Hello,

Can anyone shed some light on why I get this error?

Start-VBRZip : A parameter cannot be found that matches parameter name 'AutoDelete'.
At C:\PowerShell Scripts\VeeamZIPaldc1.ps1:86 char:132
+ ... leQuiescence) -AutoDelete $Retention
+ ~~~~~~~~~~~

If I take out "autodelete" it works.

Hi, Steve,

That's the main reason why the referenced script doesn't seem to work - either PS or backup server version is a bit out-dated one.

Anyway, glad to hear that now everything is up and running.

Thanks.

Will this work with PowerShell version 4? That's the only thing that's different. I've applied Update 2. This is the first error being reported

Code: Select all

Asnp : No snap-ins have been registered for Windows PowerShell version 4.

It should. The most frequent solution that I've seen so far for similar issue is to re-install Update 2b along with PS snap-in. Thanks.

I'll try reinstalling the update. Just waiting for a backup to finish :) PS Snap-in is included in Update 2b, right?

Support ID 00999684 it's an old one, but it won't let me post without an ID. Stupid

Let's wait till support team analyze the corresponding logs, then. They'll be able to find out the root cause of the experienced behaviour. Thanks.

Please forgive my excessive noob-ness. I had this running a treat for a while, customer was loving it, I was loving it. It appears that the trial license that it made me install has expired and I am unable to get a backup running again.

Error message is:

Code: Select all

PS C:\Dynamic_Scripts> .\Veeam-SAS-DC.ps1
Start-VBRZip : Your trial license has expired.
To continue using the product, please purchase a full license.
To purchase a full license, please submit a request at http://www.veeam.com/sales
A sales representative will contact you shortly after your request has been received.

Is there a way to remove this, revert back to the free edition (I have set the UI to the Free Functionality only not the Full functionality) but so far am unable to get rid of this trial license restriction.
Sorry if this post hurts your head with its stupidity but we've been trying to sort this for 3 weeks.
Thanks

Hmm, I don't think that I've tested the script against deployment that has trial license expired.

If possible, I'd recommend re-installing backup server from a scratch and not specifying any license during installation (that should make installation free edition from the beginning).

Thanks.

Hello, I'm new to Veeam and wanted to try out the PowerShell script being talked about here. Unfortunately, it looks like the download links are all dead, along with most of the screen-shots in the shown in the blog post. Does anyone happen to have a copy of the script on hand?

Sorry for a late reply. I must have missed your post.

Anyway, the blog post as well as links it contains seems to be good. They even have been updated recently to address few previously existed inconsistencies. So, kindly check them, if you haven't done it already.

Hi there,

Hope you can help with this - apologies if it's something that's already been discussed.

I am trying to run the hyper-v script as a scheduled task. Veeam v8 is installed on a Server2012 instance, with the Hyper V role installed. Powershell v3.

The script returns the following output when run:

Code: Select all

@TC1927
I originally had the same issue with $Server coming up null. The only way I could get it working was by setting $HostName variable to "LOCALHOST" instead of the actual host name. Might be worth using as a workaround if you're only going to run locally as I am.


I also have my own issue I'm looking for help with:
I have a working script and am jolly about it. Working, that is, as long as I run it manually from PowerShell or from Posh ISE. If I try to run it with Task Scheduler, I get an error about the encryption key. I used Start-Transcript to get the below log when running the script as a SchedTask.

Code: Select all

    + FullyQualifiedErrorId : ParameterArgumentValidationError,Veeam.Backup.PowerShell.Command.AddVBREncryptionKey
I have a text file with password that I reference in the variable for $EncryptionKey. Again, the script works when I run manually but not when run via Task Scheduler. Task setup: Run with local admin-level account, highest priv=yes. Saving the backups locally so no issue there.

Any help is appreciated.

@jbilt2

Thanks for the response - I haven't tried this yet but I'm not sure if it's the answer as the machine running Hyper-V and containing the VMs are separate physical boxes to the one running Veeam.

# Name of vCenter or standalone host VMs to backup reside on (Mandatory)

As I read it, the $Hostname should be the name of your Hyper-V host, which in this case is a remote host rather than local.

As for your issue - have you tried it without encryption (ie encryption = $false) ?

Thanks again

Have you followed instructions provided in the corresponding blog post ("Encryption" section) on how encryption key should be created? Also, if I remember correctly, to make encryption work properly, the account under which secure key has been created should be the same as the account under which the script is executed. Thanks.

Indeed it seems this was my problem. I had created the key with my user but was running the scheduled task as a local user (admin). Recreating the key with the local account allowed the script to run successfully.

But this raises a question/concern about this concept: how does this relate to restoration & decryption of the backup files? Is this user account the only one that will be able to decrypt the data? And a secondary question: if I had used a domain account, would the key be portable to other hosts? Or is the SecureKey not only user-specific, but also machine-specific?

When you try to restore an encrypted backup file, you'll be asked to enter a corresponding password. So, a person knowing a password will be able to restore the data.
And a secondary question: if I had used a domain account, would the key be portable to other hosts? Or is the SecureKey not only user-specific, but also machine-specific?
I think it's a user-specific, but haven't tested that myself. It should be pretty easy to check, though, just copy a corresponding file to a different machine, log on into it, using the same account, try to run a script and see whether you encounter any issue.

Thanks.

What specific issue you get while trying to backup to a specific share via PS? Can you please post a portion of code that fails? Have you tried to map a given share, using New-PSDrive commandlet? Also, does a computer account a script gets executed from has a write permission on the said share? Thanks.

Seems like a $ZIP variable doesn't contain anything, as the result you get the said error. Will the script work if you change target to local disk temporarily?

I was not talking about an user running a script, but rather about computer account that should have write permissions on the share. Otherwise, you'd get Access Denied message (kindly, check the thread your post has been merged into).

What particular error you got?
