The RAID 1 set is the operating system, NBU, etc. and not used to house backup data.

In addition to above post, you may want to have a look at this guide:

Symantec NetBackup 52xx Appliance Hardware Installation and Initial Configuration Guide: DOC7454 

p.11:

Product overview
Two disk drives in a RAID 1 configuration provide the operating system for the appliance. These disk drives are located in slots 0 and 1 in the appliance front panel.

one nmore query :

FS /inst is used for which purpose. like /cat is used to house DB.

/dev/mapper/system-inst
                       50G  3.7G   44G   8% /inst

[symantec040]

/inst is the location where you have place the software upgrade files etc.,

whenever you wish to upload new appliance maintenance patch for upgrade purposes, you should place it inside /inst/patch/incoming/

Once there, then you need to validate whether that file is intact, either you do it by md5sum checks or go to

Main.menu> Manage>Software>List downloaded

Here, the file you uploaded will be verified, only once that verification is successful, you can proceed with

>install <file_Name>

Thanks.
