cannot backup >8gb file using tar
fbackup and frecover is the solution when old tar program cannot backup file over 8GB.
here is the convention
backup to tape device
tar -cvf /dev/rmt/0m /path/to/backup1 /path/to/backup2
fbackup -vf /dev/rmt/0m -i /path/to/backup1 /path/to/backup2
restore from tape device
tar -xvf /dev/rmt/0m
frecover -xvf /dev/rmt/0m -i /path/in/fbackup -i /path/in/fbackup
the -i specify the path your backed up in your tape, it’ll extract it in your current directory.
