NAME
    gcloud spanner backups get-iam-policy - get the IAM policy for a Cloud
        Spanner backup

SYNOPSIS
    gcloud spanner backups get-iam-policy (BACKUP : --instance=INSTANCE)
        [--filter=EXPRESSION] [--limit=LIMIT] [--page-size=PAGE_SIZE]
        [--sort-by=[FIELD,...]] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    gcloud spanner backups get-iam-policy displays the IAM policy associated
    with a Cloud Spanner database. If formatted as JSON, the output can be
    edited and used as a policy file for set-iam-policy. The output includes an
    "etag" field identifying the version emitted and allowing detection of
    concurrent policy updates; see $ {parent} set-iam-policy for additional
    details.

EXAMPLES
    To print the IAM policy for a given Cloud Spanner backup, run:

        $ gcloud spanner backups get-iam-policy example-backup \
            --instance=example-instance

POSITIONAL ARGUMENTS
     Backup resource - The Cloud Spanner backup for which to display the IAM
     policy. The arguments in this group can be used to specify the attributes
     of this resource. (NOTE) Some attributes are not given arguments in this
     group but can be set in other ways. To set the project attribute:
      ◆ provide the argument backup on the command line with a fully
        specified name;
      ◆ set the property core/project;
      ◆ provide the argument --project on the command line.

     This must be specified.

       BACKUP
          ID of the backup or fully qualified identifier for the backup. To set
          the backup attribute:
          ▸ provide the argument backup on the command line.

          This positional argument must be specified if any of the other
          arguments in this group are specified.

       --instance=INSTANCE
          The name of the Cloud Spanner instance.

          To set the instance attribute:
          ▸ provide the argument backup on the command line with a fully
            specified name;
          ▸ provide the argument --instance on the command line;
          ▸ set the property spanner/instance.

LIST COMMAND FLAGS
     --filter=EXPRESSION
        Apply a Boolean filter EXPRESSION to each resource item to be listed.
        If the expression evaluates True, then that item is listed. For more
        details and examples of filter expressions, run $ gcloud topic filters.
        This flag interacts with other flags that are applied in this order:
        --flatten, --sort-by, --filter, --limit.

     --limit=LIMIT
        Maximum number of resources to list. The default is unlimited. This
        flag interacts with other flags that are applied in this order:
        --flatten, --sort-by, --filter, --limit.

     --page-size=PAGE_SIZE
        Some services group resource list output into pages. This flag
        specifies the maximum number of resources per page. The default is
        determined by the service if it supports paging, otherwise it is
        unlimited (no paging). Paging may be applied before or after --filter
        and --limit depending on the service.

     --sort-by=[FIELD,...]
        Comma-separated list of resource field key names to sort by. The
        default order is ascending. Prefix a field with ``~'' for descending
        order on that field. This flag interacts with other flags that are
        applied in this order: --flatten, --sort-by, --filter, --limit.

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.
