Hi Paul,
If I understand correctly, you are making a tar file with all the
folders named "snapshots" (i.e. the folder under which all the snapshots
are created. So you have one /snapshots /folder per table).
If this is the case, when you are executing "nodetool repair", Cassandra
will create a
Hi Paul,
I guess this might come from the incremental repairs...
The repair time is stored in the sstable (RepairedAt timestamp metadata).

Maybe your problem comes from the new role based access control in
Cassandra introduced in Cassandra 2.2.

Based on some research here and on IRC, recent versions of
Cassandra do no require anything specific when migrating to
incremental repairs but the the -inc switch even on LCS.
Any confirmation on the matter is more than welcome.
Regard

were created before you disabled compaction.

I'd be glad if someone could answer to my other questions in any case ;-).
Thanks in advance for your help

Hi,
We currently have a 3 nodes Cassandra cluster with RF = 3.
We are using Cassandra 2.1.7.
We would like to start using incremental repairs.
We have some tables using LCS compaction strategy and some others using
STCS.
Here is the procedure written in the documentation:
