Remove deduplication from a volume with powershell

Posted on 17 October 2016 by Albert van Boerum Leave a comment

First check if there is enough diskspace to expand the files to there original size, plus the size of the current deduplication database.

remove the optimization from the volume

Start-DedupJob -Volume D: -Type Unoptimization

1	Start-DedupJob -Volume D: -Type Unoptimization

See the results of the running Job:

Get-Dedup-Job

1	Get-Dedup-Job

Next, clean up the database. For this, deduplication must be turned on.

Start-DedupJob D: -Type GarbageColletion -full

1	Start-DedupJob D: -Type GarbageColletion -full

To turn on deduplication you can explude folders so the deduplication is running but does not do any dedup work.

Set-DedupVolume -Volume D: -ExludeFolder d:\dfs
Enable-DedupVolume -Volume D:

1 2	Set-DedupVolume -Volume D: -ExludeFolder d:\dfs Enable-DedupVolume -Volume D:

When all is done, disable dedup and remove the feature.

Disable-DedupVolume -Volume D:
Remove-WindowsFeature FS-Data-Deduplication

1 2	Disable-DedupVolume -Volume D: Remove-WindowsFeature FS-Data-Deduplication

Counting the number of active backups in Veeam and write this number in an XML file

Posted on 7 March 2016 by Albert van Boerum Leave a comment

This script is used for counting the number of active backups in Veeam and write this number in an XML file for further reference. I use Netcrunch as a monitoring tool and it can proces the content of XML files.

#script for counting the number of running backups in Veeam and
# place this number in a XML file for processing in Netcrunch

#Load the Veeam Powershell commandlets
Add-PSSnapin Veeampssnapin

#get all jobs from Veeam
$jobs= Get-VBRJob

#get running jobs
$runningjobs = $jobs |where{$_.isrunning -eq "True" }

#count running jobs
$countjobsrunning = $runningjobs.count 

#Read the XML file
[xml]$xmlcontent = get-content c:\scripts\runningbackups.xml

#Adjust and save the XML file
$xmlcontent.ncopenmon.counters.counter.'#text' = "$countjobsrunning"
$xmlcontent.Save("c:\scripts\runningbackups.xml")

Working with VHD files and converting them

Posted on 16 November 2015 by Albert van Boerum Leave a comment

To get VHD file type information from hyper-v machines you can use this oneliner. It lists vhd and vhdx files within a folder structure and lists if the disk is Fixed or dynamic in size.

Get-ChildItem *.vhd* -Recurse | get-vhd | select path,vhdtype | ft -AutoSize

1	Get-ChildItem .vhd -Recurse \| get-vhd \| select path,vhdtype \| ft -AutoSize

To convert the files from a fixed format to a dynamic format, use the information from the last command.

Get-ChildItem "*.vhd*" -Recurse | ForEach-Object {Convert-VHD -path $_.fullname -vhdtype Dynamic -DestinationPath ($_.DirectoryName + "\Dyn-" + $_.BaseName + $_.Extension) | Optimize-VHD -path $_.fullname}

1	Get-ChildItem ".vhd" -Recurse \| ForEach-Object {Convert-VHD -path $_.fullname -vhdtype Dynamic -DestinationPath ($_.DirectoryName + "\Dyn-" + $_.BaseName + $_.Extension) \| Optimize-VHD -path $_.fullname}

I use the same file and folder name as the original but add an text before.

I use this for servers that are decommissioned but I do not want to delete. This way, they use not a lot of storage space.

Get folder permissions recursive

Posted on 24 September 2015 by Albert van Boerum Leave a comment

To view which user or group has access to a folder structure you must check this per folder.

Fortunately powershell has (ofcourse) the option to recursive check a folder structure and display the result in a nice textfile. The oneliner for this is:

Get-ChildItem -Recurse | where-object {($_.PsIsContainer)} | get-acl | format-list path,accesstostring > c:\permissions.txt

1	Get-ChildItem -Recurse \| where-object {($_.PsIsContainer)} \| get-acl \| format-list path,accesstostring > c:\permissions.txt

You can use the get-acl command to display the effective permissions on a folder. This commandlet does not have the option to recursive go trough the entire folderstructure. Get-Childitem has this option and when you pipe it trough get-acl you get the list you want.

The where-object {($_.PsIsContainer)} is used to only display folders and not files.

Create a share on a fileserver

Posted on 16 September 2015 by Albert van Boerum Leave a comment

In this post I’ll explain how to create a share on a fileserver, set permissions and other options for the share.

Prepare the server

To create a share on a fileserver, first make sure the the File Server role is installed on the server. This feature is installed by default.

Get-WindowsFeature fs-fileserver

1	Get-WindowsFeature fs-fileserver

Get the current shares

C:\Windows\system32> Get-SmbShare

1	C:\Windows\system32> Get-SmbShare

Create a new share

Fist make sure you have a folder on the server. Next create the share.

New-SMBShare -Path c:\marketing -Name Marketing -Readaccess Everyone -FullAccess Administrator

1	New-SMBShare -Path c:\marketing -Name Marketing -Readaccess Everyone -FullAccess Administrator

to remotely create the share add the -cimsession option to the command.

