The word backup is reserved by IT operations with a dedicated process.
That process is often related to BCM (business continuity management).

Using that word backup in a SAS dedicated approach is very confusing as those involved IT-architect are reacting on the words not on the functionality.

Reading the SAS instructions it is even getting more confusing.:
" To back up the SAS installation directory, you can use operating system commands or third-party tools.
CAUTION:
When restoring backups that were created with operating system commands or third-party tools, you must preserve the original datetime stamps on the files. "

This again is sometimes violated by those standard backup processes.
