Instance snapshots console¶
Overview¶
Instance snapshots can be used for backup purposes, to create new instances with identical configurations, or to roll back to a previous state in case of errors or issues.
Select Compute > Instance Snapshots to display the snapshots console. The console displays a list of existing snapshots.
For each snapshot, you can take the following actions:
- Edit
- Create instance
- Create volume
- Delete
Note
Taking a snapshot of an instance can impact its performance, as it requires freezing the file system and copying disk data. Additionally, snapshots capture only the root disk of the instance. Any data on attached volumes or ephemeral storage is not included in the snapshot and needs to be backed up separately.
Instance snapshot details¶
When creating or managing instance snapshots in the Compute service, you should be familiar with several properties and attributes associated with snapshots. Here's a list of key properties and attributes:
| Property/Attribute | Description |
|---|---|
| Name | A human-readable name for the snapshot, used for identification purposes. |
| ID | A unique identifier automatically assigned to the snapshot by OpenStack. |
| Status | Indicates the current state of the snapshot (e.g., queued, saving, active, deleted). |
| Visibility | Determines who can access the snapshot (public or private). |
| Protected | A boolean value indicating whether the snapshot is protected from deletion. |
| Disk Format | Specifies the format of the snapshot (e.g., raw, qcow2, vmdk, iso). |
| Container Format | Describes the container format of the snapshot (e.g., bare, ovf, aki). |
| Size | The size of the snapshot file in bytes. |
| Checksum | A hash value used to verify the integrity of the snapshot file. |
| Tags | A list of user-defined tags associated with the snapshot for categorization or filtering. |
| Instance ID | The ID of the instance from which the snapshot was created. |
| Volume ID (if applicable) | For snapshots created from a volume, the ID of the source volume. |
| Owner | The ID of the project or user that owns the snapshot. |
| Created At | The timestamp indicating when the snapshot was created. |
| Updated At | The timestamp indicating when the snapshot was last updated. |
Understanding these properties and attributes is helpful for creating or managing instance snapshots in the your cloud projects.
