Revert to a Product Snapshot

You can use the VMware Aria Suite Lifecycle API to revert your VMware Aria Suite product to a snapshot created using VMware Aria Suite Lifecycle. Reverting to a snapshot restores the product to a former state.

For example, if a product upgrade fails, you can revert to a snapshot of the product that you created before attempting the upgrade.

The following procedure shows how to revert to a snapshot for VMware Aria Operations.

Prerequisites

Verify that all general prerequisites have been satisfied and that you have assigned your environment ID and product ID. See the prerequisites for Performing Day 2 operations using VMware Aria Suite Lifecycle APIs.
Verify that you have the ID of the snapshot that you want to revert to. See Create a Product Snapshot.
If you are reverting to a snapshot of VMware Aria Automation Config, verify that the tenant ID variable is assigned. See Creating and Managing Product Snapshots.

Procedure

Assign the snapshot ID variable.
```
snapshotId = '<your_snapshot_ID>'
```

Revert VMware Aria Operations to your_snapshot_ID. For a snapshot that was taken without memory, set "powerOn": true to power on the virtual appliance and restore the disk to its initial state.

curl -X POST \
  '$url/lcm/lcops/api/environments/$environmentId/products/$productId/snapshot/inventory/revert' \
  -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' \
  -H 'Content-Type: application/json' \
  -d '{
     "powerOn": true,
     "productSnapshotId": "'$snapshotId'"
}' | jq "."

Note: To revert to a snapshot of VMware Aria Automation Config, include the tenant ID as a query parameter in your request, for example:

curl -X POST \
  '$url/lcm/lcops/api/environments/$environmentId/products/$productId/snapshot/inventory/revert?tenantId=$tenantId' \
  -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' \
  -H 'Content-Type: application/json' \
  -d '{
     "powerOn": "true",
     "productSnapshotId": "'$snapshotId'"
}' | jq "."

The request triggers the API. The response shows the request ID.

{
    "requestId":"a3f77209-0005-44b3-9eb5-ac1a1ba19394"
}

Assign the variable for the requestId.

requestId = "a3f77209-0005-44b3-9eb5-ac1a1ba19394"

Use the requestId to track your request.
```
curl -X GET '$url /lcm/request/api/v2/requests/$requestId' -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' | jq "."
```
After the request succeeds, VMware Aria Suite Lifecycle has restored VMware Aria Operations to the state and configuration defined in the snapshot.
```

  "outputMap": {},
  "state": "COMPLETED",
  "executionId": "59430b9d-44cc-47a1-90ec-777481edb9z9",

```
On Manage Snapshot in the VMware Aria Suite Lifecycle product UI, a You are here marker shows the snapshot to which the product was reverted.
