Legend
Syntax conventions	Description
UPPERCASE	Literal keyword.
Lowercase	Not literal.
`< >`	Variable value. Replace with a user-defined value.
`[]`	Optional. Square brackets (`[]`) surround optional command arguments. Do not type the square brackets.
`( )`	Group. Parentheses ( `( )` ) identify a group to choose from. Do not type the parentheses.
`\|`	Or. A vertical bar (`\|`) separates alternative elements. Type any one of the elements. Do not type the vertical bar.
`...`	Repeatable. An ellipsis ( `...` ) indicates that you can repeat the syntax element as often as required.
`'<Literal string>'`	Single quotation (`'`) marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case.
`{ <key> : <value> }`	Map collection. Braces (`{ }`) enclose map collections or key value pairs. A colon separates the key and the value.
`<datatype2`	Set, list, map, or tuple. Angle brackets ( `< >` ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.
`<cql_statement>;`	End CQL statement. A semicolon (`;`) terminates all CQL statements.
`[--]`	Separate the command line options from the command arguments with two hyphens ( `--` ). This syntax is useful when arguments might be mistaken for command line options.
`' <<schema\> ... </schema\>> '`	Search CQL only: Single quotation marks (`'`) surround an entire XML schema declaration.
`@<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.

store_name

Name of the backup store. Store names can use alphanumeric characters and underscores only. They are case insensitive.

frequency

Standard cron timing expression defining the frequency at which the backup should be run, using Universal Time Coordinated (UTC). Cron timing expressions are five entries defined as:

MM: two digit minute, 0-60.
HH: two digit hour, 0-24.
DD: two digit day of the month, 1-31.
MM: two digit month, 1-12 (January to December).
D: single digit day of the week, 0-6 (Sunday to Saturday). Also accepts three letter day abbreviations, MON, TUE, WED, THU, FRI, SAT.

An * is a wildcard for all.

For example, run a backup on the first minute of midnight every day:

0 0 * * *

Easily generate cron timing expressions using https://crontab-generator.org/. Note that shortcuts such as */30 * * * * to run a backup every 30 minutes are not supported.
