Start-VBRZip in Veeam Backup Free Edition

Darkyputz · Post by **Darkyputz** » Oct 04, 2016 3:28 pm this post

Hello...

I am running into an issue with password protected shares right now and thought i got around it by adding the following net use statement to the script.
But all i get is a functionality that is able to connect to the share and create folders successfully...but when it comes to Start-VBRZip...it seems to fail...no reaction on the vSphere(normally is see changing this and that in the log)
Without the net use part i get access denied on the network share...
Can someone see the culprit right away that i don't see?!

Thx

Code: Select all

...
$unc_user = 'user',
$unc_password = 'password',
...

net use $bk_repository $unc_password /USER:$unc_user 
try  
{
    foreach($vm in $result)
    {
    Write-Host "Backing up vm: $vm"
    $vm_tobackup = Find-VBRViEntity -Name $vm -server (Get-VBRServer -name $vsphere_host)
                        $path_tobackup = $bk_repository + "\" + $vm + "a"
                        Write-Host "Path to backup: $path_tobackup"
    #BACKUP VM
            if(!(Test-Path -Path $path_tobackup ))
            {
                New-Item -ItemType directory -Path $path_tobackup
            }
    $bk_result = Start-VBRZip -Folder $path_tobackup -Entity $vm_tobackup -Compression $bk_compression -autodelete $bk_autodelete
    $aBkResult = $aBkResult + $bk_result
    }

    ###Create the mail report
    $mail_text = $mail_text + "<tr align='center'><b><td>JOB NAME</td><td>START TIME</td><td>END TIME</td><td>DURATION (min.)</td><td>RESULT</td></b></tr>"
    foreach($result in $aBkResult)

    $result_color = ""

Hi Jan,

Can you please try a workaround suggested in this topic? See the answers provided above.

Thanks!

Will try...was just somewhat hard to find my subject...smile...
Thx for the idea so far

Hello again...not sure if i got the suggested solution right...
Can you explain what they did to get it working?!

Ok...got that...but "Veeam" account ?!?!
Which user is veeam using?! Will not be Veeam as user name or do i miss something here?!
How can i authenticate the Veeam service?!

Post by **veremin** » Oct 12, 2016 1:09 pm this post

Account under which corresponding backup service is executed. Thanks.

LOVE YOU GUYS!!!!

Works...so easy that it is embarrassing that i was not seeing it my own...

THX!

No worries. So far this has been number one request we got in regarding Start-VBRZip cmdlet enhancements. We're planning to add -NetworkCredentials parameter to the said cmdlet down the road in order to make our customers' lives easier. Thanks.

Hello,

unfortunately I seem to be to stupid to get it working with my Synology NAS. I want to Backup directly with the script to a NAS Share called "Backup":

\\10.10.10.5\Backup\

The Backup&Replication Software is installed on a Windows 10 Machine in a Non-Domain (WORKGROUP) where I execute the script in Powershell with admin rights testwise.

The Backup fails due to an access error (username or password is false).

I assume I have to solve these issues according to posts above:

1) Veeam account read/write permissions on the given share
2) Computer account read/write permissions on the given share

I do not know what is meant by that? What is the "Veeam account" and how do I give it permission to the share?
Do I have to map the UNC on the PC in advance?

I created a user on the NAS with the same name of the PC-User logged in (e.g. Tom) and gave the user the same password than on the PC.
This user has the right to access the Backup share but this does not work??

Can someone be so kind to explain this more in depth?

Highly appreciated

tomtom · Nov 19, 2016 12:58 pm

OK, I finally solved the problem myself. If anyone else having this problem, here is the solution:

Change the Veeam services on the backup machine (e.g. PC) that they are not running under "local system account" but under your specific account that has corresponding rights to access (read/write) the NAS. The local system account has no rights to access network destinations.

Post by **veremin** » Nov 20, 2016 2:23 pm this post

Correct, by Veeam account we refer to account under which Veeam-specific services are running. Sometimes changing that account does not solve the issue, and additional permissions must be granted to VB&R computer account.

Glad to hear that you're up and running now.

Thanks.

->v.Eremin

Thankfully your script makes it easy for newcomers to successfully perform backups ;D Thank you for that!

Can you tell me one more thing in respect of he $Retention date in your script? Is the date stored in the .vbk file or is just processed by B&R software with the next backup?
I ask because I backup the .vbk to a CIFS share and afterwards the same .vbk will be copied by the NAS to an external HDD (rotation) via USB.
So e.g. when I set "Retention" to "Tomorrow" in B&R I assume the .vbk will be deleted on the next day on the CIFS share after creation.
But does this also mean that this particular backup cannot be restored later e.g. after a week when I try to restore a copy of the .vbk stored on a external HDD?

