No - they'll hardlink into the snapshot folder on each data directory. They

If that is the main purpose, having "auto_snapshot: true” in cassandra.yaml

I believe SSTables are written to a temporary file then moved. If I
remember correctly, tools like tablesnap listen for the inotify event
IN_MOVED_TO. This should handle the "try to back up sstable while in

Many thanks Aaron. I will post a support issue for them. But will keep the
snapshot + incremental backups + commitlogs to recover any failure
situation.

When the server starts it reads the SSTables then applies the Commit Logs.
There is nothing you need to do other than leave the commit logs where they
are.

Hi Aaron
Thanks for the comments. Yes for the durability will keep them in a safe
place. But such crash situation, how can I restore the data (because those
are not in a SSTable and only in commit log).
Do I need to replay only that commit log when server starts after crash?
Will it override the
