CREATE BACKUP CONFIGURATION
Creates a new backup configuration for a keyspace.
The keyspace can be backed up to one or more backup stores, and the frequency at which the backup should be run can be specified.
If enabled
is set to false, the backup will only run when manually triggered, and frequency
is ignored.
Backup configurations are subject to the following restrictions:
-
Backup configurations can only target a single keyspace. Specific tables cannot be backed up.
-
Only one configuration targeting the same keyspace and backup store can exist.
-
Configurations that target the same keyspace in different backup stores are allowed.
Synopsis
CREATE BACKUP CONFIGURATION <configuration_name>
OF <keyspace_name>
TO STORE <store_name> [, <store_name_2>, <store_name_N>, ... ]
WITH frequency = <frequency>
AND enabled = (true | false) ;

- configuration_name
-
The backup configuration name. Configuration names can use alphanumeric characters and underscores only. They are case insensitive.
- keyspace_name
-
Name of the keyspace to backup.
- 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.
Examples
Create an automatic backup configuration
Create an automatic backup configuration that runs daily at midnight on two separate stores:
CREATE BACKUP CONFIGURATION daily_backup_config
OF keyspace_1
TO STORE local_store_1, s3_store_1
WITH frequency = '0 0 * * *'
AND enabled = true;
Create a manual backup configuration
Create a backup that can be run manually on a single store:
CREATE BACKUP CONFIGURATION daily_backup_config
OF keyspace_2
TO STORE local_store_1
WITH frequency = '* * * * *'
AND enabled = false;
