Detailed Description

The Update-DPMPGSet cmdlet updates and saves changes to a System Center 2012 – Data Protection Manager (DPM) protection group set. A DPM protection group is a collection of protection groups that you collocate on the same tape.

Parameters

-Add<ProtectionGroup>

Specifies a protection group. The cmdlet adds this protection group to the protection group set.

-AllowDifferentRetentionPeriods

Indicates that protection groups with different retention periods can be part of the same protection group set.

-ExpiryToleranceUnit<PGSet+TimeUnit>

Specifies the measurement unit for expiry tolerance. Valid values are:

-- Day
-- Week
-- Month
-- Year

-ExpiryToleranceValue<UInt32>

Specifies the maximum length of time for which an expired recovery point remains on a tape before DPM marks the tape as expired.

-Name<String>

Specifies a new name for the protection group set.

-PGSet<PGSet>

Specifies a protection group set that this cmdlet updates. To obtain a protection group set object, use the Get-DPMPGSet cmdlet.

-Remove<ProtectionGroup>

Specifies a protection group. The cmdlet removes this protection group from the protection group set.

-WritePeriodUnit<PGSet+TimeUnit>

Specifies the measurement unit for the write period. Valid values are:

-- Day
-- Week
-- Month
-- Year

-WritePeriodValue<UInt32>

Specifies the length of time for which a tape is available for writing new backups. DPM marks the tape as Offsite Ready after this interval.

-Confirm

Prompts you for confirmation before running the cmdlet.

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

Outputs

The output type is the type of the objects that the cmdlet emits.

Examples

Example 1: Update write period and expiry tolerance

This example updates the first protection group set from protection group sets on the on the server DPMServer07 with values for write period and expiry tolerance.

The first command uses the Get-DPMPGSet cmdlet to get the protection group sets for the specified server and stores them in the $PGSet variable.

The second command specifies the first member of $PGSet by using standard array notation. The command updates values for write period and expiry tolerance.

PS C:\> $PGSet = Get-DPMPGSet -DPMServerName "DPMServer07"
PS C:\> Update-DPMPGSet -PGSet $PGSet[0] -Name "PGSset3" -WritePeriodUnit day -WritePeriodValue 60 -ExpiryToleranceUnit Day -ExpiryToleranceValue 10

Example 2: Add a protection group to a protection group set

This example adds a protection group from DPMServer07 to the first protection group set on that DPM server.

The first command uses the Get-DPMPGSet cmdlet to get the protection group sets for the specified server and stores them in the $PGSet variable.

The second command uses the Get-DPMProtectionGroup cmdlet to get a protection group from the specified DPM server that has a name that contains PG1, and then stores it in the $PGroup variable.

The third command specifies the first member of the $PGSet variable by using standard array notation. The command updates that set to contain the protection group stored in $PGroup.

PS C:\> $PGSet = Get-DPMPGSet -DPMServerName "DPMServer07"
PS C:\> $PGroup = Get-DPMProtectionGroup -DPMServerName "DPMServer07" | where {($_.friendlyname) -match "PG1" }
PS C:\> Update-DPMPGSet -PGSet $PGSet[0] -Add $PGroup

Example 3: Remove a protection group from a protection group set

This example removes the first protection group set from the list of protection group sets on the DPM server TestingServer.

The first command uses the Get-DPMPGSet cmdlet to get the protection group sets for the specified server and stores them in the $PGSet variable.

The second command uses the Get-DPMProtectionGroup cmdlet to get a protection group from the specified DPM server that has a name that contains PG1, and then stores it in the $PGroup variable.

The third command specifies the first member of $PGSet by using standard array notation. The command updates that set to no longer contain the protection group stored in $PGroup.

PS C:\> $PGSet = Get-DPMPGSet -DPMServerName "DPMServer07"
PS C:\> $PGroup = Get-DPMProtectionGroup -DPMServerName "DPMServer07" | where { ($_.friendlyname) -match "PG1" }
PS C:\> Update-DPMPGSet -PGSet $PGSet[0] -Remove $PGroup
