Objects: bulkRestore

Initiates a long-running operation to bulk restore multiple soft-deleted objects in a bucket. Soft-deleted objects that meet the criteria defined in the request body parameters are restored to the bucket.

When a soft-deleted object is restored, a new copy of that object is created in the same bucket and inherits the same metadata as the soft-deleted object. The inherited metadata is the metadata that existed when the original object became soft deleted, with the following exceptions:

  • The createTime of the new object is set to the time at which the soft-deleted object was restored.
  • The softDeleteTime and hardDeleteTime values are cleared.
  • A new generation is assigned and the metageneration is reset to 1.
  • If the soft-deleted object was in a bucket that had Autoclass enabled, the new object is restored to Standard storage.

If a live object using the same name already exists in the bucket and becomes overwritten, the live object becomes a noncurrent object if Object Versioning is enabled on the bucket. If Object Versioning is not enabled, the live object becomes soft deleted.

The specified bucket must have a soft delete policy. Otherwise, the request fails with a 412 Failed Precondition error with the reason softDeletePolicyNotSet.

Required permissions

The authenticated user must have the following IAM permissions to use this method:

  • storage.buckets.restore
  • storage.objects.restore
  • storage.objects.create
  • storage.objects.getIamPolicy (only required if projection is true and the relevant bucket has uniform bucket-level access disabled)
  • storage.objects.setIamPolicy (only required if copySourceAcl is true and the relevant bucket has uniform bucket-level access disabled)

Request

HTTP request

POST https://storage.googleapis.com/storage/v1/b/bucket/o/bulkRestore

In addition to standard query parameters, the following query parameters apply to this method.

Parameters

Parameter name Value Description
Path parameters
bucket string Name of the bucket in which objects will be restored.

Request body

In the request body, supply a data structure with the following properties:

Property name Value Description Notes
allowOverwrite boolean

If false (default), the bulk restore operation will not overwrite live objects that have the same name as the soft-deleted objects to be restored. This means that some soft-deleted objects might not get restored.

If true, live objects that have the same name as the soft-deleted objects will be overwritten. If Object Versioning is enabled on the bucket, the live objects will become noncurrent when overwritten. If Object Versioning is not enabled, the live object will become soft-deleted when overwritten. Noncurrent objects that have the same name as the soft-deleted objects to be restored do not get overwritten.

 writable
matchGlob string Restores only the soft-deleted objects that match the specified glob. If this parameter is not specified, all soft-deleted objects that match the specified time range are restored. For more information about glob syntax, see the match glob documentation. writable
softDeletedAfterTime string

Restores only the soft-deleted objects that were soft deleted after the specified time.

 writable
softDeletedBeforeTime string Restores only the soft-deleted objects that were soft deleted before the specified time. writable
copySourceAcl boolean Applicable only for buckets the don't have uniform bucket-level access enabled. If true, copies the soft-deleted object's ACL and applies it to the restored object. If false or not specified, the restored object inherits the bucket's default object ACL. writable

Response

If successful, this method returns an instance of operation in the response body:

{
  "name": "string",
  "metadata": { object (BulkRestoreObjectsMetadata)},
  "done": "boolean",
  // Union field result can be only one of the following:
  "error": { object (Status)},
  "response": {}
  // End of list of possible types for union field result
}
Property name Value Description Notes
name string The server-assigned name of the operation.
metadata object

An object of type BulkRestoreObjectsMetadata:

{
  "allowOverwrite": boolean,
  "matchGlobs": "string",
  "deleteAfterTime": "datetime",
  "deleteBeforeTime": "datetime",
  "copySourceAcl": boolean,
  "succeededCount": "long",
  "skippedCount": "long",
  "failedCount": "long",
}

Where:

  • succeededCount is the number of successfully restored objects.
  • skippedCount is the number of objects skipped as a result of the specified deletedAfterTime, deletedBeforeTime, and matchGlobs parameters. If multiple generations of an object match the criteria, only the latest generation is restored and the rest are skipped.
  • failedCount is the number of objects that failed to be restored. Objects can fail to be restored if, for example, a live object with the same name cannot be rewritten.

done boolean If false, indicates that the operation is still in progress, and neither error nor response is set. If true, the operation is completed and either error or response is set.
error object Indicates that the operation is considered to be successful, unless it failed to start because of invalid parameters, or because of an access denied error. For information about status and error codes returned by this API, see the reference page.
response object Empty. Detailed error information can be obtained from Cloud Audit Logs.
