Rsync and exclusions

 

an old post found back on disqr about rsync (original date : circa 2016)

You might want to use the rsync exclude options directly in your script either by specifying a file with all the exclusions to perform, or by specifying them in the command line directly :

--exclude-from <file-name with 1 pattern by line>
--exclude <file or="" dir="">

For example :

rsync -r -a -v -e "ssh -l Username" \

        --exclude 'dbconfig.xml' --exclude 'WEB-INF/classes/' --delete \

        /local/Directory remote.server:/remoteDirectory

One important thing to keep in mind when excluding a directory is that rsync will always consider the path to be relative to the source directory.

This can be used for example when you want to push your production from a Production JIRA instance to a Staging JIRA instance, but your dbconfig.xml is different (different DB auth parameters for example), and hence want to avoid some files. 

SVN backup repository with history

Copier toutes l'historique d'un repository SVN auquel vous avez accès (en lecture), 

mais pas les droits d'administration :

  svnadmin create localrepos
  emacs localrepos/hooks/pre-revprop-change # make it 'exit 0' 
  chmod +x localrepos/hooks/pre-revprop-change
  svnsync init --username USERNAME file:///path/to/localrepos https://myproject.googlecode.com/svn
  Copied properties for revision 0.
  svnsync sync --username USERNAME file:///path/to/localrepos

Source : http://code.google.com/p/support/wiki/SubversionFAQ#How_do_I_download_my_Subversion_history? 

Donc :

$ svnadmin creat localrepos

$ cat > localrepos/hooks/pre-revprop-change

#! /bin/bash

exit 0

$ chmod a+x localrepos/hooks/pre-revprop-change

$ svnsync init --username USERNAME file:///NEWREPO https://OLDREPO

   Copied properties for revision 0.

$ svnsync sync --username USERNAME file:///NEWREPO 

[...copie de toutes les révisions...] 

Sur la machine où j'ai copié l'historique, j'ai du utiliser une feinte :

$ svnadmin setuuid UUID-OLDREPO

Puis, pour changer les "checkouts" de source, svn switch :

$ svn switch --relocate https://OLDREPO svn+ssh://NEWREPO 

Et voilà !


PS : si vous avez les accès svnadmin sur les deux machines, il y a plus simple comme solution.
