NAME AND VERSION

IO::BlockSync - Syncronize changed blocks

VERSION

Version 0.001

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.

Perl module:

use IO::BlockSync;
BlockSync( src => 'sfile', dst => 'dfile', chk => 'cfile' );

Executable:

blocksync -s /source/file -d /destination/file
