Restores a soft-deleted object.
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
andhardDeleteTime
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.
Required permissions
The authenticated user must have the following IAM permissions to use this method:
- storage.objects.restore
- storage.objects.create
- storage.objects.delete (only required if overwriting an existing object)
- 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)
To update object access control lists (ACLs), which only apply to objects stored in buckets with
uniform bucket-level access disabled, the
authenticated user must also have the storage.objects.setIamPolicy
permission. To
return ACLs as part of the response, the authenticated user must also have the
storage.buckets.getIamPolicy
permission.
Request
HTTP request
POST https://storage.googleapis.com/storage/v1/b/bucket/o/object/restore
In addition to standard query parameters, the following query parameters apply to this method.
To see an example of how to include query parameters in a request, see the JSON API Overview page.
Parameters
Parameter name | Value | Description |
---|---|---|
Path parameters | ||
bucket |
string |
Name of the bucket in which the new object will be created. Must be the same bucket that contained the soft-deleted object being restored. |
object |
string |
Name of the soft-deleted object to restore. For information about how to URL encode object names to be path safe, see Encoding URI path parts. |
Required query parameters | ||
generation |
long |
Specifies the version of the soft-deleted object to restore. |
Optional query parameters | ||
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.
|
ifGenerationMatch |
long |
Makes the operation conditional on there being a live version of the object with a
generation number that matches the given value. Setting ifGenerationMatch to
0 makes the operation succeed only if there is no such live object.
|
ifGenerationNotMatch |
long |
Makes the operation conditional on there being a live version of the object with a
generation number that does not match the given value. If no live object exists, the
precondition fails. Setting ifGenerationNotMatch to 0 makes the operation
succeed if there is a live version of the object.
|
ifMetagenerationMatch |
long |
Makes the operation conditional on there being a live version of the object with a metageneration number that matches the given value. |
ifMetagenerationNotMatch |
long |
Makes the operation conditional on there being a live version of the object with a metageneration number that does not match the given value. |
projection |
string |
Set of properties to return. Defaults to noAcl , unless the object resource
specifies the acl property, when it defaults to full .
Acceptable values are:
|
restoreToken |
string |
Applicable in buckets with hierarchical namespace
enabled. The restoreToken is a universally unique identifier (UUID)
associated with each soft-deleted object.
When restoring a soft-deleted object, the |
Request body
Do not supply a request body with this method.
Response
If successful, this method returns an object resource in the response body.
The following errors could occur:
- If the specified bucket in the request does not have a soft delete policy, the request fails
with a
400 Bad Request
error with the reasonSoftDeletePolicyRequired
. - If the soft-deleted object's retention duration has passed, or the soft-deleted
object no longer exists, the request fails with a
404 Not Found
error with the reasonnotFound
. - If the specified object in the request is not a soft-deleted object but is either live or
noncurrent, the request fails with a
412 Failed Precondition
error with the reasonobjectNotSoftDeleted
. - If the specified object in the request belongs to a bucket that has a
Bucket Lock retention policy, where the object's age is
less than the retention duration, the request fails with a
403 Forbidden
error with the reasonretentionPolicyNotMet
.
