%description
dd_rescue helps when nothing else can: your disk has crashed and you
try to copy it over to another one. While standard Unix tools like cp,
cat, and dd will "abort" on every I/O error, dd_rescue does not.

dd_rescue has many other goodies; optimization by using large blocks
as long as no errors are in sight and falling back to small ones; reverse
direction copy; splice in-kernel zerocopy; O_DIRECT support; preallocation
with fallocate().

dd_rescue also provides data protection features by overwriting files
or disks with fast random numbers, optionally multiple times.

dd_rescue supports plugins; currently a hash and an lzo plugin exist, 
supporting on the fly hash/HMAC calculation/validation and lzo 
de/compression. The lzo plugin is packaged in the dd_rescue-lzo subpackage.

%package lzo
Summary:        LZO plugin for dd_rescue
Group:          System/Base
Requires:       dd_rescue = %{version}

%description lzo
This plugin allows you do de/compress files during recovery copying
with dd_rescue using the lzo family of algorithms. lzo algorithms
are very fast to decompress and most algorithms are very fast to
compress as well -- at the expense of somewhat worse compression than
zlib's deflate.

The plugin does offer a variety of options to handle corrupted .lzo
files with some grace; it does skip over bad blocks (if the block
headers are still intact) by default, but does offer an option (nodiscard)
to allow to attempt decompression on faulty input, hoping to produce 
some usable bytes. It can also search for valid block headers after
synchronization has been lost due to a corrupt one.

The plugin also handles sparse files (files with holes) and supports
appending to .lzo files, so it fits neatly into dd_rescue.

Some fuzz testing has been applied to the plugin's decompression routines,
though more will have to be done to feel confident about feeding untrusted
data to the decompressor; the plugin is still young and might expose bugs.
