Overview
You can change CrashPlan app performance settings in the CrashPlan console to specify the maximum amount of resources allocated to the CrashPlan app on user devices. You can set performance for when users are present at their devices or away from their devices. This article explains the app performance settings and how to configure them.
Considerations
- If administrators do not lock the app performance settings in the CrashPlan console, CrashPlan app users can change the performance settings in the CrashPlan app.
- The method used to detect away/present status varies by operating system and CrashPlan app version. For complete details, see How does the CrashPlan app detect away and present settings?
Steps
- Sign in to the CrashPlan console.
- Select Administration > Environment > Organizations.
- Select the organization for which you want to change performance.
- From the action menu in the upper-right corner, select Device Backup Defaults.
The General tab appears. - If selected, deselect Use device defaults from parent.
- Change the following performance settings:
-
When user is away, use up to
Enter the maximum percentage of resources to devote to CrashPlan app processes when users are not actively using their devices. -
When user is present, use up to
Enter the maximum percentage of resources to devote to CrashPlan app processes when users are actively using their devices.
-
When user is away, use up to
-
Push or lock the setting:
-
Push
Send the settings to devices in the organization, but still allow users to change the settings in the CrashPlan app. -
Lock
Send the settings to devices in the organization, and lock the settings so that users are unable to change them in the CrashPlan app.
-
Push
- Select Save.
About app performance settings
Administrators can configure performance settings in the General tab of the device backup default settings of the CrashPlan console with these settings:
- When user is away, set performance to__ %
- When user is present, set performance to __ %
Setting When user is away to a higher setting than When user is present balances performance so that more are dedicated to CrashPlan app requests when users are away from their devices than when users are using their devices.
What does "performance" mean in CrashPlan?
App performance settings apply to the amount of working time dedicated to CrashPlan app work, not to total resources of the computer. The CrashPlan app always runs as a background service, so setting app performance to 100% will not adversely affect the performance of your device.
The processing time of the CPU is measured in instruction cycles. When you set the maximum percent for performance, you are specifying that the CrashPlan app is allowed use as much of the CPU capacity as it needs for up to X% of the total available cycles. For example, if When user is present, use up to is set at 40% performance, the CrashPlan app can use the CPU up to 100% capacity, but only up to 40% of the time it sends requests to the CPU. The remaining 80% of the time, other process requests use the CPU. This allows the CrashPlan app to work as efficiently as possible when it requests CPU resources, but limits the amount of time it ties up the CPU.
If you set the maximum allowed percentage to 100%, the CrashPlan app can use all available CPU capacity for 100% of the time it sends requests. Other processes can still make requests and have them processed by the CPU when it has available instruction cycles, it's just that the CrashPlan app is allowed to use up to 100% of the available instruction cycles when it requests them.
