POST /storage/file/copy

Introduced In: 9.8

Starts a file copy operation. Only supported on flexible volumes.

Required properties

  • files_to_copy - List of files with the destination they are to be copied to.

Default property values

  • cutover_time - 10

  • hold_quiescence - false

  • max_throughput - 0

  • reference_cutover_time - 10

  • volume file copy start

Examples

Copying two files

The POST request is used to copy file(s).

# The API:
/api/storage/file/copy

# The call:
curl -X POST  "https://<mgmt-ip>/api/storage/file/copy" -H "accept: application/hal+json" -d '{"files_to_copy":[{"source":{"volume":{"name":"vol_a"},"svm":{"name":"vs0"},"path":"d1/src_f1"},"destination":{"volume":{"name":"vol_a"},"svm":{"name":"vs0"},"path":"d1/dst_f1"}}, {"source":{"volume":{"name":"vol_a"},"svm":{"name":"vs0"},"path":"d1/src_f2"},"destination":{"volume":{"name":"vol_a"},"svm":{"name":"vs0"},"path":"d1/dst_f2"}}]}'

# The response:
{
"job": {
  "uuid": "b89bc5dd-94a3-11e8-a7a3-0050568edf84",
  "_links": {
     "self": {
       "href": "/api/cluster/jobs/b89bc5dd-94a3-11e8-a7a3-0050568edf84"
     }
   }
 }
}

Parameters

Name Type In Required Description

return_timeout

integer

query

False

The number of seconds to allow the call to execute before returning. When doing a POST, PATCH, or DELETE operation on a single record, the default is 0 seconds. This means that if an asynchronous operation is started, the server immediately returns HTTP code 202 (Accepted) along with a link to the job. If a non-zero value is specified for POST, PATCH, or DELETE operations, ONTAP waits that length of time to see if the job completes so it can return something other than 202.

  • Default value: 1

  • Max value: 120

  • Min value: 0

return_records

boolean

query

False

The default is false. If set to true, the records are returned.

  • Default value:

Request Body

Name Type Description

cutover_time

integer

The maximum amount of time (in seconds) that the source can be quiesced before a destination file must be made available for read-write traffic.

files_to_copy

array[files_to_copy]

A list of source files along with the destinations they are copied to. If the terminal path component of the destination is a directory, then the source file's basename is replicated in that directory.

hold_quiescence

boolean

Specifies whether the source file should be held quiescent for the duration of the copy operation.

max_throughput

integer

Maximum amount of data, in bytes that can be transferred per second in support of this operation. A non-zero value less than 1MB/s is set to 1MB/s. A non-zero value greater than 1MB/s is truncated to the nearest integral megabyte value. If unspecified, the default value is "0" which means no range is set for the data transfer.

reference_cutover_time

integer

The maximum amount of time (in seconds) that the source reference file can be quiesced before the corresponding destination file must be made available for read-write traffic.

reference_path

string

The source reference file. If a reference file is specified, data for other files being copied will be transferred as a difference from the reference file. This can save bandwidth and destination storage if the specified source files share blocks. If provided, this input must match one of the source file paths. This input need not be provided if only one source file is specified.

The source SVM UUID or name must be provided.

7013360

The peering relationship between the two SVMs does not include application "file-copy".

7013361
