SHOW BACKUP

The SHOW BACKUP statement lists the contents of a backup created with the BACKUP statement.

Warning:

The SHOW BACKUP syntax without the IN keyword is deprecated as of v22.1 and will be removed in a future release.

We recommend using SHOW BACKUP FROM {subdirectory} IN {collectionURI} to view backups in a subdirectory at a collection's URI.

For guidance on the syntax for SHOW BACKUP FROM, see the examples.

Required privileges

SHOW BACKUP requires read permissions to its target destination.

The source file URL does not require the admin role in the following scenarios:

  • S3 and GS using SPECIFIED (and not IMPLICIT) credentials. Azure is always SPECIFIED by default.
  • Userfile

The source file URL does require the admin role in the following scenarios:

We recommend using cloud storage for bulk operations.

Synopsis

SHOW BACKUPS IN location BACKUP subdirectory IN SCHEMAS location WITH kv_option_list OPTIONS ( kv_option_list )

Parameters

Parameter Description
SHOW BACKUPS IN collectionURI List the backup paths in the given collection URI. See the example.
SHOW BACKUP FROM subdirectory IN collectionURI Show the details of backups in the subdirectory at the given collection URI. Also, use FROM LATEST in collectionURI to show the most recent backup. See the example.
SHOW BACKUP SCHEMAS FROM subdirectory IN collectionURI Show the schema details of the backup in the given collection URI. See the example.
kv_option_list Control the behavior of SHOW BACKUP with a comma-separated list of these options.

Options

Option Value Description
privileges N/A List which users and roles had which privileges on each table in the backup. Displays original ownership of the backup.
encryption_passphrase STRING The passphrase used to encrypt the files that the BACKUP statement generates (the data files and its manifest, containing the backup's metadata).
debug_ids N/A Display descriptor IDs of every object in the backup, including the object's database and parent schema.
as_json N/A Display the backup's internal metadata as JSON in the response.
incremental_location STRING List the details of an incremental backup taken with the incremental_location option.

Response

The following fields are returned:

Field Description
database_name The database name.
parent_schema_name The name of the parent schema.
object_name The name of the database, table, type, or schema.
object_type The type of object: database, table, type, or schema.
backup_type The type of backup: full or incremental.
start_time The time of the earliest data encapsulated in the backup. Note that this only displays for incremental backups. For a full backup, this is NULL.
end_time The time to which data can be restored. This is equivalent to the AS OF SYSTEM TIME of the backup. If the backup was not taken with revision history, the end_time is the only time the data can be restored to. If the backup was taken with revision history, the end_time is the latest time the data can be restored to.
size_bytes The size of the backup, in bytes.
rows Number of rows in tables that are part of the backup.
create_statement The CREATE statement used to create table(s), view(s), or sequence(s) that are stored within the backup. This displays when SHOW BACKUP SCHEMAS is used. Note that tables with references to foreign keys will only display foreign key constraints if the table to which the constraint relates to is also included in the backup.
is_full_cluster Whether the backup is of a full cluster or not.
path The list of the full backup's subdirectories. This field is returned for SHOW BACKUPS IN collectionURI only. The path format is <year>/<month>/<day>-<timestamp>.

See Show a backup with descriptor IDs for the responses displayed when the WITH debug_ids option is specified.

Examples

View a list of the available full backup subdirectories

To view a list of the available full backups subdirectories, use the following command:

icon/buttons/copy
> SHOW BACKUPS IN 's3://{bucket name}/{path}?AWS_ACCESS_KEY_ID={placeholder}&AWS_SECRET_ACCESS_KEY={placeholder}';
        path
-------------------------
/2022/04/13-202334.48
/2022/04/13-202413.70
(2 rows)

The path format is <year>/<month>/<day>-<timestamp>.

