Powershell - Rotated Drives - Delete content

Post by SuperYosh »

Hi !
I'm new to this board, but I read a lot allready, thanks !

I have an issue with my VBR10, HyperV cluster, and backupcopy to external drives ...
I need to make a backup copy job every week to several USB HDD (4 to be precise) but these drives just have enough room for one backup copy ... I can't have Increments, and a synthetic full done BEFORE deleting older backups for retention. That's because of budget, I can't move this cursor ...

So, I am working on a script to automatically delete everything on these USB Hardrive as soon as the task begins, by using "script" option.

Here is my script :

Code: Select all

powershell -command "&{ Add-PSSnapin VeeamPSSnapin ; Get-VBRBackup -Name *EXT | Remove-VBRBackup -FromDisk -Confirm:$false }"
As you can see, this script SHOULD work fine, and it is if use it from a command line, BUT it didn't work when launch from backup tasks.
Can anyone help me please ?

Hi Johan,

Are you using this command directly as a pre-job script or wrap it in a bat file and then select it from pre-job scripts browser?
Have you tried just saving the commands you need to invoke as a ps1 file and select it as pre-job script?

Thanks,
Oleg

Hi Oleg,
The job is used in a .bat called from the pre-job script window.
As you asked me, did you mean that pre-job script can launch .ps1 files ?

Yep, that's exactly what I meant. Could be easier to just invoke ps script directly. Thanks!

I would suggest setting up your script to run with a transcript to a local file, so you can see exactly what is happening/failing.

Hi,

First of all, make sure VBR finds powershell script and successful execution of pre-job script is logged to a backup session (no exit code 1).
If all is fine but the script itself doesn't seem to work, proceed with some simple logging to a file:

Code: Select all

asnp VeeamPSSnapin
Get-VBRBackup -Name *EXT | Remove-VBRBackup -FromDisk -Confirm:$false *> C:\job.log
Make sure to use precisely *> to redirect all streams, including errors, to one file.
Then, check the output in C:\job.log

Thanks
Oleg

Hi,

That was that simple ... *facepalm*
Sorry, I begin with Powershell and VBR. I'm going to try that and come back to give you the result. Thanks !

Got the result, and I dont' understand it :

Code: Select all

CreationTime : 29/04/2021 16:25:16
EndTime      : 29/04/2021 16:25:22
JobId        : 68541dd7-fa52-4a05-9a29-ff2f03d53682
Result       : Failed
State        : Stopped
Id           : 0c071acc-e5bd-4495-9ddb-9c8552d51f57
Can you help me ?

// edit :
When launch from PowerShell manually it works : "Removing backup / Please Wait ..." etc.

If it was the last backup you attempted to delete, please post the output from the following script:

Code: Select all

$jobType = [Veeam.Backup.Model.EDbJobType]::DeleteBackup
$deletionSession = [Veeam.Backup.Core.CBaseSession]::FindLastByJobType($jobType)
$log = $deletionSession.Logger.GetLog()
$log.UpdatedRecords | select Title, Status 
This script dives into the session logs and outputs some relevant info about it.

Thanks,
Oleg

It actually makes sense. I think, instead you could create a task in Windows Task Scheduler, which would sequentially invoke backup deletion script and then start backup copy job. This task would subscribe to an event of usb drive discovery in event logger, so that task scheduler would trigger it on each event occurrence. Thanks!

It makes sense ... but don't help me to duplicate this behavior on multiple sites :(

Is it possible to have a task/script that can start the task, BUT wait for the files to be deleted before beginning the BackupCopy ?

I allready have I Windows Task to make sure the External BCJ will run on saturday/sunday ONLY. And stops on monday early morning so I can have mail with 100% jobs done at the benning of a new week.

By default, Remove-VBRBackup will wait for the backup deletion before returning anything unless you specify -RunAsync parameter.
So, just make sure to run the following sequence:

Code: Select all

asnp VeeamPSSnapin
Get-VBRBackup -Name *EXT | Remove-VBRBackup -FromDisk -Confirm:$false
$job = Get-VBRJob -Name 'Backup Copy Job'
Start-VBRJob -Job $job
Thanks,
Oleg

Another option is to just delete the files on the drive (BATCH or Powershell) and set the option on the repository "rotated drives" so it doesn't freak out if the files are deleted.

Oleg, your sequence works just fine !
But ... I lost visibility on the VBR GUI console for this job : I only have "Running pre-job script" in the VBR window if I want to monitor it.

If you have an alternative, or a way to "show" what's going on in real time ?
Thanks :)

@ITP-Stan that's what we are tyring to FROM the VBR Job. I need to automatize this, and deploy this on multiple site with equivalent configurations. So your BATCH/POWERSHELL only idea is sadly not enough for my needs. But thanks :)

Since you invoke this script from Task Scheduler, you can just stream execution logs to a file as I showed above. Thanks!
