Hello Ajit,
I am using Backup Exec v10d. The SCL does not list compatibility with RHEL 4 AS (x86_64). I have already logged an enhancement request. The initial documentation I read was a bit confusing because RHEL 4 AS was listed as compatible (later figured out that only X86, not X86_64 as compatible). I have already made a substantial investment in Backup Exec and multiple agents.
Unfortunately, I am still left with a RALUS agent I cannot use, and looking for alternatives so that I can back up all of my servers from one tape library (Windows 2000 & 2003, RHEL 4 AS X86_64, & Solaris 7)
