Emulate recalculate button with powershell

[acasanovanex]

Hello,

Is there a way to emulate the recalculate button functionality (when editing/creating a job) from a powershell script?

I've already explored the Veeam.Backup.Core.CBackupJob and Veeam.Backup.Core.CObjectInJob objects but I was unable to find a method to achieve such thing.

I know I can get the VM size from vCenter but I would rather do it through Veeam...

Thanks.
Ángel

Hi Angel,

Not sure it is possible to emulate recalculate button with Veeam PowerShell commands (at least I haven't found a quick way to do that), so I would suggest using VMware's PowerCLI to calculate source VM data size.

Thanks!

Thanks for your answer Vitaly.

I've been looking for a way to do this. Does anyone have a way to generate the size of the backup job via script?

We mave multiple backup jobs pointing to a single VMware cluster that has hundreds of VMs on it. We do this to meet the recommended backup size limits for backup jobs as recommended by Veeam. We want to get this value via script so we can write a report displaying the size of all the VMs in the backup job. This is used to allocate new machines in vCenter to the smallest sized backup job and as a notification for us to create a new backup job if the size limites have been reached. In vCenter VMs are placed into Resource Pools which are containers that are targeted in Veeam backup jobs. This way only the action of placing the machine into a VMware container is required to make sure its getting backed up. But the report really should come from the Veeam APIs as that is what we are trying to measure against. I found the value in $vbrjob.Info.IncludedSize. But it seems not to even populate unless the "Recalculate" button is pressed in the GUI, a tediously long process with lots of jobs. It was be very nice to get this action to happen automatically or via script.

Thanks!

Try the PS code discussed in this thread to get the info you need > Powershell script to report daily backup sizes

I don't know any way to force the "recalculate" button so that $vbrjob.Info.IncludedSize is updated, however, you should be able to get the equivalent by adding up the size of each Job Object within the job, which you can get from $vbrjob.GetObjectsInJob(). This will return an array of each object in the job, which will have a size available in the ApproxSizeString variable (for container objects it's the estimated used size of all VMs in the container). Unfortunately this value is a string so you have to manipulate it a little bit and add the values of all objects together. Something like the following should work:

Code: Select all

$job = Get-VBRJob -Name "Test Job"
$jobsize = 0
$job.GetObjectsInJob() | ForEach-Object {$jobsize = $jobsize + [decimal]($_.ApproxSizeString -replace " GB$")}

EDIT: I just noticed that this value isn't always updated either, but there is a "TryGetApproxSize()" method that I would think would be used to update an objects size info. I need to see if I can figure that out.

Hello everyone,

I am using power shell to create a backup job that specifies a VMWare Resource Pool instead of individual VMs. I noticed that when I specify the resource pool on the "Add-VBRViBackupJob" commandlet. The size of the resource pool is not shown on the column nor Total Size field on the "Virtual Machines" step of the wizard. However, if I press the "recalculate" button it pulls the correct size

Any tips how to achieve this thru the Veem backup PS

[veremin]

To be honest, I can’t see any way of how this can be done using Veeam PowerShell Snap-in only. I can’t get it work neither by using ApproxSizeString nor by TryGetApproxSize() method (probably, some more qualified guy might correct me).

So, from my perspective, apart from pushing “recalculate” button this information can be only obtained from hypervisor directly via PowerCLI.

Hope this helps.
Thanks.

Thanks everyone fro the quick answer. The script and post are very useful. One last question If I want the GUI to show the size after my Job is created is then the "Recalculate" push button the only option ?

[tsightler]

I've also been unable to get this to work with previous attempts so for now it looks like the button press is the only option.

One last question If I want the GUI to show the size after my Job is created is then the "Recalculate" push button the only option ?

Yep, it seems to be the only option.

Moreover, after having done it, you’ll be able to get the right size of the job objects even through PS, using the following example:

Code: Select all

asnp VeeamPSSnapin
$Job = Get-VBRJob -name "Name of your Job” 
$Job.info.IncludedSize 

Hope this helps.
Thanks.

Thanks a lot Vladimir

[veremin]

Not a problem. Should any additional help be needed, let’s know.

Thanks.

V - is this supposed to refresh the backup jobs ?

Code: Select all

asnp VeeamPSSnapin
$Job = Get-VBRJob -name "Name of your Job” 
$Job.info.IncludedSize

I am using v8 ....2030 and it is not refreshing the backup jobs..
We are migrating from one vcenter server to a new one (changing versions as well.)
So refreshing the backup list would be a great thing to do...

[veremin]

Nope, as mentioned above, the provided command takes size as is. So, manual "Recalculation" is still needed. Once you run it, the given command will show the proper value. Thanks.

Hello,

is it possible to get the estimated "Total size" value on the backup job wizard (under the "Recalculate"-button) per Powershell?
If yes, with which command?

I need this information for some costs billing / accounting actions. I don't want to use the real size, because I need such information before the first backup starts.


Thank you,

Emanuel

Check the thread your post has been merged into. Some useful examples are provided above. Thanks.

[billcouper]

None of the above examples are useful, as everyone agrees that this is an impossible task using powershell.
According to this thread, the only way is to manually click the 'Recalculate' button in the GUI.

I too, would like a powershell method of doing this. Is there any change in v9.5 that provides the ability to do this simple task using powershell?
Manually clicking recalculate on dozens of jobs is mildly amusing, but only the first time.

[veremin]

Unfortunately, no changes in terms of recalculate cmdlet. Thanks.

[evilaedmin]

Any updates re: Update 4?

[veremin]

No, Update 4 does not have a cmdlet for that. Thanks!

[evilaedmin]

Just curious, is this at all on the road map?

[veremin]

It's tracked, yes, but it is not something we will implement in short-term future. Thanks!

Hi,

Could you please add option to recalculate the total size of VMs to backup via PowerShell?
We have preconfigured jobs that are based on the VMware tags and created a script that checks the size of the jobs. If size is zero it disables the job so there wouldn't be any errors or warnings. When you tag a VM for job that's disabled, as it didn't have any VMs to backup, you need to edit the job via GUI and press recalculate button so it would update the size and script would re-enable the job.

The only information that I could find on the Internet is this forum with latest reply in 2019. powershell-f26/emulate-recalculate-butt ... 14178.html

I logged a Case #06201324 and was advised that at this stage there is no command to do this.

Thanks,
Max