Show the most recent backup

New in v22.1: To view the most recent backup, use the LATEST syntax:

icon/buttons/copy
> SHOW BACKUP FROM LATEST IN 's3://{bucket name}?AWS_ACCESS_KEY_ID={placeholder}&AWS_SECRET_ACCESS_KEY={placeholder}';

Show a backup taken with the incremental location option

New in v22.1: To view an incremental backup that was taken with the incremental_location option, run SHOW BACKUP with the full backup and incremental backup location following the original BACKUP statement.

You can use the option to show the most recent backup where incremental_location has stored the backup:

icon/buttons/copy
SHOW BACKUP FROM LATEST IN {'full backup collectionURI'} WITH incremental_location = {'incremental backup collectionURI'};

You will receive an error if there is a collection of backups in the storage location that you pass to SHOW BACKUP. It is necessary to run SHOW BACKUP with the specific backup directory rather than the backup collection's top-level directory. Use SHOW BACKUPS IN with your storage location to list the backup directories it contains, which can then be run with SHOW BACKUP to inspect the metadata.

Show details for scheduled backups

When a backup is created by a schedule, it is stored within a collection of backups in the given collection URI. To view details for a backup created by a schedule, you can use the following:

Show an encrypted backup

Depending on how the backup was encrypted, use the encryption_passphrase option and the same passphrase that was used to create the backup:

icon/buttons/copy
> SHOW BACKUP FROM '2020/09/24-190540.54' IN 's3://{bucket name}?AWS_ACCESS_KEY_ID={placeholder}&AWS_SECRET_ACCESS_KEY={placeholder}'
      WITH encryption_passphrase = 'password123';

Or, use the kms option and the same KMS URI that was used to create the backup:

icon/buttons/copy
> SHOW BACKUP FROM '2020/09/24-190540.54' IN 's3://test/backups/test_explicit_kms?AWS_ACCESS_KEY_ID=123&AWS_SECRET_ACCESS_KEY=123'
      WITH kms = 'aws:///arn:aws:kms:us-east-1:123456789:key/1234-abcd-5678-efgh-90ij?AWS_ACCESS_KEY_ID=123456&AWS_SECRET_ACCESS_KEY=123456&REGION=us-east-1';

Show a backup's internal metadata

Use the WITH as_json option to output a backup's internal metadata, contained in its manifest file, as a JSON value:

icon/buttons/copy
SHOW BACKUP FROM '/2021/11/15-150703.21' IN 's3://{bucket name}?AWS_ACCESS_KEY_ID={placeholder}&AWS_SECRET_ACCESS_KEY={placeholder}' WITH as_json;

The response will include a manifest column with the file's contents as the JSON value. Use JSONB functions to query particular data or edit the format of the response.

Note:

The response returned from SHOW BACKUP FROM ... WITH as_json is a backup's internal metadata. This content is subject to change from version to version of CockroachDB and does not offer the same stability guarantees as the other SHOW BACKUP options and their responses. As a result, as_json should only be used for debugging or general inspection purposes.

For example, to return a specific entry from the JSON response as a string indented and with newlines use the jsonb_pretty() function:

icon/buttons/copy
WITH x AS (SHOW BACKUP FROM '/2021/11/15-150703.21' IN 's3://{bucket name}?AWS_ACCESS_KEY_ID={placeholder}&AWS_SECRET_ACCESS_KEY={placeholder}' with as_json) SELECT jsonb_pretty(manifest->'entryCounts') AS f FROM x;
  {
      "dataSize": "458371",
      "indexEntries": "1015",
      "rows": "2565"
  }

To query for particular data, use the jsonb_array_elements() function to expand the desired elements from the JSON response. The following query returns the paths to each of the data files within the backup:

icon/buttons/copy
WITH x AS (SHOW BACKUP FROM '/2021/11/15-150703.21' IN 's3://{bucket name}?AWS_ACCESS_KEY_ID={placeholder}&AWS_SECRET_ACCESS_KEY={placeholder}' WITH as_json) SELECT f->>'path' FROM (SELECT jsonb_array_elements(manifest->'files') AS f FROM x);
