Data Protection and Snapshots

This section provides instructions for taking volume snapshots using the Portworx CSI driver on Nomad.

CSI Snapshot Lifecycle

The following steps will allow you to snapshot a Portworx CSI volume:

Create a file volume.hcl with the following content:

id           = "volume-1"
name         = "database"
type         = "csi"
plugin_id    = "portworx"
capacity_min = "1G"
capacity_max = "1G"

capability {
  access_mode     = "single-node-reader-only"
  attachment_mode = "file-system"
}

capability {
  access_mode     = "single-node-writer"
  attachment_mode = "file-system"
}

Create a volume using the above file:
```
nomad volume create volume.hcl
```

Create a snapshot of the above volume:

nomad volume snapshot create volume-1 snap-1

List all snapshots to see the one you've created:
```
nomad volume snapshot list
```
Delete the above snapshot:
```
nomad volume snapshot delete snap-1
```

note

Snapshots with authorization and authentication enabled

Due to a few limitions with Nomad, Portworx authorization and authentication will not work with snapshotting. You can track the following issues for information on this support:
