Also i have noticed that LVM for /opt has been backed up but not in /cloudfs/odabr (given destination).

It seems you don't have the required free space in your VG named VolGroupSys.
Check this note -> ODA (Oracle Database Appliance): ODABR a System Backup/Restore Utility (Doc ID 2466177.1)

There it is written as follows;

About LVM snapshot size by default odabr  is creating LVM snapshots with the following size:

root LVM snapshot  30Gb
opt  LVM snapshot  60Gb
u01  LVM snapshot 100Gb

Following the original from factory LVM volume size.
If for any reason, your LVM volume are different in size and or you have less then 190Gb of available free space, you could override these using -rsize/-osize/-usize command option.

Note that, you must guarantee enough free space to keep all blocks changes..
