Veeam makes backups by telling the virtualization software to take pictures of virtual machines (VMs). These pictures show everything about the virtual machine (VM), including its setup, memory, and virtual hard drives. The snapshot can be used as a short-term copy for Veeam to use.

At a basic level, Veeam can get data from virtual machine (VM) disks and only copy the parts that have changed since the last backup. VMware’s Changed Block Tracking makes it easier to do this by reducing data transfers and speeding up backups. Before saving the data in its special format in the backup storage, Veeam makes the data smaller and copies it.

Here are some of the backup choices Veeam provides:

• Full backups create a complete copy of the entire virtual machine at a specific moment.
• Incremental backups save only the new or changed data since the last backup.
• Reverse incremental backups are a method where a complete backup is made by using a series of smaller, incremental backups. Incremental backups are great for storing information for a long time

Veeam’s Instant Recovery can start a working virtual machine right from a backup file in just a few minutes. This method helps minimize the time lost during emergencies. Veeam can also restore specific types of data, like SQL database transactions, in a way that recognizes the applications involved.
