A complete file system backup includes an entire system directory. For example, backing up the EPM Oracle home directory backs up all installed EPM System products. You can also perform file-system backups of these types and frequencies:
Post-installation—Directories created or modified if you reconfigure products
Daily incremental—New directories or files or those modified since the previous day (including repository content and log files)
Weekly full—All files in the directories for which you perform daily incremental backups
As needed—Data that is modified infrequently
