CLEAN BACKUPS

Removes stale backups based upon backup retention policy and an optional backup configuration name and store name.

The DSE Backup Service runs a scheduled task every two hours to get rid of backups for all configurations and stores based upon the configured retention policy. All backup files are removed, including metadata and SSTables. The CLEAN BACKUPS statement lets you run the cleaning process manually if desired. For details on configuring backup retention policies, see Customize backup retention policy.

During the cleaning process, backups that are in the process of being deleted will show in the LIST BACKUP STORES output with the status CLEANING until the cleaning is complete.

Syntax conventions Description

Syntax conventions	Description
UPPERCASE	Literal keyword, unless bold. If bold, it is a variable. For example, `DESCRIBE KEYSPACE KEYSPACE_NAME;` includes the CQL keywords `DESCRIBE KEYSPACE` and the variable `KEYSPACE_NAME`. If you ran this command, you would replace `KEYSPACE_NAME` with the name of the keyspace you want to describe, such as `DESCRIBE KEYSPACE customers;`.
Lowercase	Not literal
`< >` or bold	Often represents a variable placeholder that you must replace with a user-defined value. However, angle brackets are also required to surround data types in a set, list, map, or tuple.
`[]`	Optional command arguments. Do not type the square brackets.
`( )`	A group of options you can choose from. Do not type the parentheses.
`\|`	Separates alternative elements when you can choose one of several elements. Type any one of the elements. Do not type the vertical bar.
`...`	A repeatable syntax element. Can be reused as often as required.
`'`	Single quotation marks must surround literal strings in CQL statements, such as `'example_string'`. Use single quotation marks to preserve upper case. Additionally, single quotation marks are used in Search CQL to surround an entire XML schema declaration. For example: `' <schema> ... </schema> '`
`{ <key> : <value> }`	Curly braces enclose map collections or key value pairs. A colon separates the key and the value.
`<datatype2`	Angle brackets enclose data types in a set, list, map, or tuple. Separate the data types with a comma.
`;`	Marks the end of a CQL statement.
`[--]`	Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options.
`@<xml_entity>='<xml_entity_type>'`	Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrConfig files.

{ <key> : <value> }

Curly braces enclose map collections or key value pairs. A colon separates the key and the value.

<datatype2

Angle brackets enclose data types in a set, list, map, or tuple. Separate the data types with a comma.

[--]

Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options.

@<xml_entity>='<xml_entity_type>'

Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrConfig files.

configuration_name: The backup configuration name. Configuration names can use alphanumeric characters and underscores only. They are case insensitive.
