Backup size per vm

[karsten123]

Hi,

is it possible to get the backup size per vm?
I allready have the per job sizes.

VBR is 11a; backup repository is set to per-vm chain.

Thank you in advance.

Hi Karsten,

If you want to get backup size per each vm contained in a backup, you need to obtain storages and their sizes.
Example:

Code: Select all

$backup = Get-VBRBackup -Name 'Backup Job 1'
$rps = Get-VBRRestorePoint -Backup $backup
$totalRps = @()
foreach ($rp in $rps) {
    $storage = $rp.FindStorage()
    $sizeRounded = [Math]::Round($storage.Stats.BackupSize/1GB, 2)
    $totalRps += $rp | select Name, @{n='BackupSizeGB';e={$sizeRounded}}

}
$totalRps

If want to get backup size per every vm chain, the concept is the same, but you also need to do some simple calculations to present the sum of backup sizes for each unique backup object.
Example:

Code: Select all

$backup = Get-VBRBackup -Name 'Backup Job 1'
$rps = Get-VBRRestorePoint -Backup $backup
$objects = $backup.GetObjects()
$objectChains = @()

foreach ($object in $objects) {
    $objectRps = $rps | where {$_.ObjectId -eq $object.Id}
    $backupSize = 0
    foreach ($objectRp in $objectRps) {
    $storage = $objectRp.FindStorage()
    $sizeRounded = [Math]::Round($storage.Stats.BackupSize/1GB, 2)
    $backupSize += $sizeRounded
    }
    $objectChains += $object | select DisplayName, @{n='BackupSizeGB';e={$backupSize}}

}

$objectChains

Thanks,

Hi Oleg,

thank you very much. Wow. That is exactly it.

Have a nice week.

This works amazing.

Now, how would i do this for All jobs? instead of 'Backup Job 1' I'd love all the jobs to get checked.

I'm assuming run the whole script for each job in jobs or something, but i am not a powershell expert

Hi @vmtech123,

Few ways but laziest way is just get all Backups and then use a foreach loop and nest the above code into the loop. For example:

Code: Select all

$backups = Get-VBRBackup
$objectChains = @()

foreach($b in $backups){
	$rps = Get-VBRRestorePoint -Backup $b
	$objects = $b.GetObjects()

	foreach ($object in $objects) {
		$objectRps = $rps | where {$_.ObjectId -eq $object.Id}
		$backupSize = 0
		foreach ($objectRp in $objectRps) {
		$storage = $objectRp.FindStorage()
		$sizeRounded = [Math]::Round($storage.Stats.BackupSize/1GB, 2)
		$backupSize += $sizeRounded
		}
		$objectChains += $object | select DisplayName, @{n='BackupSizeGB';e={$backupSize}}

	}
}
$objectChains

Notice a few things:

1. Move the array initialization for $objectChains outside of the loop, otherwise it will initialize a new array on every loop (and erase the old one )
2. For any point calling the CBackupObject ($backups in Oleg's original code), we rename it to the variable $b chosen for the loop

Thanks so much. I appreciate the help and the fact you explained WHY I think i was on the right track but this makes sense.. Awesome

Always welcome! Good luck with scripting

And I'm glad you like the explanations; they come from the pain I went through learning this stuff, so learn from my pain
