amazon web services - Backup cassandra to another disk -


i'm trying backup cassandra cluster aws' s3, , found tool, seems work:
https://github.com/tbarbugli/cassandra_snapshotter/
problem is, in our current cluster, cant afford have snapshots on same disk actual data, using ssd's limited space.
i've looked nodetool snapshot documentation, didn't find option change snapshots dir.
so, how can backup cassandra disk, without using data disk?

cassandra snapshots hard links live sstables @ moment take snapshot. don't take additional space on disk. time passes new live sstables supersede old 1 @ point snapshots start count against storage space.

generally take snapshot consistent view of database @ given point in time , use external tool or script copy backup external storage (and clean snapshot).

there no additional tool provided cassandra handle copying snapshots external storage. isn't surprising backup strategies lot across companies.
