# Run a simple backup of the Bacula build directory
#   then restore one file and see if we read too much
#   data
#
# With AWK, we get the 1st executable file from the volume we get the also a
# "position" of the file in the volume with NR (line number).
#
# With grep "FI=nn SessId=", we search in the trace file up to which FI we read the data.
#
# For example, if we find build/libtool NR=6, the trace file should have all
# FileIndex<6 (probably between 3 and 5) If we find a FI=6 in the trace file,
# it means that we read too much data
