About Qcow2 Incremental Backup

Did you know that the qcow2 is a file format used to store VM disk images in QEMU/KVM-based virtualization environments?

In fact, it offers efficient storage as well as management of VM images with copy-on-write (COW) techniques in order to avoid data duplication.

Incremental backup involves backing up only the data that has changed since the last backup, which reduces backup time and storage requirements.

According to our experts, the Qcow2 incremental backup allows users to back up only the changes made to a qcow2 VM disk image since the last backup, rather than creating a new full backup each time. This goes a long way in reducing backup time and storage requirements, especially for large VM disk images.

Qcow2 incremental backup involves creating a snapshot of the VM disk image at a specific point in time. This snapshot represents the state of the virtual machine disk image at the time of the backup.

Changes made to the VM disk image after the backup are tracked with COW techniques, and only the changed data is backed up in upcoming backups.

Users can easily carry out a qcow2 incremental backup with tools like libvirt or qemu-img.

These tools include options to create snapshots of the VM disk image as well as perform incremental backups of the modified data since the last backup.

However, the Qcow2 incremental backup is not a complete backup solution. We have to use it along with other backup methods like full backups and disaster recovery plans. Furthermore, we have to test the backup solution regularly.
