Hello,

I am wondering why there are two cmdlets Remove-VBRBackup and Remove-VBRRestorePoint when both do exactly the same thing; deleting the entire backup chain.
Is this intended or is the Remove-VBRRestorePoint misbehaving?

We have Reverse Backup chain with 3 Restore points.

Code: Select all

Get-VBRRestorePoint -backup backupjob1 | Sort-Object creationtime -Descending
show the following:
VM Name Creation Time Type Failoved
----------- ---------------- ------ ----------
VM1 03.09.2014 15:00:41 Full
VM1 03.09.2014 14:12:19 Rollback
VM1 03.09.2014 12:56:21 Rollback
We want to delete point 03.09.2014 14:12:19 so we did the following:

Code: Select all

$restorepoint_obj=Get-VBRRestorePoint -backup testjob2 | Sort-Object creationtime -Descending | Where {$_.type -eq "Rollback"} | Select -First 1
resulting in $restorepointobject holding the following:
VM Name Creation Time Type Failoved
----------- ---------------- ------ ----------
VM1 03.09.2014 14:12:19 Rollback
Now we go:

Code: Select all

Remove-VBRRestorePoint -Oib $restorepointobject
The Result is that the complete Backup of backupjob1 is deleted. If we wanted to get such an result we simply could have used:

Code: Select all

Get-VBRBackup -Name backupjob1 | Remove-VBRBackup
.

So are we missing something on Remove-VBRRestorePoint?

Restore point deletion should be managed by retention settings. If you try to remove a restore point either via GUI (Remove from disk) or via PS (Remove-VBRRestorePoint/Backup) the whole chain will be deleted. Thanks.

Than maybe renaming the cmdlet would be a nice thing as the name implicates an absolutely other behaviour (remove just restorepoint not complete chain) or remove it entirely as there allready is Remove-VBRBackup to remove the entire backup chain.
Also the description of Remove-VBRRestorePoint tells otherwise especially in Example 1:
This command removes the increment restore points from all backups with names containing "Fileserver".
This sentence says that only the increment restore points get delete but infact the fulls are also deleted because the whole chain get trashed.
So there is some inconsistency in information and naming that should be corrected.

Can you also tell me how many VMs are present inside the given job? Is it just one VM1? Thanks.

In this particular job its 2 VMs.
From only one of them we wanted to delete all rollback points and keep only the full backup points.

Not sure what might be wrong in your case, but I've checked Remove-VBRRestorePoint commandlet briefly and haven't been able to confirm the described behavior. In my case, only restore points of particular VM have been removed. However, I have a forward incremental mode, not reversed incremental one. Later on, I will try to test it with reversed incremental mode, as well, and post my findings. Thanks.

Hmm, Ok I will check with a Job of normal incremental backup on my site to see if we get behaviour as expected on this.

Did a test with normal incremental backup

Code: Select all

Code: Select all

VM Name Creation Time Type Failoved
------- ------------- ---- --------
test20 05.09.2014 12:47:21 Increment

Code: Select all

PS> $restorepoint_obj=Get-VBRRestorePoint -backup testjob1 -name test20 | Sort-Object creationtime | Where {$_.type -eq "Increment"} | Select -First 1
PS> echo $restorepoint_obj
VM Name Creation Time Type Failoved
------- ------------- ---- --------
test20 05.09.2014 12:47:21 Increment

Code: Select all

PS> Remove-VBRRestorePoint -Oib $restorepoint_obj
Bestätigung

test22 05.09.2014 12:47:23 Increment
test22 05.09.2014 12:27:59 Full
So result is not only increment of Vm test20 gets deleted but fulls also.
Why is this? Fulls, regardless of wether active or synthetic, could stand on their own and don't rely on increments whatsoever. So why did the fulls get deleted, especially when only one object of an increment gets passed over?
The chain of test22 still exists, but the outcome regarding test20 is still not what one would expect.

Retention was set to hold 5 restorepoints. Maybe it trashes the fulls too because deleting the increments reduce retention to only 2 points violating the policy?

Results in removing all restorepoints of test22.

So how the object is passed to Remove-VBRRestorePoint did not matter.

Both GUI and PS rely on the same mechanism. So, if you try to delete individual restore point of particular VM, all restore points related to the VM will be deleted.

As to the difference between Remove-VBRRestorePoint and Remove-VBRBackup, using the former you can remove restore points of particular VM(s) out of existing chain, while with the latter one the whole backup will be deleted.

Thanks.

Hello,

A little update on this.
On get-vbrrestorepoint you can call an method called delete, you can call it to delete a specific restore point :

PS C:\Users\Yoann> Get-VBRRestorePoint

VM Name Creation Time Type
------- ------------- ----
Finnix 10/12/2015 14:14:13 Full
Finnix 10/12/2015 14:41:19 Full
Finnix 10/12/2015 15:05:39 Increment
Finnix 10/12/2015 15:18:55 Increment
Finnix 10/12/2015 17:27:56 Full


Select only the increment :

PS C:\Users\Yoann> $RP=Get-VBRRestorePoint -Name Finnix | Where {$_.type -eq "Increment"}
PS C:\Users\Yoann> $RP

VM Name Creation Time Type
------- ------------- ----
Finnix 10/12/2015 15:05:39 Increment
Finnix 10/12/2015 15:18:55 Increment


and the increment are gone :

PS C:\Users\Yoann> $rp.delete(1)
PS C:\Users\Yoann> Get-VBRRestorePoint

VM Name Creation Time Type
------- ------------- ----
Finnix 10/12/2015 14:14:13 Full
Finnix 10/12/2015 14:41:19 Full
Finnix 10/12/2015 17:27:56 Full


At the next run of the job, there will be gone on the GUI and on the backup repository as well.

Please note that, after a review with support, this method is not supported by Veeam as it doesn't remove SQL entries on all table.
This method can also be deleted in further version

Use it in emergency or with support help only
