Cassandra: incremental backup #32

Closed jazzl0ver closed 6 years ago

jazzl0ver commented 6 years ago

$ cat cassandra.yaml
...
incremental_backups: false

Is it false intentionally?

JuniusLuo commented 6 years ago

The false is the default value for incremental_backups. If this is enabled, you will have to manage the flushed sstable links by yourselves. Do you have the requirements to enable it?

Below are the detail comments in cassandra.yaml, "Set to true to have Cassandra create a hard link to each sstable flushed or streamed locally in a backups/ subdirectory of the keyspace data. Removing these links is the operator's responsibility."

No, I don't. Just found out that while discovering backup tools which supports incremental backups. Thanks for explanation!

JuniusLuo commented 6 years ago

yes, we will further evaluate the backup solution. If the backup requires to enable the incremental_backups, we will enable it.
