Best Parctice to Backup ACFS DBHOME

Hello!
We are start to use ACFS Filesystem for Our ORACLE_HOME (DB).
Now, Like to Take Backup via 3rd Part TAPE Backup System Like Networker (EMC - AKAS Lagardo).
But Networker can see not  my mount point, because it use /etc/fstab for mounted file system list.
In ACFS configuration for DBHOME this done by CRS/GI.

So My question for forum how you guys doing this?

Thanks, Shafi
