本文介绍如何在Cassandra中启用并配置增量备份功能。通过设置`incremental_backups:true`，Cassandra会在每次刷新SSTable时将其保存到备份目录。结合快照使用，管理员可以在数据损坏时恢复节点。
Incremental Cassandra Backup
Enable incremental Cassandra backup
conf/cassandra.yaml
incremental_backups: trueWhen incremental backup is enabled (default is off), Cassandra persists flushed SSTable to a backup directory under
/var/lib/cassandra/data/mykeyspace/backups/
Old incremental backup files needs to be manually removed. Consider removing them after snapshots
With these incremental backup files in conjunction with a snapshot, an administrator can restore data in a node when data corruption occurs
