If incremental backups are completing but the full backups(which have considerable large amount of data) are failing most likely its a client timeout issue, does it always fail at 315 GB? You may increase the CLIENT_READ_TIMEOUT paramter to higher value(around 3600).

Tried with 1500 before but still same error messages as i send earlier.

Looks like some files on the disk are unreadable/corrupted. If you have any idea on which folder may contain such file please do the below (change paths for Windows accordingly). It would let us know which file is exactly causing issues.

Set up logging and run a bpbkar interactive test on the directory where the files are purported to exist:

1. Add VERBOSE = 5 to the /usr/openv/netbackup/bp.conf configuration file on the client.(use Backup,Archive, recovery window to setup verbose, under troubleshooting tab in windows VM)
2. touch /usr/openv/netbackup/bpbkar_path_tr
3. mkdir /usr/openv/netbackup/logs/bpbkar directory if it doesn't already exist.
4. Run /usr/openv/netbackup/bin/bpbkar -nocont <directory> > /dev/null against the directory containing the file.

5. Disable verbosity.

Please make sure you conticue to monitor disk usage if enabling the above logs.As bpbkar level 5 logging for 315 GB data backup may become quite huge.
