taking into account both data integrity and decoder availability:
* The lzip format provides very safe integrity checking and some data
recovery means. The program lziprecover can repair bit flip errors
(one of the most common forms of data corruption) in lzip files, and
provides data recovery capabilities, including error-checked merging
of damaged copies of a file.
