查询自动创建快照的策略
功能介绍
CSS服务的快照备份功能为Elasticsearch集群提供数据保护和恢复能力。通过快照备份,可以将集群的数据状态保存到OBS桶中,以便在需要时进行恢复。集群快照分为两种方式:自动创建快照和手动创建快照。该接口用于查询自动创建快照策略。
-
自动创建快照:按照预设的时间策略自动执行快照备份操作,适合定期备份场景,例如每日或每周备份,以确保数据的持续保护。通过设置自动快照策略,用户可以减少手动操作,提高备份的可靠性和效率。
-
手动创建快照:用户根据需求手动触发快照备份操作,适合临时备份或特定场景,如在进行重大操作前(如集群升级)进行备份,以便在出现问题时能够快速恢复到之前的状态。手动快照提供了更高的灵活性,用户可以根据实际需求随时创建快照。
