Synchronizácia pomocu unison alebo rsync

pripravime si scenerio na testovanie:

# mkdir testdir1
# touch testdir1/foo testdir1/bar
# mkdir testdir1/null
# touch testdir1/null/foobar
# mkdir testdir2

spustíme unison:

# unison -ui text testdir1 testdir2
[…]
testdir1 testdir2
file —-> bar [f]
file —-> foo [f]
dir —-> null [f]

pekne nám to oznámi co presne spravilo, skoplo 2 fajly a 1 zložku

Rsync – klasika

rsync -av -e ssh /DIR-1/* USER@pc-2:/DIR-2/

samozrejme musí byť rsync na oboch PC

-v je verbose čiže nám vypíše potrobné “dianie”
-a (archiv mod, eqvivalent k -rlptgoD) +-je rekurzia bez hardlinkov
-z kompresia
–exclude ktore fajly NECHCEME skopirova5

rsync -avz --exclude file1.txt --exclude dir3/file4.txt odkial/ kam/

reálny príklad može vyzerať neako takto:

rsync --recursive --perms --verbose --progress --stats --times --links --compress --exclude=".svn" --exclude="*~" --exclude="*.bak" --exclude="zend_cache--*" /var/www/google/api.bk/ /var/www/google/api 2>&1
