Extract VM details from VCenter

Posted by Saugata

Sometimes it's a painful job to extract all the information from vCenter server. From GUI you could export information, but not all the information will be available. I was requested to extrach following information.

  • VM Name
  • Host Name
  • VM IP Address
  • Installed Guest OS
  • Power State of VM
  • Allotted number of CPU
  • Allotted total memory
  • Connected Data store
  • Host Server
  • Host Cluster

Set File System Auditing via PowerShell

Posted by Saugata

For last few days, I was trying to figure out how to set file system auditing via command line. I was looking for this as I had to apply some specific audit policy on multiple file servers. From GUI, we could do this, but it will take hours of manual activity.

As requirement, I had to set Success Audit policy on Delete subfolders and files, delete and change permission.

There are multiple tools available, but none of them have ability to apply specific policy, so I decided to try PowerShell, and finally able to apply those audit policy successfully.

AWS EBS Snapshots Automation (Disaster Recovery) from Windows PowerShell

Posted by Saugata

ebs

It is always a good idea to reduce hardware dependencies by moving your data to the cloud. Cloud is much more flexible than traditional hardware infrastructure including VMWare. But you still have to consider the ability of recovering data as and when required. This always helps you to keep your business running with minimal interruption. In AWS, there are several possibilities for implementing an effective backup strategy. EBS snapshots are so simple & cost effective. You can take snapshot easily from AWS Web console, but there is no option to configure scheduled backup to automate.

Being as a Windows Administrator, Initially I used AWS Tools for Windows PowerShell (AWS SDK for .NET) to manage snapshot using PowerShell cmdlets. There are some script available to automate the snapshot process, but most of them are available for Linux environment or way too complex for me to understand. Then I decided to write one script for myself, which should fulfil following requirement.

  • Take snapshot for all volumes.
  • Can be scheduled as per defined backup strategy.
  • All snapshots must follow proper naming convention with time stamp in its description.
  • Keep the logs¬†after finishing backup.
  • Remove old snapshots as per defined retention period.
  • Trigger one email after every successful execution of the script for taking & removing snapshot.


Finally I managed to write two separate script, one for taking snapshots and another for removing old snapshots. Also able to rotate this script to take backup as Daily, Weekly by duplicating the script and creating multiple scheduled tasks.

NOTE : I am not a pro on PowerShell, but I tried my best to write this script, and it works without any issue. As always, you can use this script at your own risk.
