Bscp – Secure and efficient copying of block devices
Bscp copies a single file or block device over an SSH
connection, transferring only the parts that have changed.
In other words, it handles the edge case where RSync fails.

bscp SRC HOST:DEST [BLOCKSIZE] [HASH]
65536 (64 KiB).
HASH algorithm is
Bscp is similar to the classic
but provides the following advantages:
It doesn't have to be installed on server side.
It uses a stronger hash algorithm (SHA-1 instead of MD5),
which is also configurable at command line.
DEST is allowed to be larger than SRC.
In that case,
SRC is copied to the beginning of DEST
and the end of DEST remains untouched.
The client-server protocol is designed to
communicate in bigger chunks,
so it is more suitable to
network connections with bad latency.
