Dear Dojo
At one customer we have very small installation with only a few devices.
We are not interested in historical alarm details, but we are facing a cassandra backup of almost 10GB.
A deeper investigation shows a cassandra directory of almost 7 GB:
A DataMiner backup take a lot of time and we would like to shrink the database to the really needed alarms.
Can you explain, what is stored in timetrace, and how to delete old, not nessecary entries?
I appreciate your support.

Hi Joerg,
The timetrace table stores historical alarms : DataMiner general database – NoSQL Database – Cassandra | DataMiner Docs.
If you do not need historical alarms, you can truncate this table – TRUNCATE | CQL for Cassandra 3.0 (datastax.com).
