C1000-082 IBM Spectrum Protect V8.1.9 Administration Questions and Answers

According to the IBM Spectrum Protect documentation 1 , one command that defines or deletes all drives and their paths for a single library in one step is  PERFORM LIBACTION with SANDISCOVERY=ON . This command performs a SAN discovery operation on a SCSI or VTL library and automatically defines or deletes all drives and paths that are associated with the library.

To specify whether the client acceptor daemon service (CAD) manages the scheduler, you need to add the MANAGEDSERVICES option in  the client system-options file  on Linux 1 .  The client system-options file is named  dsm.sys  by default 1 .  You can use this option to reduce the number of background processes on your workstation by letting the client acceptor daemon start and stop the scheduler process as needed for each scheduled action 2 3 .

The journal engine service monitors changes to specified files and directories and records information about the changes in a journal database. When a backup is performed on a file system that is being monitored by the journal engine service, IBM Spectrum Protect uses the information in the journal database to perform a journal-based backup. This allows IBM Spectrum Protect to quickly identify and back up only the files that have changed since the last backup, reducing the amount of data that needs to be backed up and speeding up the backup process.

According to IBM Spectrum Protect V8.1.9 documentation 1 , journal-based backup is an alternate method of backup that uses a change journal maintained by the IBM Spectrum Protect journal service process. To support journal-based backup, you must configure the journal engine service using the dsmcutil command or the client GUI setup wizard.

The incremental command backs up all new or changed data in the locations that you specify, unless you exclude them from backup services 2 .  If the journal engine service is installed and running when the incremental command is used for a backup, it performs a journal-based backup on file systems that are being monitored by the journal engine service 1 .

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 IBM documentation 1 , the SESSIONSECURITY parameter of TRANSITIONAL is used when you want to use the existing communication protocol while you update your IBM Spectrum Protect software to V8.1.2 or later. This is the default value.

According to the web search results, perfmon is a performance monitoring tool that is integrated with the  Microsoft Windows  operating system 1 2 3 4 .  It allows you to look into the performance of your system and the applications that are running on it 2 .

According to IBM documentation 1 , the UPDATE SCHEDULE command takes two forms, depending on whether the schedule applies to client operations or administrative commands. Within these two forms, you can select either classic or enhanced style schedules.

According to IBM documentation 1 , clients at-risk in the Operation Center are  clients without successful backup based on the policy . The Operation Center shows a large number of “At Risk” clients even though backups are completing normally if the number of “At Risk” clients is larger than the number of failed client backups.

According to IBM documentation 1 , 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 address of the server that you are defining. The  LLADDRESS  parameter is the low-level address of the server that you are defining.

To restore a file that was inadvertently deleted, you need to have a backup copy of the file available. The  RETEXTRA  option in a backup copy group specifies that extra versions of files are kept even if the files are deleted from the active file system. This means that older versions of files are retained beyond their normal retention period, allowing you to restore files that were inadvertently deleted.

According to IBM documentation 1 , the REPAIR STGPOOL command is a restricted command that requires authorization from an approval administrator.  An approval administrator is an administrative user who has been designated as an approver for restricted commands by using the SET APPROVALADMIN command 2 .

According to IBM documentation 1 , 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.

According to IBM Spectrum Protect Plus overview 1 , you need  the object agent  to accept data from IBM Spectrum Protect Plus.  The object agent is a component of IBM Spectrum Protect that enables you to back up and restore data on cloud object storage devices 1 .  You also need to configure the offload settings on IBM Spectrum Protect Plus and create an S3 consolidation pool on IBM Spectrum Protect 2 .  For more details, you can refer to the IBM Spectrum Protect V8.1.9 documents 3 4 5 .

According to IBM documentation 1 , the purpose of the  SET REPLSERVER  command is to set the name of a target replication server for a source replication server. The command has two parameters:  SERVERNAME  and  REPLSERVER . The  SERVERNAME  parameter is the name of a source replication server that you want to replicate data from. The  REPLSERVER  parameter is the name of a target replication server that you want to replicate data to.

According to IBM’s documentation 1 2 , client-side encryption is a method of encrypting data before it is sent to the server for backup or archive operations. Client-side encryption uses a password that is entered by the user to generate an encryption key.  The password needs to be confirmed when encrypting the file for backup, and also needs to be entered when performing restores of encrypted files 1 2 .

Client-side encryption satisfies all the requirements of encrypting data during transmission and storage, because:

It prevents data from being read during transmission, because the data is encrypted before it leaves the client system 3 .

It prevents data from being read once written in the storage pool, because the data remains encrypted on the server and can only be decrypted with the password that is known by the user 3 .
