Applying global preferences

As the administrator, you can manage preferences that apply to all IBM Spectrum Protect Plus operations in the Global Preferences pane.

Before you begin

Only the user with administrator credentials can manage global preferences.

Restriction: The deduplication table (DDT) options are available only if you install IBM Spectrum Protect Plus interim fix 10.1.4.222 or later.

About this task

The Global Preferences pane contains default values for parameters that apply to all IBM Spectrum Protect Plus operations. The preferences are organized into three categories: application, protection, and security.

The default values for the global preferences are shown in the following table.

Table 1. Default values for global preferences
Preference Default value Unit (if applicable)
Concurrent Application Servers for Backup session 0  
vSnap Free Warn Percentage (%) 30 Percentage (%)
vSnap Free Error Percentage (%) 20 Percentage (%)
vSnap auto disable deduplication when dedup table (DDT) size exceeds resource limits Checked  
vSnap DDT size limit in GB 50 Gigabytes
vSnap DDT size limit as percentage of total memory cache 80 Percentage (%)
Group VMs by VM Group size (GB) 5120 Gigabytes
Group VMs by Number of VMs in group 20  
VMware Connectin Timeout 300 Seconds
Backup Update Interval 300 Seconds
Password Minimum Length 8 Characters

You can change the default values in the Global Preferences pane.

Procedure

  1. In the navigation pane, click System Configuration > Global Preferences.
  2. Update the values for the global preferences. To revert to the default value from a previously entered value, click the reset icon Reset icon.
    Preference Description
    Application
    Concurrent Application Servers for Backup session
    The maximum number of concurrent application servers per backup session.
    Backup (Hypervisor / Application)
    vSnap Free Warn Percentage (%)
    The percentage threshold of remaining free space in the vSnap storage pool. Warnings are displayed in the job log. For example, if a value of 10 is specified, a warning is displayed if the vSnap storage pool has 10% or less of remaining free space.
    vSnap Free Error Percentage (%)
    The percentage threshold of remaining free space in the vSnap storage pool. Errors are displayed in the job log. For example, if a value of 5 is specified, an error is displayed if the vSnap storage pool has 5% or less of remaining free space.
    vSnap auto disable deduplication when dedup table (DDT) size exceeds resource limits
    The deduplication table (DDT) is enabled by default. When either of the threshold limits defined by disk space (gigabytes) or percentage are exceeded, vSnap deduplication will be disabled. When deduplication is disabled, an alert is displayed.
    vSnap DDT size limit in GB
    The threshold in gigabytes (GB) of the vSnap deduplication table (DDT). The deduplication table (DDT) is disabled if the vSnap auto disable option is checked and the defined threshold is exceeded.
    vSnap DDT size limit as percentage of total memory cache
    The threshold as a percentage of the vSnap deduplication table (DDT) as compared to the total memory cache. The deduplication table (DDT) is disabled if the vSnap auto disable option is checked and the defined threshold is exceeded.
    Hypervisor
    Group VMs
    Virtual machines can be grouped together. The group can be defined by a count of the VMs contained or the size of the VMs contained in the group.
    VMware Connection Timeout
    The amount of time that IBM Spectrum Protect Plus waits for commands that are issued to connected vCenters to finish. If the operations do not finish within the specified amount of time, they are logged as errors. This setting applies only to VMware hypervisors.
    Backup Update Interval
    The frequency at which messages about the progress of data transfer are updated in the job log.
    Security
    Password Minimum Length
    The minimum length of passwords for IBM Spectrum Protect Plus. By default, the password has a minimum length of 8 characters, but you can specify a longer password. This value applies to all user accounts.
    Note: For VM Grouping, there are four VM groups and each VM group can have a maximum of five VMs. Each group corresponds to one destination volume (data stream). A maximum of 20 VMs (4 data streams) can be done at a time based on size calculations.
