mixing Disk and TAPE devices in rman incremental backups

in Database Backup and Recovery (MOSC) 4 commentsAnswered

Hello,

suppose we have the following backup sequence (which can happen for example when a DB admin does his disk backup independently from tape device scheduled backups)

1/ level 0 backup to tape

2/ level 1 backup to tape

3/ level 0 backup to disk

4/ level 1 backup to tape

Which changes will cover step 4/ - changes since the step 2/ or since the step 3/ ? IN other words, will recovery to the point 4/ need backups 3 + 4/, or 1/,2/,4/ ?

Regards

Michal
