How to repeat failed tape backup attempt in DPM 2007?

Question

How do you repeat a scheduled backup of a protection group if the first backup attempt failed (e.g. if there were no tapes in the library, or if there was an intermittent failure in the library or drive).

I know that you can force a backup of single protected element in the console by selecting "Create Recovery Point - Tape" in the context menu, but how do you force a tape backup of a whole protection group?

_{DISCLAIMER!! These are cleaned up versions of what I actually use, I have not had a need to test these cleaned versions, so they probably contain an error or two. My apologies! Please comment/edit/anything if do find a mistake so others don't have to fix it again.}

If you still have the error in Monitoring -> Alerts, you can right click it an select Resume Backups.

If you want to create a new backup (what's currently on the protected server)
Open the DPM Shell and paste this script:

param([string] $dpmname, [string] $pgname)

if(!$dpmname) {
    $dpmname = Read-Host "DPM server"
}
if(!$pgname) {
 $pgname =  Read-Host "Protection Group Friendly Name"
}
Write-Output "Creating Tape Recovery Point"
trap{"Error in execution... $_";break}
&{
    Write-Output "Getting protection group $pgname in $dpmname..."
    $clipg = Get-ProtectionGroup $dpmname | where { $_.FriendlyName -eq $pgname}
    if($clipg -eq $abc) {
        Throw "No PG found"
    }
    Write-Output "Getting DS from PG $pgname..."
    $backupds = @(Get-Datasource $clipg)
    foreach ($ds in $backupds) {
        Write-Output "Creating Recovery point for $ds..."
        $j = New-RecoveryPoint -Datasource $ds -Tape -ProtectionType LongTerm
        $jobtype = $j.jobtype
        Write-Output "$jobtype Job has been triggerred..."
    }
}

It will ask for the name of the Server and Protection Group to be backed up.

If you want to copy a disk backup to tape media (for the whole protection group)
Open the DPM Shell and paste this script:

param([string] $dpmserver, [string] $pgname, [datetime] $rpdt, [int] $tapeoption)
$searchminutes = 10
$libraryindex = 0
if(!$dpmserver) {
    $dpmserver = Read-Host "DPM server"
}
if(!$pgname) {
    $pgname =  Read-Host "Protection Group Friendly Name"
}
if(!$rpdt) {
    $rpdt = Read-Host "Time of existing Recovery Point"
    if (($rpdt -as [DateTime]) -ne $null) {
        $rpdt = [DateTime]::Parse($rpdt)
    } else {
        Write-Host 'You did not enter a valid date/time!'
    }
}
$rpdt.AddMinutes($serachminutes / 2)
if(!$tapeoption) {
    $tapeoption = Read-Host "Tape Option: 0 = Compress, 1 = Encrypt, 2 = Neither"
}
Write-Host "Creating $backupoption Recovery Point"
trap{"Error in execution... $_";break}
&{
    Write-Host "-Getting protection group $pgname in $dpmserver..."
    $clipg = Get-ProtectionGroup $dpmserver | where { $_.FriendlyName -eq $pgname}
    if(!$clipg) {
        Throw "No PG found!"
    }
    Write-Host "-Getting libraries on $dpmserver..."
    $libraries = @(Get-DPMLibrary -DPMServerName $dpmserver)
    if(!$libraries) {
        Throw "No Tape Drive/Library found!"
    }
    Write-Output "--Getting Data Sources from Protection Group $pgname..."
    $backupds = @(Get-Datasource $clipg)
    foreach ($ds in $backupds) {
        Write-Host -NoNewline "---$ds... "
        $rps = @(Get-RecoveryPoint -Datasource $ds) | Where { (New-TimeSpan -Start $_.RepresentedPointInTime -End $rpdt).TotalMinutes -lt $searchminutes }
        Write-Host -NoNewline "RPs Found... "
        foreach ($rp in $rps) {
            Write-Host -NoNewLine "Creating Job... "
            $j = Copy-DPMTapeData -RecoveryPoint $rp -SourceLibrary $libraries[$libraryindex] -TapeLabel "asdf" -TapeOption $tapeoption -TargetLibrary $libraries[$libraryindex]
            Write-Host "Job: $j.status"
        }
    }
}

Note: If you know what you're doing, the basic structure of the above script is:

$libs = @(Get-DPMLibrary -DPMServerName $dpmname)
$pg = @(Get-ProtectionGroup -DPMServerName @dpmname)
$ds = @(Get-Datasouce -ProtectionGroup $pg[n])
$rp = @(GetRecoverPoint -Datasource $ds[n])
Copy-DPMTapeData -RecoveryPoint $pr[n] -SourceLibrary $libs[n] -TapeLabel "Whatever" -TapeOption $x $TargetLibrary $libs[n]
