Forgot to include my commented flexbackup.conf - I have filled in comments from other config examples - I am not saying they are all right or that I understand all of them

--- Sample flexbackup.conf ---
# Parameters for 'afio' only - set true to show block numbers
$afio_echo_block = 'false';
# Files less than this size (kilobytes) won't be compressed
$afio_compress_threshold = '3';
# Maximum amount of memory (megabytes) to use for temporary storage of
# compression results. If a compressed file is bigger than this, compression
# will have to run twice on the file (see manpage).
$afio_compress_cache_size = '2';
# Block size (k) to use (default for most things is 10)
$blksize = '10';
# True to use "variable" block size for the tape device (mt setblk 0)
# If false, will use the $blksize parameter above. All non-mt commands
# will still use $blksize regardless of this value
$mt_var_blksize = 'true';
# Buffering helps streaming the data from disc to tape
$buffer = 'true'; # true to use "buffer" program
$buffer_megs = '3'; # buffer memory size (in megabytes)
$pad_blocks = 'true'; # true to pad blocks to blocksize
# The type of compressor to use (make sure its installed)

$dump_length = '0';
$dump_use_dumpdates = 'false';
# Set this to "true" to make erase operations just rewind the tape - NOT call "mt erase"
# For some tape drives, erase takes hours rather than seconds The key thing is that mt
# cannot erase our tapes correctly , so you need this :-
$erase_rewind_only = 'true';
# If true (default), level zero "all" assumes you want to erase and use
# a new tape. If false, level zero "all" appends like all other backups
