Back up your workloads

Autopilot Standard

This page describes how to create a backup of your workloads in Google Kubernetes Engine (GKE) using the Backup for GKE service.

Introduction

Two forms of data are captured in a backup:

Config backup: A set of Kubernetes resource descriptions extracted from the API server of the cluster undergoing backup.
Volume backup: A set of volumes that correspond to PersistentVolumeClaim resources found in the config backup.

If your backup plan defines a schedule for the backup, the backups are automatically created according to that schedule. You can also create a backup manually. For example, you might want to back up your workloads before you upgrade your applications.

Before you begin

Create a backup plan.

Create a manual backup

You can manually create a backup for a backup plan by using the Google Cloud CLI or the Google Cloud console.

gcloud

Run the following command:

gcloud beta container backup-restore backups create BACKUP \
    --project=PROJECT_ID \
    --location=LOCATION \
    --backup-plan=BACKUP_PLAN \
    WAIT_OPTION

Replace the following:

BACKUP: the name of the backup that you want to create.
PROJECT_ID: the ID of your Google Cloud project.
LOCATION: the compute region of the parent backup plan.
BACKUP_PLAN: the name of the parent backup plan that this backup is derived from.
WAIT_OPTION: defines when the command should return:
- --async: The command returns as soon as the service acknowledges receipt. Will return almost immediately.
- (default): The command will return once the service has instructed the agent in the cluster to begin the backup process. Will usually return within a few seconds.
- --wait-for-completion: Wait until the agent has completed the backup operation in the cluster. May take several minutes.

For the full list of options, refer to the gcloud beta container backup-restore backups create documentation.

Console

Perform the following tasks in the Google Cloud console:

Go to the Google Kubernetes Engine page in the Google Cloud console.

Go to Google Kubernetes Engine
In the navigation menu, click Backup for GKE.
Click the Backup Plans tab.
Expand the cluster and find the plan that you want to create a backup for.
Click Start a backup.
Enter a backup name and optional description.
(Optional) Set the number of days to retain the backup before the backup is automatically deleted.
(Optional) Set the number of days during which backups cannot be deleted.
Click Start backup.

View a backup

View a backup and its details by using the gcloud CLI or the Google Cloud console.

gcloud

To list all the backup plans for a backup plan, run the following command:

gcloud beta container backup-restore backups list \
    --project=PROJECT_ID \
    --location=LOCATION \
    --backup-plan=BACKUP_PLAN

For list commands only, you can provide "-" as the value for any parameters except PROJECT_ID and - acts as a wildcard. - is the default value for any parameter if you do not specify a command-line option or set a property.

For the full list of options, refer to the gcloud beta container backup-restore backups list documentation.

To see the details of a backup, run the following command:

gcloud beta container backup-restore backups describe BACKUP \
    --project=PROJECT_ID \
    --location=LOCATION \
    --backup-plan=BACKUP_PLAN

For the full list of options, refer to the gcloud beta container backup-restore backups describe documentation.

Console

Perform the following tasks in the Google Cloud console:

Go to the Google Kubernetes Engine page in the Google Cloud console.

Go to Google Kubernetes Engine
In the navigation menu, click Backup for GKE.
Click the Backups tab.
Expand the backup plan and click the backup name.

View a volume backup

Volume backup resources are automatically created by the agent when PersistentVolumeClaims are encountered within the scope of a backup. Each volume backup corresponds to a persistent disk snapshot. These resources are created and managed by the agent automatically as part of the backup operation.

View a volume backup and its details by using the gcloud CLI. To list all the volume backups for a backup, run the following command:

gcloud beta container backup-restore volume-backups list \
    --project=PROJECT_ID \
    --location=LOCATION \
    --backup-plan=BACKUP_PLAN \
    --backup=BACKUP

For the full list of options, refer to the gcloud beta container backup-restore volume-backups list documentation.

To see the details of a volume backup, run the following command:

gcloud beta container backup-restore volume-backups describe VOLUME_BACKUP \
    --project=PROJECT_ID \
    --location=LOCATION \
    --backup-plan=BACKUP_PLAN \
    --backup=BACKUP

For the full list of options, refer to the gcloud beta container backup-restore volume-backups describe documentation.

Update a backup

You might want to edit the information about a backup, for example its description or labels. Changing the description or labels does not impact how the backup is handled.

You might also want to modify the retention policy for the backup, for example how long to retain the backup, or the period of time during which backups cannot be deleted. You can only increase retention policy parameters.

Update a backup by using the gcloud CLI or the Google Cloud console.

gcloud

To update a backup, for example by adding a new description, run the following command:

gcloud beta container backup-restore backups update BACKUP\
    --project=PROJECT_ID \
    --location=LOCATION \
    --backup-plan=BACKUP_PLAN \
    --description=DESCRIPTION

For the full list of options, refer to the gcloud beta container backup-restore backups update documentation.

Console

Perform the following tasks in the Google Cloud console:

Go to the Google Kubernetes Engine page in the Google Cloud console.

Go to Google Kubernetes Engine
In the navigation menu, click Backup for GKE.
Click the Backups tab.
Expand the backup plan and click the backup name.
Click Edit to edit a backup section and click Save changes.

Delete a backup

Backups can be deleted in two ways:

If the backup plan defines a retention period, backups created for that plan are automatically deleted after that period expires.
You can manually delete the backup.

If the backup plan for this backup defines a minimum lifetime for backups, configured with the --backup-delete-lock-days flag, then backups created for this plan cannot be deleted (either automatically or manually) until that lifetime expires.

You can manually delete a backup by using the gcloud CLI or the Google Cloud console.

gcloud

To delete a backup, run the following command:

gcloud beta container backup-restore backups delete BACKUP \
    --project=PROJECT_ID \
    --location=LOCATION \
    --backup-plan=BACKUP_PLAN

For the full list of options, refer to the gcloud beta container backup-restore backups delete documentation.

Console

Perform the following tasks in the Google Cloud console:

Go to the Google Kubernetes Engine page in the Google Cloud console.

Go to Google Kubernetes Engine
In the navigation menu, click Backup for GKE.
Click the Backups tab.
Expand the plan and click the backup name.
Click Delete backup.
Type the backup plan name and then click Delete backup in the confirmation dialog.
