According to the IBM Spectrum Protect for Mail documentation1, it backs up Exchange Server databases by using Microsoft VSS. 

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.

The RANDOMIZATION parameter sets randomized start times within the startup window of each schedule for clients by using the client-polling scheduling mode1. A startup window is the start time and duration during which a schedule must be initiated. The RANDOMIZATION parameter does not affect other scheduling modes such as server-polling, client-prompted, or server-prompted.

According to the web search results, a retention set is a point-in-time collection of inactive client backup data for a set of nodes or virtual machines1. A retention set can be used to meet long-term data retention requirements without having to store multiple copies of the data on the server1.

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.

The Client API allows applications to directly access the storage services provided by IBM Spectrum Protect, whereas the other options are not necessary for a custom Linux install. However, it's important to note that the specific components required for a custom install may vary depending on the individual needs and requirements of the installation.

According to the IBM Spectrum Protect V8.1.9 documentation, the option to restore the most recent backup version of a file, even if the backup is inactive, is the LATEST option. This option will restore the last backup version of a file regardless of the backup's status.

Here is an example command using the LATEST option to restore a file:

restore /home/user1/testfile -latest

This command will restore the most recent backup version of the file "testfile" regardless of whether the backup is active or inactive.

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.
