Package: backupninja Version: 0.9.1-1 Severity: normal I'm running backupninja to do a duplicity backup. The local and remote users both use zsh as their login shell. I'm backing up /etc, /home, and a few other directories. I have an exclude=**/.svn line in my config file, since /home has such directories in it.

Note the zsh: line. ** is a special glob pattern for zsh too, but it
seems to be to be a bug that it is filtering through to zsh at all.
This is occurring due to the following in the dup script:
output=`nice -n $nicelevel \
su -c \
"duplicity $execstr --exclude '**' / $execstr_serverpart
2>&1"`
The su means that duplicity gets run by zsh -- and also means that one
level of quotes get stripped out, so glob patterns are seen by the login
shell, which means it's also subtly broken for non-zsh users, I think.
I haven't come up with a patch yet. I thought that replacing su -c with
sh -c would fix it, but that also fails, after /bin/sh manages to expand
the glob (to bin/.svn I think). Fixing the quoting of the exclude regexp
seems like the only real fix.
I think I've worked around it as follows in the config file:
exclude='**/.svn'
Although I've not verified yet if this actually excludes the .svn
directories from the backup.
