Oracle Enterpise linux with multipath and SAN storage

Hello Everyone,,

I have Oracle Enterprise linux version 6.32  installed on a server which is connected by fiber to SAN Storage.

This server is connected to San storage by multipath, and so I have in /dev/mapper files ( 7 byte each) that represent storage on SAN.

The problem is that, I need to backup files from the SAN storage, How I can do that??

Note: I use symantec Backup Exec 2014.

I hope your help, Thanks.
