Deleting PAGE and ROLL files

Hello,

We are migrating to ECC6 Ehp4 / WAS701.

In our current systems, during offline backups, we delete the PAGE and ROLL files:

`/bin/rm /usr/sap/<SID>/DVEBMGS<nr>/data/PAGFIL<nr>`;

`/bin/rm /bin/rm /usr/sap/<SID>/DVEBMGS<nr>/data/ROLLFL<nr>`;

1. Is still worth doing this in WAS700 EhP1?

2. What is the benefit of doing so?

Thanks in advance for your answers.
