Backups considered an essential requirement in this modern era plays a significant role in shaping up the business continuity of many Web Dependent Businesses. While backing up our Virtual Machines in VMware Environments, there are various factors which we believe, make our backup more reliable, efficient and easily restorable in case of any mishap. So what exactly is the Best VMware Backup Practices? Let us have a look :
VMware Backup Best Practices
There are certainly some major factors you need to look upon while giving a thought about VMware Backup. These factors contribute vastly in making your VMware Backup more reliable.
- Create a VMware Backup properly
- Your Snapshot is just a Snapshot and not a Backup
- Having your backup in an additional secondary location
- Understanding the exact meaning of replication and performing it efficiently on your backups
- Backup Encryption
Creating a VMware Backup Properly:
First, create a VMware Backup Properly because many times we might exclude the Virtual Machine from being backed up. This is one of the most basic practice to make your VMware Backup more reliable. Yes! a Virtual Machine can be recovered much faster than a Physical Machine, but as Human Beings there is something which we cannot control – Nature! Apart from these other pitfalls such as Malware attack exists which acts a hindrance. So basically, the first thing you need to have in mind is to “Backup your Virtual Machine properly”.
Your Snapshot is just a Snapshot and not a Backup:
Ever Wondered what the term “Snapshot Chain” Refers to? Virtual Machines are composed of certain specific files, Snapshot is also a part of these files. These files are dependent on the VM Disks. Hence they are referred to as a Snapshot Chain. So whenever a VMware Snapshot is taken and you think you have a backup. It is a Myth because they are just screenshots and not backups.
Having your backup in an additional secondary location:
In today’s Scenario, the most important aspect while dealing with VMware backups is having an additional backup copy. Why is this an important aspect?
When you have an additional backup copy offsite you are making sure that in case of any disaster, your backup copy is in a safe condition.
With the fear of Malware Attack or Ransomware these days affecting your backup data, be smart enough to have an additional backup copy. The reason why I’m mentioning smart is that hackers these days have started gaining access even to your production environment and you can imagine the dire consequences you have to face if you don’t have an additional backup copy.
Understanding the exact meaning of replication and performing it efficiently on your backups:
You need to have some basic knowledge on what replication is and how it differs from a backup. Your backup copy is just an another copy of your backup data. This is completely different from the term “Replication”. Replication is basically having an another copy of your Virtual Machine that has been replicated. Also, understand under what circumstances must Replication be performed. Ideally, the use case scenario for Replication is when you are facing some issues or failure in your production environment and you want to restore your Source VM’s to a secondary site. In this case, you can utilize Replication concept wherein you can restore your Source VM’s to a secondary site or to any other ESXi host. The biggest advantage of performing Replication through Vembu is that your data is kept up to date as well as the Replication process is very quick.
Among the VMware Backup Best Practices, Encryption surely has a vital role to play. Just like understanding the concept of Replication, you must have some basic knowledge on what encryption is while you are dealing with VMware Backups. People think to encrypt their data in order to protect it from Hackers, Ransomware, Malware or Data Theft. As far as VMware Backups are concerned, encryption is of two types: Encryption At Rest and On The Fly Encryption.
What is Encryption At Rest? Encryption At Rest is the concept of directly Encrypting your Backup Repository rather than encrypting your individual Backup Data. So now that you have encrypted your Backup Repository when hackers or intruders gain access to the Backup Data that is present in your Backup Repository, it will be of no use and not readable as they have no idea regarding the Encryption Key. Vembu offers built-in End to End Encryption to all its users.
Another Encryption technique involved with VMware Backup is On The Fly Encryption. This type of encryption is utilized during data transfer. Once the data transfer begins, the backup data is compressed and encrypted On The Fly from the source location to the Backup Repository.
There must be certain things we have to keep in mind while doing any task so as to get the best and fruitful result from it, VMware Backup is no exception. There are many other such practices along with the above-mentioned practices which ensure backup reliability and security for your VMware Backup.
