GitHub user daviftorres edited a comment on the discussion: What does Snapshots, Backups, and Incremental Snapshots mean in CloudStack
We upgraded our Dev environment to 4.22, and we are testing instance and volume snapshots to visualize the incremental portion. I can confirm that **instance snapshots** sometimes use QCOW2's **internal snapshots**. <img width="907" height="436" alt="image" src="https://github.com/user-attachments/assets/ed118d7c-fe76-4715-abf8-ce985210603a"; /> Table `vm_snapshots` <img width="952" height="83" alt="Screenshot 2026-01-20 145759" src="https://github.com/user-attachments/assets/fe19196e-51c4-4002-8e21-a4a65632a9e8"; /> **Note:** I had to include memory because the instance snapshots could (in that occasion) only be taken when the instance is in the Running state. Please correct me if I am wrong. This instance was deployed from an ISO. Then, for no apparent reason on another instance that was deployed from a template to a unlinked sparse provisioning, it "decided" to take external snapshots. <img width="1072" height="997" alt="image" src="https://github.com/user-attachments/assets/e74c6b81-d220-4254-8820-01dcd3d84446"; /> It can also be observed on the XML Dump of the instance. <img width="533" height="420" alt="image" src="https://github.com/user-attachments/assets/02af123c-2c41-4474-b174-5e8536b358d0"; /> ***If you know what logic is used to define if the snapshot will be used for snapshots (internal or external), please comment below.*** GitHub link: https://github.com/apache/cloudstack/discussions/12475#discussioncomment-15553029 ---- This is an automatically sent email for [email protected].
