How To Choose The Right VMware Backup Solution? If you’re a VMware client, you’re aware that backup of the virtual machine (VMs) is the primary concern for keeping your data secure.
If you manage the VMware infrastructure, you face many risks for data such as ransomware attacks, deliberate and accidental deletions power failures.
By backing up those VMware Virtual Machines you will be able to guarantee the recovery of your data following a disruption.
The market today offers a wide range of VM backup software. To pick the right backup software for VMware that will meet your business’s needs first, you must define the qualities that your VMware backup software should have.
When you’ve established what you’re looking to find You can look through the various VM backup options and select the one that offers everything you need.
In this post, you will learn about the best features you’d want to incorporate as components in your VM backup strategy.
Recover, Backup, And Storage
If you’d like the process of recovering and backing up your data to run smoothly and reliably, concentrate on the three major elements of data protection Backup, storage, and recovery.
First, run efficient backups. Then, identify the locations of your storage. Finally, you can recover your data, but only if you have to do this! The three components above are interconnected and work together. Be aware that you cannot restore your data without a safe data backup or storage.
Modern VM backup tools have the latest backup storage, recovery, and backup capabilities that will take secure data to the top of the line. Let’s take a look at their key attributes and features.

1. Backup
Check to see if your backup software has these features and features which can help ensure that your backup process is quick and efficient.
A. Image-based
A backup that is image-based captures the entire VM starting from the A-Z, by creating an image of the whole VM together with its OSs, disks as well as configuration and file files.
A backup service that is based on images is agent-free, meaning you don’t have to run an agent installation on each VM. Instead, the agent is installed via an outside server. The agent is able to receive information from each VM it safeguards.
The process works using images according to the following before you make the backup, your backup program creates an image of your OS.
During this time when all other operations stop for a short time. When the state of your virtual machine is recorded, all activities resume.
The snapshot can be created as a backup which is then sent to a backup repository when you VM operates. The ability to stop the VM and then create a backup of its entire contents allows you to create an app-wide backup.
B. Incremental
A reliable VM backup solution can create incremental backups that rely on Changed Block Tracking (CBT) technology.
In an incremental backup, your backup software copies the data blocks in which the data has changed over your previous backup.
Modern backup tools typically implement Block-level, incremental backups. There are however other kinds of backups that have increments at the file or the byte level.
Additionally, the incremental backup method has many strategies:
- Regular Incremental Backups are only the blocks of data that have changed with a complete backup that is performed every week.
- Indefinite Incremental The full copy of the backup must be first created. After that, all backups are incremental.
- Reverse Incremental Synthetic backups are created with every incremental backup task. It’s used to immediately restore your VMs.
- Forty-Forever Incremental The first backup complete is created when the number of recovery points is greater than the amount specified in the policy on retention.
- Multilevel Incremental Backups are assigned levels 1, 2, and 3. Full backups have level zero. Every level has changed from the previous backup.
It is possible to use these backup methods depending on your personal circumstance. In general incremental backups can accelerate the process of backup and can save you a lot in storage.
C. App-consistent
As we’ve already discussed that image-based backups are the most efficient method of backing your data. Backups using images can also be consistent with your app.
This means that the data across different applications and databases is identical when you take the backup. The goal is to make sure that all transactions, including waiting ones, are components of the backup.
The consistency of transactions on the Windows machine can be achieved through the use of Microsoft Volume Shadow Copy Service (VSS). On a Linux system, it may make use of pre-freeze and post-thaw scripts to establish app data consistency.
D. Make Copies
Backups could be a victim of ransomware or be erased. This is why it’s important to make a backup copy.
It is possible to store a backup duplicate offsite or on tape or even in a cloud. This eliminates one source of failure.
A reliable backup tool can help you make backup copies in a timely manner and also create a backup of your backup repository as an alternative. You can also choose which backups you would like to be copied.
E. Verification
For the security and quick restoration of data in the event of an interruption, it is essential to have a functioning and complete backups from the beginning.
It’s too late if you discover that your backup is not working just when you require it most. To avoid an unpleasant surprise, make sure you check your backups after you have completed the backup task.
A reliable backup solution allows you to test backups by starting the VM or observing the heartbeat of the VM.
F. Policies
A modern backup system allows users to automate all the major jobs making use of policies. It can be automated to create backup jobs and then run them.
You can add the VM to the backup job according to parameters like the name of the VM’s owner, size or tag. You should also be able to remove VMs you don’t require from the backup task in a way that is automatic. Automation will help you save time by keeping backups in operation while you concentrate on other things.
G. Storage Snapshots
If your VMs handle a lot of data in a backup you should consider backing up using storage snapshots when the storage is of enterprise quality such as HPE 3PAR StoreServ as an instance. Backups made from storage snapshots follow three steps:
- The creation from the VM snapshot
- Create the snapshot of storage;
- The removal of VM snapshot
The entire process is extremely rapid. The snapshot itself takes up very little space, which helps save space in storage and decreases the burden of the environment for production.

