backup using RMAN
Posted on 2015-02-04
right now try to use RMAN to backup a database. usually we are expecte to do a level 0 full backup on sunday and then do level 1 backup daily.
but I see there are more than one type of level 1 backup:
1) cumulative level 1
2) differential level 1
any other diff type ? what is the diff between them and what is the command to execute it?
