자세한 설명

The New-DedupSchedule cmdlet creates a data deduplication schedule. This cmdlet returns a DeduplicationSchedule object that you can use to customize the data deduplication schedule. This cmdlet uses default settings to create a data deduplication schedule for the parameters that you do not specify.

You can create a schedule to run the following types data deduplication jobs:

-- Optimization: This type of job performs both deduplication and compression of files according data deduplication policy for the volume. After initial optimization of a file, if that file is then modified and again meets the data deduplication policy threshold for optimization, the file is optimized again.
-- GarbageCollection: This job processes deleted or modified data on the volume so that any data chunks that are no longer referenced are cleaned up. Garbage collection jobs process previously deleted or logically overwritten optimized content to create usable volume free space. When an optimized file is deleted or overwritten by new data, the old data in the chunk store is not immediately deleted. Garbage collection is scheduled to run weekly by default. Garbage collection is a processing-intensive operation, so you should allow the deletion load to reach a threshold and then manually run this job type, or schedule it for off hours.
-- Scrubbing: This job processes data corruptions it finds during data integrity validation, performs possible corruption repair, and generates a scrubbing report.
-- Unoptimization: This job undoes data deduplication on all of the optimized files on the volume. At the end of a successful unoptimization job, the server deletes all of the data deduplication metadata from the volume.

매개 변수

-AsJob

-CimSession<CimSession[]>

원격 세션에서 또는 원격 컴퓨터에서 cmdlet을 실행합니다. New-CimSession 또는 Get-CimSession cmdlet의 출력과 같은 컴퓨터 이름이나 세션 개체를 입력합니다. 기본값은 로컬 컴퓨터의 현재 세션입니다.

-Days<DayOfWeek[]>

Specifies an array of days of the week on which the server runs the data deduplication job. 이 매개 변수에 허용되는 값은 다음과 같습니다.
-- Monday
-- Tuesday
-- Wednesday
-- Thursday
-- Friday
-- Saturday
-- Sunday

-Disable

Indicates that the server disables the data deduplication schedule immediately after you create it. The server does not run the data deduplication schedule at the time that you specify in the Start parameter. After you disable a data deduplication schedule, you can use the Set-DedupSchedule cmdlet to enable the schedule.

-DurationHours<UInt32>

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.

-Full

If you specify GarbageCollection for the Type parameter:
Indicates that garbage collection jobs free up all deleted or unreferenced data on the volume. 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 Scrubbing for the Type 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.

-InputOutputThrottleLevel<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. 이 매개 변수에 허용되는 값은 다음과 같습니다.

-- None
-- Low
-- Medium
-- High

-Memory<UInt32>

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 a higher memory consumption, such as 50.

-Name<String>

Specifies a name for the data deduplication job schedule.

-Priority<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 High. For typical optimization jobs, we recommend that you set this parameter to Normal.

-ReadOnly

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

-Start<DateTime>

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]).

-StopWhenSystemBusy

Indicates that 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.

-ThrottleLimit<Int32>

이 cmdlet을 실행하도록 설정할 수 있는 최대 동시 작업 수를 지정합니다. 이 매개 변수가 생략되거나 값 0이 입력되면 Windows PowerShell®은 컴퓨터에서 실행 중인 CIM cmdlet의 수에 따라 cmdlet에 대한 최적의 제한 한도를 계산합니다. 제한 한도는 현재 cmdlet에만 적용되며 세션이나 컴퓨터에는 적용되지 않습니다.

-Type<Type>

Specifies the type of data deduplication job. 이 매개 변수에 허용되는 값은 다음과 같습니다.
-- Optimization
-- GarbageCollection
-- Scrubbing
-- Unoptimization

<CommonParameters>

이 cmdlet은 일반 매개 변수 -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer 및 -OutVariable을 지원합니다. 자세한 내용은 다음을 참조하세요. about_CommonParameters(https://go.microsoft.com/fwlink/p/?LinkID=113216).

예제

Example 1: Create a data deduplication schedule for a garbage collection job

This command creates a data deduplication schedule for a garbage collection job named OffHoursGC. The job is scheduled to run on Sundays at 8:00 at normal priority. The command specifies that the server cancels the job after 5 hours if the process has not ended.

PS C:\> New-DedupSchedule –Name "OffHoursGC" –Type GarbageCollection –Start 08:00 –DurationHours 5 –Days Sun –Priority Normal

Example 2: Create a data deduplication schedule for a scrubbing job

This command creates a data deduplication schedule for a scrubbing job named OffHoursScrub. The command starts the scrubbing job at 23:00 on 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.

PS C:\> New-DedupSchedule –Name "OffHoursScrub" –Type Scrubbing –Start 23:00 –StopWhenSystemBusy –DurationHours 6 –Days Mon,Tues,Wed,Thurs,Fri –Priority Normal

Example 3: Create a data deduplication schedule for an optimization job

This command creates a data deduplication schedule for an optimization job named MyWeekdayOptimization. The optimization job runs at a normal priority every weekday evening at 8:00. DurationHours specifies that the server cancels the job after 9 hours if the process has not ended.

PS C:\> New-DedupSchedule –Name "MyWeekendOptimization" –Type Optimization –Days Mon,Tues,Wed,Thurs,Fri –Start 08:00 –DurationHours 9