2. Recovery
In terms of recovery, There are many alternatives. Pick the most appropriate recovery method in your particular situation.
A. Full
In rare instances, it is possible to take a complete backup on your VM. The reason behind a full backup could be due to a cyberattack or system malfunction that caused a massive loss of data.
A solid backup solution will allow you to restore your VMs from a prior date. You can use a grandfather-father-son (GFS) rotation scheme to recover your data from any point in time.
If you are performing a recovery then your solution creates an exact copy of the backup and then transfers that image to the new production server. The fresh VM is created and does not affect the original VM.
B. Instant Granular
There are occasions that you do not need to do a complete recovery. It happens when a specific item, folder or object is deleted within a critical program (like Microsoft Exchange, Active Directory and Microsoft SQL).
You will be able to make use of the search feature of the backup software to locate items that you want to restore in backups.
Once you have located the item, you are able to immediately recover it using the granular recover feature. Granular recovery will save you time while cutting costs and reducing the time to repair.
C. Instant Full
When your RTOs seem in a tight spot and you aren’t able to afford any downtime, you must figure out – “how to restore your VMs quickly?”
How do you accomplish this? Modern backup software allows you to run VMs directly from backups that have been deduplicated.
The whole process is completed in a flash, which means you don’t have to worry about the need to start a complete recovery. After your newly-booted VMs are operational and you are able to move them to production on an ongoing basis. The entire process won’t alter the backup you made originally.
C. P2V
Did your workstation or server suddenly stop working? If so, you’ll have to restore your work in the shortest time possible to avoid any downtime.
It is possible to do this by restoring physically Windows as well as Linux servers using backups to create virtual machines if you’re in an environment that is a mix of physical and virtual. Recovery is super speedy because you start your VMs from backups of physical machines.

3. Storage
To ensure the security of your data to protect your data, ensure you have the proper storage areas, so that you can store your files and decrease the size of backups in order to reduce storage.
A. Location
In the case of storage facilities, think about a variety of choices. The 3-2-1 strategy calls for having at minimum 3 backup copies.
Keep two copies on various storage media and keep one copy off-site. You can save backups in a cloud that is accessible to the public or on tape.
The more storage options you have, the safer your information will be. Let’s suppose that one of your backups gets damaged and it’s a frequent scenario. The best option is to recover your data from a backup location with an unaltered duplicate of your information.
B. Size-reduction
A reliable backup solution provides methods to reduce size in order to address the issue of storage space. Techniques for reducing size include:
- compression: The process works by changing the original code to use less storage. The compression software looks for patterns that repeat. Once they are discovered, the patterns are substituted with smaller codes. This greatly reduces the amount of data you have.
- Deduplication This solution compares new blocks of data to the backup repository. If duplicates are detected the duplicates are not duplicated. Instead, there is a reference to the original block is made.
- Backups incremental: Make use of CBT (Changed Block Tracking) (CBT) in order to backup only the data blocks which have been changed from your last backup. This method creates smaller backups and decreases storage space.
- Partitions and files that are swapped: Swap data can consume a lot of space. That’s why it’s damaging to backups. A sensible backup software VM allows you to switch partitions and files during the backup.
C. Other Important Points
Alongside the important attributes outlined above, additional aspects to take into consideration when deciding on your data protection include:
D. Network
You’re looking for a fast backup. So, you require an extremely fast network speed. A VM backup solution that has the ability to accelerate network speeds can double the speed of backups both over LAN and WAN.
It is also possible to reduce the burden on your production and get high-quality backups by using LAN-free transfers:
- Hot Add Data is read directly from the storage devices in the VMs This reduces the workload of your virtual machine and increases the speed of the data transfer.
- Direct access to SANs: Read data directly from Fibre Channel or iSCSI storage area network (SAN). Therefore, this software is very well with VMs situated on these servers.
E. Scalability
Whatever the size of your company your backup solution needs to be able to adjust to changes. If your infrastructure expands or shrinks, alter your backup plan and recovery strategy in line with the changes.
F. Pricing
You’ll want a VM backup solution that is effective and cost-effective simultaneously. Examine the various Backup VM backup software options that are on the market to find the most suitable one for your budget. The most practical licensing model is generally by socket or per job.
