[michael mendoza]

Hi, i don't write so much englisk, look at this>


~in the same line
#rsync -avz --stats -e ssh desc ~ 
~root at 200.109.51.119:/home/mike/Desktop/
Password:
building file list ... done
desc/
desc/prueba/
desc/prueba/a
desc/prueba/b
desc/prueba/p/
desc/prueba/p/c
desc/prueba1.tar

Number of files: 7
Number of files transferred: 4
Total file size: 10240 bytes
Total transferred file size: 10240 bytes
Literal data: 10240 bytes
Matched data: 0 bytes
File list size: 149
Total bytes sent: 479
Total bytes received: 100

sent 479 bytes  received 100 bytes  128.67 bytes/sec
total size is 10240  speedup is 17.69
[root at tyto4 mike]# cd desc/
[root at tyto4 desc]# du -sh
52K     .

now, in the host destination look at:

machine:/home/mike/Desktop# cd desc/
machine:/home/mike/Desktop/desc# du -sh
24K     .


I don't understeint that, why? in the source is 52 k
and in the destination is 24k
