The SHOW BACKUP statement lists the contents of a backup created with the BACKUP statement.
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 notIMPLICIT) credentials. Azure is alwaysSPECIFIEDby default. - Userfile
The source file URL does require the admin role in the following scenarios:
- S3 or GS using
IMPLICITcredentials - Use of a custom endpoint on S3
- Nodelocal
We recommend using cloud storage for bulk operations.
Synopsis
Parameters
| Parameter | Description |
|---|---|
SHOW BACKUPS IN location |
List the backup paths in the given location. See the example. |
SHOW BACKUP location |
Show the details of the backup in the given location. See the example. |
SHOW BACKUP LATEST IN location |
Show the most recent backup added in the given location. See the example. |
SHOW BACKUP SCHEMAS location |
Show the schema details of the backup in the given location. See the example. |
SHOW BACKUP subdirectory IN location |
List the full and incremental backups that are stored in the given full backup's subdirectory within a location. 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 | New in v21.2: Display descriptor IDs of every object in the backup, including the object's database and parent schema. |
as_json |
N/A | New in v21.2: Display the backup's internal metadata as JSON in the response. |
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 |
New in v21.2: 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 location 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.
Example
Show a backup
> SHOW BACKUP 's3://test/backup-test?AWS_ACCESS_KEY_ID=[placeholder]&AWS_SECRET_ACCESS_KEY=[placeholder]';

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 location. To view details for a backup created by a schedule, you can use the following:
SHOW BACKUPS IN ystatement to view a list of the available full backup subdirectories.SHOW BACKUP x IN ystatement to view a list of the full and incremental backups that are stored in a specific full backup's subdirectory.
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:
> SHOW BACKUP 's3://test/backup-test?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:
> SHOW BACKUP '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®ION=us-east-1';

Show a backup with descriptor IDs
New in v21.2:
Use WITH debug_ids to display the descriptor IDs related to each object in the backup:
SHOW BACKUP '/2021/11/15-150703.21' IN 's3://test/backup-test?AWS_ACCESS_KEY_ID=[placeholder]&AWS_SECRET_ACCESS_KEY=[placeholder]' WITH debug_ids;

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:
SHOW BACKUP '/2021/11/15-150703.21' IN 's3://test/backup-test?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 ... 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:
SELECT jsonb_pretty(manifest->'entryCounts') AS f FROM [SHOW BACKUP '/2021/11/15-150703.21' IN 's3://test/backup-test?AWS_ACCESS_KEY_ID=[placeholder]&AWS_SECRET_ACCESS_KEY=[placeholder]' with as_json];
{
"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:
SELECT f->>'path' FROM (SELECT jsonb_array_elements(manifest->'files') AS f FROM [SHOW BACKUP '/2021/11/15-150703.21' IN 's3://test/backup-test?AWS_ACCESS_KEY_ID=[placeholder]&AWS_SECRET_ACCESS_KEY=[placeholder]' WITH as_json]);
