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:

1. 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"
   }

2. Create a volume using the above file:

   nomad volume create volume.hcl

3. Create a snapshot of the above volume:

   nomad volume snapshot create volume-1 snap-1

4. List all snapshots to see the one you’ve created:

   nomad volume snapshot list

5. Delete the above snapshot:

   nomad volume snapshot delete snap-1
