IBM Spectrum Protect V8.1.9 Administration

According to the IBM Spectrum Protect documentation1, one statement that is true regarding client-side and server-side deduplication is B. Client-side deduplication generally eliminates the deduplication workload on the server for that particular client workload. This statement means that when client-side deduplication is enabled, the backup-archive client removes redundant data before sending it to the server, which reduces the amount of data that needs to be processed by the server.

According to the IBM Spectrum Protect documentation1, three processes that can be used to prepare for disaster recovery are:

Protect storage pool: This process creates a copy of a primary storage pool on another server or device. The copy can be used to restore data if the primary storage pool is damaged or lost.

Node replication: This process replicates data from one server node to another server node. The replicated data can be used to recover client data if the source server node is unavailable.

Backup storage pool: This process backs up data from a primary storage pool to another storage pool. The backup storage pool can be used to restore data if the primary storage pool is corrupted or deleted.

an administrator needs to configure client management services to 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.

According to the IBM Spectrum Protect™ and Spectrum Scale™ Integration Guide1, one option that should be specified when configuring a storage agent for optimal LAN-free backup and restore performance is LANFREESHM YES. This option enables the use of shared memory for communication between the storage agent and the server, which can improve throughput and reduce CPU usage.

According to IBM documentation1, to define a server for server-to-server communications, you need to use the DEFINE SERVER command and specify three parameters: SERVERNAME, HLADDRESS, and LLADDRESS. The SERVERNAME parameter is the name of the server that you are defining. The HLADDRESS parameter is the high-level addressof the server that you are defining. The LLADDRESS parameter is the low-level address of the server that you are defining.

This means that, by default, files from different clients are grouped together in storage pool volumes to optimize space utilization. This information is available in the IBM Spectrum Protect for AIX [1]: Administrator's Reference, which is one of the official documentation resources for this product.

According to IBM Spectrum Protect V8.1.9 documentation1, automatic client deployment is a feature that allows the IBM Spectrum Protect server to automatically upgrade backup-archive clients on client workstations. The existing backup-archive clients must be at version 6.4.3 or later.

To use this feature, you must download the software packages for the client platforms that you want to upgrade from the IBM Support website23. You can use the Operations Center or command line interface to specify where to store these packages on the server and how to distribute them to clients1.

According to IBM documentation1, the client option TXNBYTELIMIT specifies the number of kilobytes that the client program buffers before sending data to the server. This option affects how often data is sent to the server during backup and archive operations.
