Snapshots

Snapshots is a snapshot created based on a server’s disk.

Snapshots is a data backup method where a disk snapshot is used to create a fully usable copy of a disk in a server at a specified point in time, allowing for a quick rollback to the state when the snapshot was created after a disk failure.

Currently, the cloud management platform supports manual setup of disk snapshots and the creation of disk snapshots through automatic snapshot policies. Manual snapshots and automatic snapshots can be distinguished by their names.

Automatic Snapshot naming convention.

  • The name of a snapshot created by Snapshot Policies on OneCloud platform is “Auto+Random 8-digit number”.
  • The name of the snapshot created by the Snapshot Policies on Alibaba Cloud platform is “auto2.0_yyyyMMdd_SnapshotPolicyId”, where yyyyMMdd is the date of the day and SnapshotPolicyId is the ID of the Snapshot Policies.
  • The name of the snapshot created by the Snapshot Policies on Tencent Cloud Platform is “snap_yyyyMMdd_HH”, where yyyyMMdd is the date of the day and HH is the hour.

  • After the cloud management platform is connected to the public or private cloud platform, it synchronizes the snapshot information of the disks on the public or private cloud platform.
  • Automatically create disk snapshots according to the Snapshot Policies.
  • Manually create disk snapshots in the disk list or server list.

Caution for manual snapshot creation.

  • VMware platform and UCloud platform disks do not support creating snapshots.
  • Snapshot creation is not supported when the status of the server to which the disk belongs is abnormal or the disk is not mounted to a server.
