rsync cannot "backup" something it doesn't know about or isn't
changing... likewise your command shouldn't have deleted "extratest"

dan@framework:~/rsync$ mkdir 1temp 2temp elsewhere
dan@framework:~/rsync$ touch 1temp/test
dan@framework:~/rsync$ touch 2temp/extratest
dan@framework:~/rsync$ rsync -av --backup-dir=elsewhere 1temp/ 2temp/
sending incremental file list
./
test

sent 116 bytes  received 38 bytes  308.00 bytes/sec
total size is 0  speedup is 0.00

dan@framework:~/rsync$ ls -la 1temp

Now, if we add in '--delete' ... 


dan@framework:~/rsync$ rsync -av --delete --backup-dir=elsewhere 1temp/
2temp/  sending incremental file list
deleting extratest

sent 70 bytes  received 25 bytes  190.00 bytes/sec
total size is 0  speedup is 0.00
dan@framework:~/rsync$ ls -la 1temp

drwxr-xr-x 5 dan dan 4096 Oct 21 11:31 ..

dan@framework:~/rsync$ ls -la elsewhere

drwxr-xr-x 2 dan dan 4096 Oct 21 11:31 .
drwxr-xr-x 5 dan dan 4096 Oct 21 11:31 ..
dan@framework:~/rsync$ ls -la 2temp/elsewhere/
total 8
drwxr-xr-x 2 dan dan 4096 Oct 21 11:33 .
drwxr-xr-x 3 dan dan 4096 Oct 21 11:31 ..
-rw-r--r-- 1 dan dan    0 Oct 21 11:31 extratest

NOTE -- the deleted file went into "2temp/elsewhere", because of the
behavior of --backup-dir:

    Note that if you specify a relative path, the  backup  directory
    will  be  relative to the destination directory,
