Snapshots section

Volume snapshot is a base, on which many volumes can be created. In addition, snapshot can be used as a backup.

Attention! In the current implementation, a snapshot creation procedure may only be started when there is no data writing to the volume (the volume is unattached or instance is stopped).

Creating a snapshot

Snapshot can be created using several methods:

  • when creating a template from a stopped instance, snapshots of all volumes attached to this instance are created automatically;
  • snapshot can be created from a file uploaded to bucket;
  • snapshot can be created from the specified volume.

When creating a snapshot, it gets a unique ID in the snap-XXXXXX form. We recommend you to give each snapshot a brief description for convenience.

By default, snapshots are private. You can give an access to a snapshot for projects or by making the snapshot public (in this case all authorized CROC Cloud users will be able to create volumes based on your snapshot). If the snapshot contains OS boot image, then you have to ensure quality and security of instances created from this snapshot before allowing other users to access it. It is strongly recommended to avoid distributing snapshots with a preset system administrator password. A random password can be generated at the system launch and displayed to user via remote console.

Be careful when using licensed software. License cloning is not allowed in some cases.
