As I am looking into upgrading from our current 11g instance to 12c I am also looking at the differences (if any) of the backup strategies.
If i understand the documentation correctly, it looks like in 11g entire directories were backed up, then a few specific files
Introducing Backup and Recovery - 11g Release 1 (11.1.1)
Now looking at the 12c documentation it looks like its a handful of entire directories and specific files
https://docs.oracle.com/middleware/1221/core/ASADM/br_bkp.htm#ASADM11686
So the folders for ORACLE_HOME, orainventory need to be to be backed up entirely? And then specific files oraInst.loc, oratab for example.
Then the RPD, catalog and security can be backed up using BAR files I believe to allow migration between enviroments.
I just wanted to make sure, am I understanding all this correctly?
12c seems to have quite a few less directories compared to 11g.
Im not a system administrator by trade, and am just starting to dabble into the admin side of things, so just wanted to make sure Im on the right track.
