Table 1: Document Revision History and Details.

OverviewThis document outlines the supporting capabilities to facilitate management of HP Backup andRecovery features on remotely deployed computer systems throughout an enterpriseenvironment. This interface provides access to HP Backup and Recovery data through standardsbased mechanisms like WMI and is accessible by other programmatic or scripting tools.



Unlimited Pages




The capabilities include enumeration of ISOs created by factory during the pre-install process,Restore Points and Full Drive Backups and any scheduled backup tasks created using the HPBackup and Recovery interface(s). Also supported are creation of new scheduled tasks, updatesand deletes of existing tasks.

HP systems are deployed with factory created images, called ISOs, on a recovery media, usuallya hidden partition on the hard drive. These images are used to restore the system to the factoryinstalled state if need be. HP Backup manageability interface provides a list of these ISOs.

SoftThinks, the vendor of HP Backup and Recovery utility, manages the backups viaconfiguration files in the system. HPQBackup instrumentation uses these configuration files toprovide access to the nature and number of backups on the system.

The scheduled tasks are also managed through configuration files. Thees tasks are managed peruser in a configuration file in the user specific application data folder. All and any of these ini filesare parsed and the backup tasks are aggregated. This aggregated task list is then replicated toall scheduler.ini files of all valid users on the system.

Required FunctionalityThis instrumentation provides the following functionality:

• Provide a public, accessible interface to the HP Backup and Recovery features.• Support listing of factory created ISOs, Full Drive Backups and Recovery points created by

HP Backup and Recovery Manager.• Support listing of all backup tasks scheduled through the HP Backup and Recovery

Scheduler.• Support creation of new tasks, exposing only a subset of the original parameter set provided

by the Scheduler and modification and deletion of existing tasks.

WMI InterfaceAll the interfaces are defined in the namespace “root\HP\BackupAnd Recovery” in the CIM objectrepository. There are 3 classes defined to expose the required functionality: HP_RecoveryPoint,HP_ScheduledBackup and HP_SchedulerService.

HP_RecoveryPointThis class is used to render the backup recovery points on the system. There are 3 types ofRecovery Points: ISOs, full drive backups and any differential recovery points. These instancesare sorted by their time of creation, from the latest to the earliest. There can be one or more ofeach type of Recovery Point. Recovery Points cannot be changed or deleted.

MOF Definition[ dynamic: ToInstance, provider("WMIProvider_HPQBackupAndRecovery"): ToInstance]class HP_RecoveryPoint{ [key, read] datetime Date; [read, ValueMap { , , , , .. }: ToInstance, Values { Unknown , "Factory ISO", "Full Partition Backup",



Unlimited Pages




"Recovery Point", Reserved }: ToInstance] uint32 Type; [read] string Location; [read] string Description; [read] uint64 Size;};

PropertiesProperty Description

Date Key property uniquely identifying the backup instance. This is the datethe backup was created.

Type Denotes the type of the backup.0: Unknown or uninitialized value.1: Factory ISO2: Full Partition Backup3: Differential Backup

Location Path where backup is created. This can be the string “Local” if thebackup is on the local drive, or UNC path if on the network.

Description Description of the backup as entered in the HP Backup Manager.

Size Size of backup in bytes.

ExampleHere are some sample instances of HP_RecoveryPoint:

instance of HP_RecoveryPoint{ Date = "20060817102544.000000-300"; Type = 1; Location = "Local"; Description = "First Full Image Backup"; Size = 8488379951;};

HP_ScheduledBackup

This class is used to manage instances of scheduled backup tasks created through the HPBackup and Recovery Scheduler interface. There can be 4 types of backup tasks, "Daily","Weekly", "Monthly" and "At System Start".

HP_SchedulerService

DescriptionThe HP_SchedulerService class provides access to methods that support the creation,modification and removal of task objects (HP_ScheduledBackup instances).

As we noticed differences in the INI files in Desktops and Mobile products, we currently supportDesktop versions only. This is accomplished by checking the version ofc:\windows\Sminst\Scheduler.exe. If this version is 1.0.4.0 or above, the methods work asintended. Otherwise they return ‘Method not supported’ errors.

