Configuring Snap-to-Object in WEKA

WEKA NeuralMesh's Snap-To-Object capability exports point-in-time filesystem snapshots (data and metadata) directly to Wasabi with a full first snapshot and incremental snapshots after that. In this article describes the steps to send an on-demand snaphshot to Wasabi and configure snapshot policies.

Requirements

• WEKA cluster version 4.4.35 or higher

  • Data Protection Option (DPO) license

• An active Wasabi account

  • Access & Secret Key Pair (see 3—Creating a User Account and Access Key)

  • Wasabi bucket (see 2—Working With Buckets and Objects)

On-demand snapshots

1. Navigate to Manage.

2. Select Snapshots.

   

3. On the Snapshots page, click + Create to create a snapshot.

   

4. In the Create Snapshot dialog box, provide the following details.

   • Name—Provide a name for the snapshot.

   • Access Point—Name of the directory created for the filesystem-level snapshot.

   • Source Filesystem—Source filesystem from which to create a snapshot.

   • Upload to local object store—Enable this to upload the snapshot to local object store.

   • Upload to remote object store—Enable this to upload the snapshot to remote object store (if the filesystem has a remote object store configured).

5. Click Create.  

   

   The Snapshots page will display the snapshot progress.

   

Creating a Snapshot policy

1. Navigate to Manage.

2. Select Snapshot Policies.

   

3. On the Snapshot Policies page, click + Create Policy.

   

4. Provide a name for the policy.

5. Specify how often the snapshots should be uploaded to the Object store.

6. Click Save.

   

7. On the Snapshot Policies page, select the policy created earlier.

8. Under the Assigned Filesystems section, click Attach Filesystem.

   

9. Select the Wasabi filesystem.

10. Click Attach.

    

11. The snapshot policy will display the attached filesystem.

    

    According to the configured policy, the snapshots will be uploaded to the Wasabi bucket.

Restoring a Snapshot

1. Navigate to the snapshot in which to restore.

2. Expand the options and select Restore To.

   

3. Select the destination in which to restore the snapshot.

4. Click Save.

   

Appendix

This section provides the command line approach to the above configuration.

1. Take a snapshot.

   weka fs snapshot add <fs> <snap-name>

2. To create a snapshot policy, export the default policy and edit the JSON. Use the following commands.  

3. Add the policy.

   weka fs protection snapshot-policy add <name> <path> [--description <string>] [--enabled]

4. Attach filesystems to the policy.

   weka fs protection snapshot-policy attach <name> [<filesystems>]...

5. Restore a snapshot.

   weka fs restore <fs> <snap> --preserved-overwritten-snapshot-name <name>
