I'm implementing incremental backup in my database. As per my knowledge after level 0 backup, level 1 backup will take only the backups of changes that are done. But in my db after level 0 full backup, level 1 backup is also taking the almost same backup size of level 0.
On Friday, level 0 backup. Backup Size: 49.8 GB
BACKUP INCREMENTAL LEVEL 0 DATABASE PLUS ARCHIVELOG;
On Saturday, level 1 backup. Backup Size: 45.2 GB
BACKUP INCREMENTAL LEVEL 1 DATABASE PLUS ARCHIVELOG;
Is there any mistake which I have done here in the RMAN command. Please help.....
