NAME
    gcloud beta compute target-pools set-backup - set a backup pool for a
        target pool

SYNOPSIS
    gcloud beta compute target-pools set-backup NAME
        (--backup-pool=BACKUP_POOL | --no-backup-pool)
        [--failover-ratio=FAILOVER_RATIO] [--region=REGION]
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (BETA) gcloud beta compute target-pools set-backup is used to set a backup
    target pool for a primary target pool, which defines the fallback behavior
    of the primary pool. If the ratio of the healthy instances in the primary
    pool is at or below the specified --failover-ratio value, then traffic
    arriving at the load-balanced IP address will be directed to the backup
    pool.

EXAMPLES
    To cause TARGET-POOL (in region us-central1) to fail over to BACKUP-POOL
    when more than half of the TARGET-POOL instances are unhealthy, run:

        $ gcloud beta compute target-pools set-backup TARGET-POOL \
            --backup-pool=BACKUP-POOL --failover-ratio=0.5 \
            --region=us-central1

    To remove BACKUP-POOL as a backup to TARGET-POOL, run:

        $ gcloud beta compute target-pools set-backup TARGET-POOL \
            --backup-pool='' --region=us-central1

POSITIONAL ARGUMENTS
     NAME
        The name of the target pool for which to set the backup pool.

REQUIRED FLAGS
     Exactly one of these must be specified:

       --backup-pool=BACKUP_POOL
          Name of the target pool that will serve as backup.

       --no-backup-pool
          Unsets the backup pool. This disables failover.

OPTIONAL FLAGS
     --failover-ratio=FAILOVER_RATIO
        The new failover ratio value for the target pool. This must be a float
        in the range of [0, 1].

     --region=REGION
        Region of the target pool to set a backup pool for. If not specified,
        you might be prompted to select a region (interactive mode only).

        To avoid prompting when this flag is omitted, you can set the
        compute/region property:

            $ gcloud config set compute/region REGION

        A list of regions can be fetched by running:

            $ gcloud compute regions list

        To unset the property, run:

            $ gcloud config unset compute/region

        Alternatively, the region can be stored in the environment variable
        CLOUDSDK_COMPUTE_REGION.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.

    Run $ gcloud help for details.
