Cloudify Backup and Restore Guide


Snapshots provide a way for the state of Cloudify HA cluster. A cloudify snapshot should be done on a daily basis (suggest in an off peak time) and can be automated using the REST API as an alternative to an operator manually running the snapshot as shown here in this user guide.

Backing up the virtual machine that the cloudify managers run on should be done at regular intervals, this would be dictated by a backup policies and would likely involve daily, weekly, monthly and yearly backups as required. The method for backing up the Cloudify Manager virtual machines falls outside the scope of this document.


Snapshots of the Cloudify HA cluster should be taken at regular intervals (suggest daily), this can be automated through the REST based Service API or can be done manually by an operator using the UI or CFY CLI. The screenshot below shows the menu presented to the operator when the settings button (i.e. cog icon on the right top of the menu) is clicked.

Creating snapshot

  1. Create snapshot:

    Code Block 1 CLI

    cfy snapshots create —include-metrics —include-credentials SNAPSHOT_ID

    Code Block 2 REST

    curl -X PUT --header "Tenant: <manager-tenant>" -u <manager-username>:<manager-password> "http://<manager-ip>/api/v3.1/snapshots/<snapshot-id>"

    Parameters specification available in the Cloudify API documentation.

  2. Download snapshot:

    Code Block 3 CLI

    cfy snapshots download [OPTIONS] SNAPSHOT_ID

    Code Block 4 REST

    curl -X GET --header "Tenant: <manager-tenant>" -u <manager-username>:<manager-password> "http://<manager-ip>/api/v3.1/snapshot/<snapshot-id>/archive" > <snapshot-archive-filename>.zip

    Parameters specification available in the Cloudify API documentation.

Applying snapshot

  1. Upload snapshot

    Code Block 5 CLI

    cfy snapshots upload [OPTIONS] SNAPSHOT_PATH

    Code Block 6 REST

    curl -X PUT
    --header "Tenant: <manager-tenant>"
    -u <manager-username>:<manager-password>

    Parameters specification available in the Cloudify API documentation.

  2. Restore snapshot

Code Block 7 CLI

cfy snapshots restore [OPTIONS] —tenant-name <TEXT> SNAPSHOT_ID

Code Block 8 REST

curl -s -X POST

--header "Content-Type: application/json"

--header "Tenant: <manager-tenant>"

-u <manager-username>:<manager-password>

-d '{"tenant_name": "<manager-tenant>", "recreate_deployments_envs": true, "force": false, "restore_certificates": false, "no_reboot": false}'


Parameters specification available in the Cloudify API documentation.

Failure Recovery

Whole cluster down or working wrong

  1. Save /etc/cloudify/ssl/* files.
  2. Teardown managers.
  3. Install fresh managers with existing certificates in /etc/cloudify/config.yaml.
  4. Create and join cluster.
  5. Apply latest working version snapshot on active manager.

One manager cluster node down

  1. Remove manager from the cluster.
  2. Destroy manager.
  3. Bootstrap fresh manager.
  4. Join existing cluster.

Effect: Healthy manager cluster

Active manager node down

  1. Other healthy manager from the cluster automatically becomes active manager.
  2. Investigate error:
  3. Either:
    • Fix problem
    • Destroy manager.
      1. Install manager.
      2. Join cluster.

Effect: Healthy manager cluster

Split brain

Description: Situation happens when for a while there is no connectivity between managers. Then each of them thinks that other managers are unhealthy and become master. After connectivity is back master becomes only one in cluster. It’s chosen based on the newest version of PostgreSQL database. All data from other managers will be synced with the active one and others will become standbys. All data/installed deployments/plugins will get lost.
