We have multiple clients where for some clients will take daily application backup for some clients monthly once . Its depends on changes occurring in your file system (rdf, fmb, oaf deploy ments etc)
If you want proper cold backup
1. Pre clone on db and apps
2.Stop application/db services
3. take os tar backup of Oracle Home binaries, datafiles and application file system
Supposing the client operates 24x7 and can not afford downtime, how to perform a proper hot backup?
In this case you need to go with RMAN.
Oracle Binaries & application file system while services up & running you can take tar.
Assuming that we have RMAN backup daily.
How often do we need to take tar backup of Oracle binaries and apps file system?
Is it weekly, monthly, or once a year?
is to backup appstier/webtier after patch has been applied. (you can create a tar file and keep it on a different mount point). These tar files can be used for cloning another environment.
Database: Rman - daily.
