vm-snapshot-create

Usage

avcli vm-snapshot-create [--volumes | --no-data][--description "description"] [--desire] [--require] vm-name

Description

The vm-snapshot-create command creates a VM snapshot.

Two snapshot consistency levels are supported:

Crash consistency: The restored data is in the same state that it would have been if the system had crashed at the exact moment that the snapshot was taken. A crash-consistent snapshot does not capture the contents of memory or any pending I/O operations.
Application consistency: Before the snapshot is taken, cooperating applications are briefly frozen so that transactions are complete, buffers flushed, files closed, and so on. This ensures that cooperating applications start from a consistent state. This is the highest level of consistency.

Options

--volumes |

--no-data

The names of volumes to include in the snapshot. By default, all volumes are included in the snapshot unless you specify --volumes with individual volume names or you specify --no-data. If you specify --no-data, no volumes are included in the snapshot. These arguments are mutually exclusive.

--description "description"

The user-specified description for this snapshot.

--desire

The highest consistency level to attempt in order to declare the snapshot a success. If this attempt fails, attempts are made at successively lower levels (but no lower than the level specified by --require). Values are crash and application (the default value).

--require

The minimum consistency level needed to declare the snapshot a success. Values are crash and application (the default value).

vm-name

The VM's ID.

Examples

$ avcli vm-snapshot-create --volumes volume:o100 volume:o101 --description "This is the snapshot description" --name snapshot_name vm1
