The solution relies on: - A **secure OVHcloud S3**[**™\***](#go-further)** bucket** (Object Lock, versioning, lifecycle). - An **automated periodic backup** of the Prism Central configuration. - A **full restoration** is possible in case of a major incident.   ### Overview & benefits #### Main features - Point-in-Time backup of Prism Central to an OVHcloud S3™ bucket. - Automatic creation of **periodic restore points (RPO)**. - Full restoration from Prism Element. - Centralized management from **Prism Central**.   #### Benefits - Strong protection of critical Nutanix management data. - Backup externalization outside the cluster. - Data compliance and immutability. - Simplicity of operation and administration.   ## Requirements - Access to the [OVHcloud Control Panel](https://manager.us.ovhcloud.com/) - **Prism Central** version pc.7.5 or later - **Prism Element** must be operational   ## Instructions ### Preparing the environment #### Creating the Object Storage container (bucket) To create the container, you must first create a Public Cloud project. Refer to our guide: [Creating your first OVHcloud Public Cloud project](https://docs.us.ovhcloud.com/en/public-cloud/cross-functional/create-a-public-cloud-project.md). Navigate to the [Public Cloud universe](https://manager.us.ovhcloud.com/#/public-cloud/pci/projects/), choose your project, select `Object Storage`, and then `Create an object container`. On the following page: 1. **Name:** i.e., `prism-central-backup` 2. **Type:** `S3-compatible API` 3. **Location:** Choose the 1-AZ region that is **the same** as that of your cluster. 4. **Version management:** `Enable` 5. **Object lock:** `Enable` 6. **User:** Add an existing user or create a user, e.g., `admin-mst` **Note:** If you create a new user, note the **Access key** and **Secret key** in the pop-up that will appear. 7. **Encrypt your data:** `No encryption` Once the container is created, select the `General information` tab, and then click `Configure retention →` in the **Object Lock** panel. Choose the following configurations: 1. **Default retention:** `Enabled` 2. **Retention mode:** `Compliance` 3. **Retention period:** `31 days`   #### Configuring the "bucket lifecycle" **Warning:** **NOTE:** You can learn more about configuring the bucket lifecycle and delete markers in these guides: - [Object Storage - Getting started with versioning](https://docs.us.ovhcloud.com/en/storage-and-backup/object-storage/versioning.md) - [Object Storage - Smart storage management with lifecycle rules](https://docs.us.ovhcloud.com/en/storage-and-backup/object-storage/bucket-lifecycle.md) - Expire current objects version after: 31 days. - Expire previous/noncurrent objects version after: 1 day. - Delete expired delete markers: 1 day. - Delete expired failed/incomplete multipart uploads: 1 day. Install and configure the AWS CLI client. Refer to our guide: [Getting Started with Object Storage](https://docs.us.ovhcloud.com/en/storage-and-backup/object-storage/getting-started.md). Run this command by customizing the variables `BUCKET_NAME`, `ENDPOINT_URL`, and `PROFILE`: ``` BUCKET_NAME='prism-central-backup' ENDPOINT_URL='https://s3.us-east-va.io.cloud.ovh.us/' PROFILE='us-east-va' aws s3api put-bucket-lifecycle-configuration \ --bucket ${BUCKET_NAME} \ --lifecycle-configuration '{ "Rules": [ { "ID": "ExpireCurrentVersions", "Status": "Enabled", "Expiration": { "Days": 31 }, "Filter": {} }, { "ID": "ExpireNoncurrentVersions", "Status": "Enabled", "NoncurrentVersionExpiration": { "NoncurrentDays": 1 }, "Filter": {} }, { "ID": "DeleteExpiredDeleteMarkers", "Status": "Enabled", "Expiration": { "ExpiredObjectDeleteMarker": true }, "Filter": {} }, { "ID": "AbortIncompleteMultipartUpload", "Status": "Enabled", "AbortIncompleteMultipartUpload": { "DaysAfterInitiation": 1 }, "Filter": {} } ] }' \ --endpoint-url ${ENDPOINT_URL} \ --profile ${PROFILE} ```   ### Procedure – Configuring Prism Central point-in-time backup #### Accessing the configuration From the **Prism Central** web console, navigate to `Infrastructure` > `⚙️ Prism Central Settings` > `Prism Central Backups`. Select the `Point-in-Time Backup` tab and click `Protect Now`. The system supports **only one Point-in-Time backup target at a time**. If a Point-in-Time backup is already configured, the `Protect Now` button does not appear.   #### Configuring the backup target The **Protect Prism Central** window appears and indicates: - The services whose data is backed up. - The services not backed up. For the detailed list, refer to: - _Supported Services for PCBR_. - _Unsupported Services for PCBR – Implementation Considerations and Limitations_. Click on `Continue`, then fill in the following parameters: - **Endpoint Type**: `Other S3 Compliant Object Store`. - **Region:** Enter the region of your Object Storage bucket. - **IP Address or Host Name (HTTPS Only)**: `s3..io.cloud.ovh.us` - **Bucket Name**: Name of the bucket. Scroll down and fill in the remaining fields: - **Access Key**: Access key. - **Secret Access Key**: Secret key. - **Restore Point Objects (RPO)**: Frequency of creation of restore points (in hours). - The **first restore point is created immediately**. - Supported values are: `1, 2, 4, 6, 8, 12, or 24 hours`. - Up to **30 days of restore points** are retained for Prism Central restoration. Click on `Proceed`.   #### Synchronization and backup status The system synchronizes Prism Central configuration data to the S3™ bucket. - **During synchronization:** The displayed status is `Sync in progress` in the _Prism Central Backups_ dashboard. - **After synchronization:** The status changes to `Synced`, and the date and time of the last synchronization are displayed. The first backup starts immediately after validating the S3™ target and lasts **at least 15 minutes**. - After the first backup: Synchronizations continue automatically, and restore points are created according to the configured RPO cycle.   ## Go further [Nutanix official documentation](https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_7_5:mul-configuring-pointintime-backup-to-generic-s3-compliant-t.html) Browse all the [Nutanix guides](https://docs.us.ovhcloud.com/en/hosted-private-cloud/nutanix-on-ovhcloud/landing-page-nutanix-on-ovhcloud.md).