MOF Definition[ dynamic: ToInstance, provider("WMIProvider_HPQBackupAndRecovery"): ToInstance]class HP_SchedulerService{ [key, read] string ServiceName; [read] string ServiceVersion; ...};

ParametersProperty Description

ServiceName Key property identifying the HP Backup and Recovery provider.

ServiceVersion String value representing the version of the HP Backup and Recoveryprovider interface.

Configuration File Format



Unlimited Pages




HP Backup and recovery utility, provided by SoftThinks, manages the full backups and recoverypoints in configuration files on the system.

Structure of NETUSERDIFF.LST/USERDIFF.LSTEach time the user creates a new recovery point in a shared folder on a network or in a folderlocated on another hard disk, the features of that recovery point are stored in a specific file,NETUSERDIFF.LST. In case of a local recovery point creation, the file is USERDIFF.LST. Thesefiles are located in the “WINDOWS\SMINST\” folder and in the root of the recovery partition.These files only list the existing recovery points. If some of them were deleted or moved toCD/DVD for example, their entries are simply removed.

The HP Backup and Recovery WMI Provider uses these files to provide programmatic access tobackup and recovery points on the system.

[Network_Path]This section contains all the network paths where recovery pointswere created for the PC. Each path corresponds to a section.

[Path_1]Login=By default, the login value is set to match the login of the current Windows userwho is logged.Password=By default the password value is set to * .Date=Creation date of the first recovery point stored in that location (format:YYYY/MM/DD HH:MM:SS).UserDiff.0=description|date (format: YYYY/MM/DD HH:MM:SS)|size (MB)UserDiff.1= description|date|sizeUserDiff.n= description|date|sizeThese values contain the information about each recovery pointstored in that location, from the first one to the last one.

[Local]This section contains all the local recovery points for the PC.

The HP Backup and Recovery WMI Provider uses these files to provide programmatic, read-onlyaccess to backup and recovery points on the system. Below is an enumeration of these backupsby the provider from CIM Studio, showing only the relevant fields.

SoftThinks’ Scheduling ProcessThe SoftThinks’ scheduling process doesn’t use Windows task scheduling but uses a silentexecutable, Scheduler.exe. Recovery Point and Entire Drive Backup creation can be scheduledupon different events (PC start, docking event, etc.) and frequencies (daily, weekly, monthly,etc.).

All the scheduled tasks are stored into an INI file, read each minute by the silent executable. ThisINI file is unique per user, and is stored in the “DOCUMENTS AND SETTINGS\<USER>\LOCALSETTINGS\APPLICATION DATA\SoftThinks” folder.

Changes in HP Backup and Recovery Manager v4.1.5 for VistaBoth Entire Drive Backups (EDB) and Recovery point backups are now tracked in a single filenamed Images.LST in the installation directory (Windows\SMINST). The provider uses this newformat if the following 2 conditions are met, the operating system is Vista and the ‘Image.Lst ver4.0’ tag is present in the beginning of the file. Otherwise it is processed in the old format.

Sample Images.LSTImage.Lst ver 4.0

Pwd=Domain=Use_DHCP=noIP_Address=Mask=Gateway=DNS1=DNS2=

Changes in Scheduler.ini include,

- DAILY backup tasks include a frequency parameter stored in the DAYS attribute

- DEST attribute is not used

- TYPE is interpreted differently. For new version, EDB = 0; RP =1 and for old version,EDB = 1; RP =0

- DEST_DIRECTORY attribute is now required for Vista. If this parameter is not specifiedfor a EDB, the HP B&R manager brings up a dialog which waits for user input. If thisparameter is provided, the EDB is created at the scheduled time without any user action.If this parameter is empty in the CreateTask() call, the WMI provider uses a default path,C:\System Recovery. Where as in the XP version if this parameter is empty, the HP B&Rmanager uses a default path and does not wait for user input.
