NAME
IO::BlockSync::App - Perl module
VERSION
Version 0.002
SYNOPSIS
BlockSync can some of the same stuff that bigsync (by Egor Egorov) can - it's just written in perl.
BlockSync copies data from source file to destination file (can be a block device) and calculates checksum on each block it copies. On all runs after the first only the changed blocks will be copied.
blocksync -S -s /source/path -d /destination/pathINSTALLATION
Look in README.pod