The backup file itself does not have any time bomb or something. It's backup software that issues remove command when time comes (not with the next backup). Thanks.

Ok, thank you. Time Bomb was the term in short I was looking for ;D

Hi,

have a small question with free version 9.5 and powershell script.

I use the orginal powershell script, but if i input two vms to backup script, first vm gets backuped, but second one gets this error:

Start-VBRZip : Veeam Backup Free Edition does not support of multiple VMs backup. Specify a single VM, or install a
paid product license.

I know about free version can only backup one vm at time.
But the script is working vm after vm.
Any idea?

Big thanks
Bye

Post by **Vitaliy S.** » Nov 30, 2016 1:46 pm this post

You need to invoke Start-VBRZip twice, if you want to back up two or more VMs in the job.

sscheller · Post by **sscheller** » Nov 30, 2016 1:52 pm this post

Could you please explain this?

Where there i a comment inside the script to define multible vms ?

# Names of VMs to backup separated by comma (Mandatory). For instance, $VMNames = “VM1”,”VM2”

Post by **veremin** » Nov 30, 2016 2:26 pm this post

Can you provide the version of the script you're using? Only if you try to backup several VMs simultaneously, should you get the said error. Thanks.

sscheller · Post by **sscheller** » Nov 30, 2016 2:36 pm this post

Hi, i take your script from 3/24/2015 (update)
But i also tried some other scripts.
If i start the script over powershell and the first vm finishs, the error is coming.

Post by **veremin** » Nov 30, 2016 2:40 pm this post

Let me try to run my code against version 9.5 and see whether the said error shows up. Thanks.

Post by **veremin** » Nov 30, 2016 3:06 pm this post

Checked the script with 9.5 free version, everything has worked as expected. Most likely, you've modified the script somehow, so that it tries to pass several VMs to -Entity parameter of Start-VBRZip commandlet. Thus, the error. Thanks.

ischneider · Post by **ischneider** » Jan 04, 2017 1:02 pm this post

Veeam Backup & Replication 9.5
Verision .5.0.711
License Free Edition

When using power shell command Start-VBRZip resulting backup files are always created using local administrator's account instead of the account used to run the script / command.
Thus resulting in access denied error for the NAS file system which only knows about domain users.

Has anyone encountered this issue before or knows a solution?

Thanks and Regards,

Ingo

Post by **veremin** » Jan 04, 2017 1:14 pm this post

I'd say this is an expected behaviour. Backups are always created with the use of account specified as backup service account (under which VB&R related services are running). The account used to run script doesn't play crucial role here.

Thanks.

ischneider · Post by **ischneider** » Jan 04, 2017 1:20 pm this post

Well, using Veeam Backup & Replication Console, the backup files will be created for the user starting the console....
That's why I was expecting similar result using command line tool.....

And btw. the Veeam Backup Service is running by a domain user which would be fine to access the NAS....
Which Veeam service would need to be changed to use the expected domain user having proper access rights for the NAS?

Post by **veremin** » Jan 04, 2017 1:31 pm this post

Veeam Backup Service one. Thanks.

Hello,

this is my first post about this product I think is really powerful. Considering the various possibilities I stumbled into powershell script released by Vlad Eremin and I was wandering if someone in this forum has used or is using it

I am going to try it very soon but I am interested in paticular in the encryption feature

Code: Select all

...
$EnableEncryption = $False
...
$EncryptionKey = ""
...

and if someone has tried to use some different method to encrypt the backup files in such a way that non imply put clear-text passwords in the code

thank you!

Post by **veremin** » Jan 10, 2017 9:48 am this post

Have you seen the corresponding blog post where I elaborated on encryption portion of the script? Thanks.

solidus · Jan 10, 2017 1:52 pm

Hello Vlad, thank you so much for the script that you created, its very useful!

Yes, I was just talking about that, in the encryption portion its demonstrated how to use a password via Read-Host and ConvertFrom-SecureString from a file. In the first case its not so useful to automate in a task scheduler job. In the second case it still requires a txt file containing an encrypted password but it is still easy decriptable

A good way would be that the script gets the credentials from windows password vault... I remember a discussion about that on stackoverflow
http://stackoverflow.com/questions/2910 ... powershell

Ill try to implement it using the windows credential manager APIs with the CredMan.ps1 script
https://gallery.technet.microsoft.com/s ... s-d44c3cde

I was asking if someone has already done that, I searched in the forum but with no results...

Thank you again!

Post by **veremin** » Jan 10, 2017 1:59 pm this post

Personally I haven't tried that (just covered the very basic scenario), and doubt that anyone else has. So, I'd be interested to hear the results of your findings. Thanks.
