Hidirectly with a select in an transactions also handling the active data.
We have a database nearly 3 TByte big where most of the data (80%) is stored in tablespaces which hold "archival data". This archival data is just reorganized every at the beginning to hold data of the last year. The data is still used in joins or
Because the tables and indexes in this "archive" tablespaces is reorganized and read only and will never change again, I thought it would be good to backup this tablespaces only once in the year and for the other tablespaces I make a weekly onlinetablespace backup including logs and on the other days incremental online backup.
I have simulated that for a system crash and for restoring some tablespaces into a different instance to get data back which could be destroyed of human errors etc..[test detail snipped]
My question now is if I have also to save the archived logs regularly since the backups of the large archived tablespaces were performed?
