>Description:
Somehow, xz can't archive files with two dots (just a guess, take a look at how-to-repeat).

If I rename file - archiving went just fine.
>How-To-Repeat:
$ mkdir tmp1
$ cd tmp1
$ echo "bla bla" > a.1.log
$ xz -z a.1.log > a.1.log.xz
xz: a.1.log.xz: File exists

$ ls -l
total 4
-rw-r--r--  1 user  wheel  8 13 apr 14:45 a.1.log
-rw-r--r--  1 user  wheel  0 13 apr 14:45 a.1.log.xz

>Fix:
Don't use such names? ;)
