| How to create a backup | You do not need to shut down the server or install software to create a backup.
You can: | We recommend shutting down the server before creating the image.
Create an image from the disk in the control panel or through the OpenStack CLI | You don't need to shut down the server or install software to create a snapshot.
Create a snapshot of the disk in the control panel or through the OpenStack CLI |

| How to restore a backup | When you restore from a backup, a new disk is created — you can connect it to an existing server, create a new cloud server, network disk, or image from it. You can only restore a full disk from a backup | The created image is stored in the image repository — you can create a cloud server or network drive from it | You can create a cloud server, network drive, or image from a snapshot |

| How many backups can be stored at the same time | - If backups are created automatically on a schedule, the total number of backups in the project is unlimited. You cannot create more than 90 full backups or 14 incremental backup chains of one disk within one plan;
- if backups are created manually, no more than 1000 backups in one project
| The quantity is limited only by the project's image limits — they can be increased through technical support | No more than five snapshots for one disk |

| Storage reliability | Backups are stored with triple replication on Servercore servers separate from disks, but in the same pool segment. You cannot change the storage location | Stored on Servercore servers separately from disks, but in the same pool segment. You cannot select the storage location. To improve storage reliability, you can move the image to another pool segment or download it and move it to a third-party infrastructure outside of Servercore | Stored on the same hardware as disks — so a snapshot is not a full backup. A snapshot is always deleted along with the disk |
