How to create a KVM virtual machine backup?

Creating a backup is an important task for ensuring the security and preservation of virtual machine data. In this article, we will show you how to create a KVM virtual machine backup using commands in the terminal.

Before you start, make sure you have the qemu-img package installed, which allows you to work with disks in the qcow2 format.

To create a KVM virtual machine backup, follow these steps:

• Stop the virtual machine using the command virsh shutdown VM_NAME.
• Copy the virtual machine disk files using the command cp DISK_NAME.qcow2 BACKUP_NAME.qcow2.
• Start the virtual machine back up using the command virsh start VM_NAME.

Now you have a KVM virtual machine backup that you can use in case of failures or data loss.

Don’t forget to create regular virtual machine backups to ensure data security and preservation.
