Understanding VMWare Snapshot Quiescing

by Mark | Jun 13, 2023 | HyperV, Microsoft HyperV, Snapshot / Checkpoint, VMWare

Introduction to VMWare Snapshot Quiescing

Snapshot quiescing, a technique employed in the world of virtualization, stands as a pivotal concept to grasp for anyone involved in IT operations. In particular, when working with VMware, understanding snapshot quiescing can significantly streamline your backup and restore operations. It’s a crucial process that ensures the data on a Virtual Machine (VM) is in a consistent state when a snapshot is taken. Imagine it as a photographer asking everyone to stay still for a moment to capture a clear picture. That’s precisely what quiescing does – it momentarily pauses or alters the state of running processes on a VM to get a clear, consistent snapshot.

Concept of VMWare Snapshots

Taking a snapshot is akin to capturing a moment in time. In VMware vSphere, snapshots allow you to preserve the state of a VM at a specific point in time. This includes the VM’s configuration settings, memory state, and disk state. Think of it as a time machine allowing you to go back to a particular moment when a change had not yet occurred or an error had not yet taken place. Snapshots are invaluable in situations like applying system updates or performing testing – if something goes wrong, you can simply revert the VM to the state it was in when the snapshot was taken, effectively undoing any negative impact.

The Quiescing Process

In essence, the quiescing process ensures that the data on a VM is in a consistent state suitable for backups. The operation of quiescing a VM suspends or alters the state of ongoing processes on a VM, especially if a particular process may modify stored data during a backup. When a snapshot is taken during the quiescing process, it represents a consistent view of the guest file system state at a specific point in time.

Understanding Types of VMWare Snapshots

Memory State Snapshots

Memory state snapshots are the default option for taking snapshots in VMware vSphere. They capture and retain the active state of a VM. For instance, if you’re running an application on your VM, a memory state snapshot will save the state of that application. If you revert to this snapshot later, the VM will return to that exact moment, with the application running in the same state. It’s important to note that memory state snapshots take longer to create than non-memory snapshots. The time it takes for the host to write the memory to disk is directly related to the amount of memory the VM is configured to use.

Quiesced Snapshots

On the other hand, quiesced snapshots are used when you need to perform operations on a VM that require a consistent state. The process of quiescing the guest file system ensures that a snapshot represents a consistent view of the guest file system state at a specific point in time. This involves suspending or altering the state of ongoing processes on a VM, especially those that may modify stored data during a backup.

To create a quiesced snapshot, VMware Tools must be installed and running on the VM. The process involves creating a new Volume Snapshot Service (VSS) snapshot inside the guest operating system using the VMware Snapshot Provider function, preparing active applications for backup with VSS writers, writing transactions from the memory to the disk, and signaling the completion of the writing process to the VMware Tools Service. At this point, the system is ready to take a quiesced snapshot. Quiesced snapshots are best used when you configure a VM for regular backups.

In terms of consistency, quiescing a VM achieves both file-system and application consistency. File-system consistency ensures that all file system metadata reflects the actual data on disk. Application consistency ensures that the application data is consistent with the application’s state. Quiescing is essential for highly transactional applications as it helps create transactionally consistent backups or replicas, guaranteeing the safety of application data.

Snapshots in VMware vSphere

Taking snapshots of a virtual machine (VM) in vSphere serves as a powerful tool in the management and protection of your data. These snapshots essentially capture a VM’s memory state, disk state, and configuration settings at particular moments in time, providing a robust mechanism for preserving the state of a VM.

With snapshots, you can effectively revert a VM to a state it was in before a snapshot was taken. This capability proves invaluable in scenarios such as testing new software or system updates. For instance, imagine you’ve just installed a new operating system on your VM. By taking a snapshot before applying any significant changes, such as updates or software installations, you establish a safety net. If any issues arise from these changes, you can effortlessly revert back to the state when the snapshot was taken, effectively undoing any problems.

However, it’s important to note that the process of taking a snapshot can be influenced by the ongoing activities on a VM. As such, snapshots are most effectively taken when a VM is not running I/O-intensive tasks or programs that are constantly communicating with other machines. This is because active data transfer or communication during a snapshot can lead to errors. For instance, if a snapshot is taken during the transfer of a file from a server to a VM, the file in question could appear to be corrupted when you revert back to that snapshot.

Memory State Snapshots vs Quiesced Snapshots

In the realm of snapshots, there are two primary types you can create in a VMware vSphere environment: memory state snapshots and quiesced snapshots. The choice between these two largely depends on your specific needs and the operations you intend to perform on a VM.

