Update to 1.43, with a number of improvements (e.g. ARMv8 optimized zero-block detection) and most importantly the dd_rescue-lzo subpackage that provides a dd_rescue plugin with lzo de/compression support.

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 an MD5 and an lzo plugin exist.

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.
