Description

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

Examples

Example 1: Update 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

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.

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

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

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.

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

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

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.
