enable BLOCK CHANGE TRACKING to speed up RMAN Level1 incremental, will next L1 incremental use it?

in Database Backup and Recovery (MOSC) 2 commentsAnswered

Hello! we are Oracle 12c/RHEL. large db, 13TB. about 500GB arch logs per day. L1 incremental took many hours to do.

hope to make it quicker by using BCT. the question is, if i enable BCT at noon, will it only keep data from this point on? and if i run L1 at midnight - will it still be forced to scan ALL db files for changes made before noon?

Another words - will BCT only give me advantage AFTER Level0 and for a first Level1?
