I got to know about this from lwn.net and Froscon. Thanks for a nice software. I want to know about minimizing space. Assume I have
condition 1: If all three above files are identical:
If I run a simple ‘backup’ - will it cost me 3 X disk space of each file (+some json + other small + overhead)
condition 2: If file_AAA.iso is identical in SHA1SUM to file_BBB.iso will it minimize the size to one ISO size?