Memory state snapshots serve as the default option for taking snapshots in VMware vSphere. They capture and retain the active state of a virtual machine, allowing a running VM to be reverted to the state it was in when the snapshot was taken. This type of snapshot is ideal when you need to save the state of running applications. However, it’s important to note that memory snapshots take longer to create than non-memory snapshots. The time it takes the host to write the memory to disk is directly related to the amount of memory the VM is configured to use. It’s also recommended to avoid using memory snapshots as a replacement for true backups as they don’t provide the same level of data protection and recovery.

On the other hand, quiesced snapshots involve a process known as quiescing the guest file system. Quiescing essentially means bringing the data on a VM into a state suitable for backups. Backup solutions often use VM snapshots to copy data from a VM. The operation of quiescing a VM ensures that a snapshot represents a consistent view of the guest file system state at a specific point in time. This is particularly important if a process might modify stored data during a backup. Quiesced snapshots are most effective when you configure a VM for regular backups.

Quiesced Snapshots and the Importance of Quiescing

Quiescing a VM’s file system is crucial for creating a snapshot that represents a consistent view of the file system state at a specific point in time. This consistency is essential for backups and achieving both file-system and application consistency. During the process of creating a quiesced snapshot, the guest OS’s active applications are prepared for backup using VMware Tools and the VMware Snapshot Provider function, which creates a new Volume Snapshot Service (VSS) snapshot inside the guest operating system. As part of this process, transactions are written from memory to disk, and once the writing process is complete, a quiesced snapshot is taken.

There are two types of consistency to consider when quiescing a VM: file-system consistency and application consistency. File-system consistency refers to the state where all file system metadata reflects the actual data on disk. Application consistency, on the other hand, ensures that the application data is consistent with the application’s state. Quiescing is essential for highly transactional applications as it helps create transactionally consistent backups or replicas, guaranteeing the safety of application data.

However, obtaining more detailed, step-by-step information on the process of creating quiesced snapshots in VMware proved to be challenging within the given time frame. I recommend consulting the official VMware documentation or reaching out to a VMware technical support resource for a more thorough explanation.

Cloud repatriation is not a new phenomenon but has gained significant attention recently. The initial appeal of the cloud was undeniable, with its promise of unlimited scalability, reduced hardware costs, and access to advanced technologies. However, as businesses dived into the cloud, certain issues began to surface. Some companies found their cloud expenditures spiraling out of control, while others discovered that their specific workloads didn’t perform as well in the cloud as they did on-premise. Then there were issues related to compliance and data sovereignty.

All these factors combined, led businesses to rethink their cloud strategies and consider the option of cloud repatriation. But why are businesses considering cloud repatriation, you might ask? Well, there are several factors at play here. Cost considerations, the need for greater control, security concerns, and performance issues are some of the leading drivers for businesses to move their workloads back on-premise. However, the process of repatriation is not straightforward.

There are several challenges that businesses need to overcome. It requires careful planning, selecting which workloads to move, preparing the on-premise environment, and actually moving the data and applications. It’s not just a simple case of ‘lifting and shifting’. It involves considerable time and resources and needs to be done in a manner that minimizes business disruption.

In the next few paragraphs, we will delve into the Azure Cloud, understand its benefits and common use cases, and why businesses might want to move away from it to an on-premise environment. We will then explore the process of Azure Cloud Repatriation and how businesses can simplify it with the help of Carbon, a software tool developed by SmiKar.

While Azure’s global footprint allows businesses to deploy their applications close to their customers, there might still be performance issues or latency, especially for businesses serving a local or specific geographic market. In such cases, hosting the applications on-premise might provide a better user experience.

The Process of Azure Cloud Repatriation

The process of repatriating workloads from Azure Cloud to on-premise environments can be complex and requires careful planning.

Planning for Repatriation

Before initiating the repatriation process, businesses need to thoroughly evaluate their workloads and identify which ones would benefit from being on-premise. They need to consider the costs, performance requirements, and security and compliance requirements of these workloads.

Selecting VMs for Repatriation

Once the workloads have been identified, the next step is to select the Virtual Machines (VMs) on Azure that host these workloads. These VMs would need to be replicated and migrated back to the on-premise environment.

Preparing the on-premise environment

Finally, before the repatriation can begin, the on-premise environment needs to be prepared. This includes setting up the necessary hardware, configuring the network, and setting up the virtualization platform, whether it’s VMware or Hyper-V.

This process, while necessary, can be time-consuming and complex, especially for businesses with large numbers of VMs or complex applications. This is where Carbon, a software tool developed by SmiKar, can help.
