Description

The Set-DedupSchedule cmdlet changes configuration settings for one or more data deduplication schedules.

Examples

Example 1: Change settings of a data deduplication schedule for a garbage collection job

$params = @{
    Days          = 'Sunday'
    DurationHours = 5
    Name          = 'OffHoursGC'
    Priority      = 'Normal'
    Start         = '08:00'
    Type          = 'GarbageCollection'
}
Set-DedupSchedule @params

This command changes the settings of a data deduplication schedule for a garbage collection job named OffHoursGC. The job is scheduled to run every Sunday at 08:00 with Normal Priority. The command specifies that the server cancels the job after 5 hours if the process has not ended.

Example 2: Change settings of a data deduplication schedule for a scrubbing job

$params = @{
    Days = Monday,Tuesday,Wednesday,Thursday,Friday
    DurationHours = 6
    Name = "OffHoursScrub"
    Priority = Normal
    Start = 23:00
    StopWhenSystemBusy = $true
    Type = Scrubbing
}
Set-DedupSchedule @params

This command changes the settings of a data deduplication schedule for a Scrubbing Type job with a Name of OffHoursScrub. The command starts the scrubbing job at 23:00 every day Monday through Friday at normal priority. The StopWhenSystemBusy parameter specifies that the server stops the job when the system is busy and retries later. The DurationHours parameter specifies that the server cancels the job after 6 hours if the process has not ended.

Example 3: Change settings of a data deduplication schedule for an optimization job

$params = @{
    Days          = @(
        'Monday'
        'Tuesday'
        'Wednesday'
        'Thursday'
        'Friday'
    )
    DurationHours = 9
    Name          = 'MyWeekendOptimization'
    Start         = '08:00'
    Type          = 'Optimization'
}
Set-DedupSchedule @params

This command changes the settings of a data deduplication schedule for an optimization job named MyWeekdayOptimization. The optimization job runs at a Normal Priority every weekday evening at 08:00. DurationHours specifies that the server cancels the job after 9 hours if the process has not ended.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:	CimSession[]
Aliases:	Session
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Cores

Specifies the maximum percentage of physical cores that a job uses.

Type:	UInt32
Aliases:	MaximumCoresPercentage
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Days

Specifies an array of days of the week on which the server runs the data deduplication job. The acceptable values for this parameter are:

• Monday
• Tuesday
• Wednesday
• Thursday
• Friday
• Saturday
• Sunday

Type:	DayOfWeek[]
Accepted values:	Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DurationHours

Specifies the number of hours that the server runs the task before canceling it. The value 0 indicates that the server runs the job to completion. This cmdlet safely stops a data deduplication job and does not affect the files that the server is processing when it cancels the job.

Type:	UInt32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Enabled

Indicates whether a data deduplication schedule is enabled.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Full

Indicates that garbage collection jobs free up all deleted or unreferenced data on the volume, if you specify the value GarbageCollection for the Type parameter. If you do not specify this parameter, garbage collection jobs free up space after a system threshold of delete data is exceeded. We recommend that you run garbage collection regularly without specifying this parameter, and then once a month specify this parameter and run garbage collection again.

If you specify the value Scrubbing for the Type parameter, this parameter indicates that scrubbing jobs validate the integrity of all data on the volume. If you do not specify this parameter, the scrubbing job validates only critical metadata and data integrity issues that data deduplication previously encountered. We recommend that you run scrubbing regularly without specifying this parameter, and then once a month specify this parameter and run scrubbing again.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-InputObject

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

Type:	CimInstance[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-InputOutputThrottle

Specifies the amount of input/output throttling applied to the deduplication job. Throttling ensures that deduplication does not interfere with other I/O intensive processes. The acceptable values for this parameter are: integers from 0 to 100. If you specify this parameter and the InputOutputThrottleLevel parameter, InputOutputThrottle takes precedence.

Type:	UInt32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-InputOutputThrottleLevel

Specifies the amount of I/O throttling that the job provides to ensure that the job does not interfere with other I/O intensive processes. The acceptable values for this parameter are:

• None
• Low
• Medium
• High

Type:	InputOutputThrottleLevel
Accepted values:	None, Low, Medium, High, Maximum
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Memory

Specifies the maximum percentage of physical computer memory that the data deduplication job can use.

For optimization jobs, we recommend that you set a range from 15 to 50, and a higher memory consumption for jobs that you schedule to run when you specify the StopWhenSystemBusy parameter. For garbage collection and scrubbing jobs, which you typically schedule to run in off hours, you can set higher memory consumption, such as 50.

Type:	UInt32
Aliases:	MaximumMemoryPercentage
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Name

Specifies the name of a data deduplication job schedule.

Type:	String[]
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Priority

Sets the CPU and I/O priority for the optimization job that you run by using this cmdlet. For jobs that you run when you specify the StopWhenSystemBusy parameter, we recommend that you set this parameter to Low. For typical optimization jobs, we recommend that you set this parameter to Normal.

Type:	Priority
Accepted values:	Low, Normal, High
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ReadOnly

Indicates whether the scrubbing job processes and reports on corruptions that it finds but does not run any repair actions.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Start

Specifies a time to start this job. The default value is 1:45am.

Type the date in a format that is standard for the system locale, such as dd-MM-yyyy (German [Germany]) or MM/dd/yyyy (English [United States]).

Type:	DateTime
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-StopWhenSystemBusy

Indicates whether the server stops the job when the system is busy and retries later. We recommend that you specify this parameter when you set a low priority for the job.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:	Int32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Type

Specifies an array of types of data deduplication jobs. The acceptable values for this parameter are:
