Abstract
A data protection system configured to backup a time series database is provided. The data protection system may be integrated with or have access to consolidation policies of the time series database. The backup policy and backup retention policy are set by monitoring the consolidation policy and adjusting the backup policy to ensure that the data in the time series database is protected prior to being downscaled, discarded or otherwise consolidated.
Claims20
A computer-implemented method for backing up a time series database, the method comprising:
- monitoring, by a data protection system that includes one or more processors, a consolidation policy of the time series database, wherein consolidation policy includes consolidation data that identifies when data in the time series database is downscaled, the data including time series data, wherein the data in the time series database loses resolution when the data is downscaled;
- defining, by the one or more processors, a backup policy of the data protection system based on the consolidation policy of the time series database;
- generating, by the one or more processors, backups of the data in the time series database in accordance with the backup policy by the data protection system, wherein the backup policy ensures that the backups are generated before the data in the time series database is downscaled or discarded such that the backups contain full resolution copies of the time series data, wherein the backups further include backups of downscaled versions of the data in the time series database, wherein the downscaled versions have different resolutions of the data in the time series database;
- and
- updating, by the one or more processors, a catalog that identifies where the backups are stored and resolutions of the backups.
A non-transitory storage medium having stored therein instructions that are executable by one or more hardware processors to perform operations comprising:
- monitoring, by a data protection system that includes one or more processors, a consolidation policy of the time series database, wherein consolidation policy includes consolidation data that identifies when data in the time series database is downscaled, the data including time series data, wherein the data in the time series database loses resolution when the data is downscaled;
- defining, by the one or more processors, a backup policy of the data protection system based on the consolidation policy of the time series database;
- generating, by the one or more processors, backups of the data in the time series database in accordance with the backup policy by the data protection system, wherein the backup policy ensures that the backups are generated before the data in the time series database is downscaled or discarded such that the backups contain full resolution copies of the time series data, wherein the backups further include backups of downscaled versions of the data in the time series database, wherein the downscaled versions have different resolutions of the data in the time series database;
- and
- updating, by the one or more processors, a catalog that identifies where the backups are stored and resolutions of the backups.