New-SMBShare -CimSession Fileserver1 -Path c:\marketing -Name Marketing -Readaccess Everyone -FullAccess Administrat

1	New-SMBShare -CimSession Fileserver1 -Path c:\marketing -Name Marketing -Readaccess Everyone -FullAccess Administrat

Change permissions on a share

You want to keep the share permissions as simple as possible. To grant more detailed permissions you can use NTFS permissions on the folder or files. Bare in mind that Deny rights overrule the Allow rights.

To view the current permissions on a share:

Get-SMBShareAccess -Name Marketing

1	Get-SMBShareAccess -Name Marketing

To add permissions to a share

Grant-SmbShareAccess -Name test -AccessRight Change -AccountName company\marketing

1	Grant-SmbShareAccess -Name test -AccessRight Change -AccountName company\marketing

To remove permissions from a share

Revoke-SmbShareAccess -Name Marketing -AccountName company\sales

1	Revoke-SmbShareAccess -Name Marketing -AccountName company\sales

Configure Access-based Enumeration

You can hide folders from users that have no access to them. This is called Access-based enumeration. To enable this on a share disables users to view the folders where they do not have at least read access:

Set-SmbShare -Name Marketing -FolderEnumerationMode AccessBased

1	Set-SmbShare -Name Marketing -FolderEnumerationMode AccessBased

Get the size of files in a folder structure recursively

Posted on 20 July 2015 by Albert van Boerum Leave a comment

To get the size of specific files in a folder structure, for example log files, use the measure-object command, based on a selection you make.

First set the servers you want to check

$servers = 'server1','server2'

1	$servers = 'server1','server2'

Next, set the location on those servers

$FromPath = "\\$server\c$\Program Files\Microsoft\Exchange Server\V15\Logging"

1	$FromPath = "\\$server\c$\Program Files\Microsoft\Exchange Server\V15\Logging"

Next, get the files, in this case older then 15 days, and only the logfiles. The recurse option lets you find files in the entire folder structure.

Get-ChildItem $FromPath *.log -File -Recurse| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-15) }

1	Get-ChildItem $FromPath *.log -File -Recurse\| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-15) }

Next, measure the result by adding the measure-command commandlet.

Get-ChildItem $FromPath *.log -File -Recurse| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-15) } | Measure-Object -Property length -Sum

1	Get-ChildItem $FromPath *.log -File -Recurse\| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-15) } \| Measure-Object -Property length -Sum

The output can be something like this:

Count    : 11271
Average  : 
Sum      : 795737267
Maximum  : 
Minimum  : 
Property : Length

Count : 11271

Average :

Sum : 795737267

Maximum :

Minimum :

Property : Length

If you want, you can do several thing with the output, like deleting old logfiles. The complete code for this would be:

$servers = 'server1','server2'
foreach ($server in $servers) {
    $FromPath = "\\$server\c$\inetpub\logs\LogFiles\W3SVC1"
    Get-ChildItem $FromPath -File| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-60) } | Remove-Item -Force

    $FromPath = "\\$server\c$\Program Files\Microsoft\Exchange Server\V15\Logging"
    Get-ChildItem $FromPath *.log -File -Recurse| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-15)} | Remove-Item -Force 
}

$servers = 'server1','server2'

foreach ($server in $servers) {

$FromPath = "\\$server\c$\inetpub\logs\LogFiles\W3SVC1"

Get-ChildItem $FromPath -File| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-60) } | Remove-Item -Force

$FromPath = "\\$server\c$\Program Files\Microsoft\Exchange Server\V15\Logging"

Get-ChildItem $FromPath *.log -File -Recurse| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-15)} | Remove-Item -Force

}

Remove old logfiles from Exchange servers

Posted on 20 April 2015 by Albert van Boerum Leave a comment

You can use Powershell to remove old logfiles from exchange servers. Those logfiles are located on the Client Access Servers (CAS servers) in the inetpub folders.

To remove the files older then 60 days use this script.

Fill in your own CAS servers on the variable $servers line. You can use as many as you want to.

# delete old logfiles from Exchange CAS servers
$servers = 'CASServer1','Casserver2'
foreach ($server in $servers) {
    $FromPath = "\\$server\c$\inetpub\logs\LogFiles\W3SVC1"
    Get-ChildItem $FromPath -File| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-60) } | Remove-Item -Force
}

# delete old logfiles from Exchange CAS servers

$servers = 'CASServer1','Casserver2'

foreach ($server in $servers) {

$FromPath = "\\$server\c$\inetpub\logs\LogFiles\W3SVC1"

Get-ChildItem $FromPath -File| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-60) } | Remove-Item -Force

}

Move files older then x hours

Posted on 31 March 2015 by Albert van Boerum Leave a comment

Schedule a task if you need to move files older then x hours to an other folder.

# Move files older then 3 hours to a folder via a scheduled task

$FromPath = "\\source server\share\"
$ToPath = "\\dest server\share"

Get-ChildItem $FromPath| Where-Object { $_.lastwritetime -lt (get-date).AddHours(-3) } | Move-Item -Destination $ToPath

# Move files older then 3 hours to a folder via a scheduled task

$FromPath = "\\source server\share\"

$ToPath = "\\dest server\share"

Get-ChildItem $FromPath| Where-Object { $_.lastwritetime -lt (get-date).AddHours(-3) } | Move-Item -Destination $ToPath
