|

|
||||
A snapshot repository must be registered before you can perform
|
||||
<<snapshot-restore,snapshot and restore>> operations. You can use the put
|
||||
snapshot repository API to register new repositories and update existing ones.
|
||||
See <<snapshots-register-repository>>.
|
||||
|
||||
TIP: Because snapshot formats can change between major versions of
|
||||
{es}, we recommend registering a new snapshot repository for each major version.
|
||||
See <<snapshot-restore-version-compatibility>>.

`master_timeout`::
|
||||
(Optional, <<time-units, time units>>) Specifies the period of time to wait for
|
||||
a connection to the master node. If no response is received before the timeout
|
||||
expires, the request fails and returns an error. Defaults to `30s`.
|
||||

|
||||
IMPORTANT: You can also specify this value using the `master_timeout` request
|
||||
body parameter. If both parameters are specified, only the query parameter is
|
||||
used.
|
||||
|
||||
`timeout`::
|

(Optional, <<time-units, time units>>) Specifies the period of time to wait for

a response. If no response is received before the timeout expires, the request

fails and returns an error. Defaults to `30s`.

parameter. If both parameters are specified, only the query parameter is used.
|

|

`verify`::
|
||||
(Optional, boolean)
|

If `true`, the request verifies the repository is functional on all master and

data nodes in the cluster. If `false`, this verification is skipped. Defaults to

`true`.

|

====
|

`fs`::
|
||||
Shared file system repository. Repositories of this type use a shared file
|
||||
system to store snapshots. This file system must accessible to all master and
|
||||
data nodes in the cluster.
|
||||
+
|
||||
IMPORTANT: To register a shared file system repository, you must mount the same
|
||||
shared filesystem to the same location on all master and data nodes. This
|
||||
location must be registered in the `path.repo` setting on all master and data
|
||||
nodes in the cluster.
|
||||
+
|
||||
See <<snapshots-filesystem-repository>>.
|
||||
|
||||
[xpack]#`source`#::
|
||||
Source-only repository. You can use source-only repositories to create minimal,
|
||||
source-only snapshots that take up to 50% less space on disk.
|
||||
+
|
||||
Source-only snapshots are only supported if the <<mapping-source-field,`_source`
|
||||
field>> is enabled and no
|
||||
<<request-body-search-source-filtering,source-filtering>> is applied.
|
||||
+
|
||||
WARNING: Source-only snapshots contain stored fields and index metadata. They do
|
||||
not include index or doc values structures and are not searchable when restored.
|
||||
After restoring a source-only snapshot, you must <<docs-reindex,reindex>> the
|
||||
data into a new index.
|
||||
+
|
||||
See <<snapshots-source-only-repository>>.
|
||||
|
||||
`url`::
|
||||
URL repository. Repositories of this type are read-only
|
||||
for the cluster. This means the cluster can retrieve or restore snapshots from
|
||||
the repository but cannot write or create snapshots in it.
|
||||
+
|
||||
You can use URL repositories as an alternative way to give a cluster read-only
|
||||
access to a shared file system (`fs`) repository.
|
||||
+
|
||||
See <<snapshots-read-only-repository>>.

More repository types are available through these official

plugins:

====
|
||||
`chunk_size`::
|
||||
(Optional, <<byte-units,byte value>>)
|
||||
Maximum size of files in snapshots. In snapshots, files larger than this are
|
||||
broken down into chunks of this size or smaller. Defaults to `null` (unlimited
|
||||
file size).
|
||||
|
||||
`compress`::
|
||||
(Optional, boolean)
|
||||
If `true`, metadata files, such as index mappings and settings, are compressed
|
||||
in snapshots. Data files are not compressed. Defaults to `true`.
|
||||
|
||||
`location`::
|
||||
(Required, string)
|
||||
Location of the shared filesystem used to store and retrieve snapshots. This
|
||||
location must be registered in the `path.repo` setting on all master and data
|
||||
nodes in the cluster.
|
||||
|
||||
`max_restore_bytes_per_sec`::
|
||||
(Optional, <<byte-units,byte value>>)
|
||||
Maximum snapshot restore rate per node. Defaults to `40mb` per second.
|
||||
|
||||
`max_snapshot_bytes_per_sec`::
|
||||
(Optional, <<byte-units,byte value>>)
|
||||
Maximum snapshot creation rate per node. Defaults to `40mb` per second.
|
||||
|
||||
`readonly`::
|
||||
(Optional, boolean)
|
||||
If `true`, the repository is read-only. The cluster can retrieve and restore
|
||||
snapshots from the repository but not write to the repository or create
|
||||
snapshots in it.
|
||||
+
|
||||
If `false`, the cluster can write to the repository and create snapshots in it.
|
||||
Defaults to `false`.

|
||||
[TIP]
|
||||
=====
|
||||
If you register the same snapshot repository with multiple clusters, only
|
||||
one cluster should have write access to the repository. Having multiple clusters
|
||||
write to the repository at the same time risks corrupting the contents of the
|
||||
repository.
|
||||
|
||||
Only a cluster with write access can create snapshots in the repository. All
|
||||
other clusters connected to the repository should have the `readonly` parameter
|
||||
set to `true`. This means those clusters can retrieve or restore snapshots from
|
||||
the repository but not create snapshots in it.

Delegated repository type. For valid values, see the

`url`::
|

(Required, string)
|
||||
URL location of the root of the shared filesystem repository. The following
|

protocols are supported:

|
||||
* `file`
|

* `ftp`
|
||||
* `http`
|
||||
* `https`
|
||||
* `jar`
|
||||
|
||||
URLs using the `file` protocol must point to the location of a shared filesystem
|
||||
accessible to all master and data nodes in the cluster. This location must be
|
||||
registered in the `path.repo` setting.
|
||||
|
||||
URLs using the `http`, `https`, or `ftp` protocols must be whitelisted in the
|
||||
`repositories.url.allowed_urls` setting. This setting supports wildcards in the
|
||||
place of a host, path, query, or fragment in the URL.
