11 years agoCompletely exclude mpoints when running rsync
Nikos Skalkotos [Fri, 18 Jan 2013 18:45:32 +0000 (20:45 +0200)]
Completely exclude mpoints when running rsync

We used to exclude mount point from rsync with options like this:

 --exclude mount/point/*

This will copy the directory and leave out all files under it. In
some cases, this causes problems because rsync will fail if it
cannot stat the directory and some mount point will only return
stat info to their owner and not root. Even if this wasn't the
case, we cannot determine the real directory attributes. The stat
syscall will return the attributes associated with the mount
options. It's better to completely exclude those mpoints in rsync
and create them explicitly after the command runs. We make them
inherit the mode and the ownership of their parent directory.
