Logic behind same FS for log and data backups

Hi team,

I have a doubt , when compared to traditional databases like oracle, db6 and sybase. we have a different data and log file systems.

Here in HANA why is it the same any reason or else any recomendation from SAP since its designed like this.

In many customers i have seen the backups for logs and data in the same file system , i am not sure about the logic. May be some reasoning behind this.
