Although + this option makes gzip safer in the presence of system crashes, it + can make gzip considerably slower. + + gzip now accepts the --rsyncable option. This option is accepted in + all modes, but has effect only when compressing: it makes the resulting + output more amenable to efficient use of rsync. For example, when a + large input file gets a small change, a gzip --rsyncable image of + that file will remain largely unchanged, too.
