Nything similar to rsync to syncing block devices

synchronization

I cloned several 32Gb pendrives with a linux system installed using dd. Later I did shrink a partition and I did some little more changes (in the "Master"). Is there any tool for transferring only the blocks changed for evoiding the slow full re-cloning with dd?

I thought in rsync, but it only seems to work with files.

Best Answer

According to the description: Bscp copies a single file or block device over an SSH connection, transferring only the parts that have changed.

Rsync Synchronization – Syncing Directories in Both Directions

You want bi-directional sync. Take a look at unison, which does this: http://www.cis.upenn.edu/~bcpierce/unison/

For example, on Debian/Ubuntu:

$ sudo apt-get install unison
$ unison MAC/ LINUX/

If you have trouble with permissions (example ext4 -> FAT):

$ unison -perms 0 vlc-2.2.0/ /media/sf_vlc/vlc
