Actually, I would extend the first 3 values a bit:

blocksperrecord 512
records 64
checkpointfreq 1024
readerprocesses 6
maxretries 5
retrylimit 5000000
maxvoluses 200
filesperfsm 2000

LTO-2 is a high density, very fast tape device so you want to keep ahead of the tape drive with large records and less overhead for checkpoints. If you are backing up more than 100,000 files, change filespersm to 5000 to also reduce the overhead. ALWAYS use an fbackup config file with modern tape drives.
