I would guess the client rsync was upgraded to 2.6.3pre1.  See the
email below.

Unfortunately this version changed its argument parsing, rendering
it incompatible with the way BackupPC passes the exclude options.

Rsync has been fixed in CVS, but I don't know when the next release
will be.

Assuming my hypothesis is correct, the best option is to downgrade the
client to rsync 2.6.2.

This issue should now be resolved.  File::RsyncP passes the exclude
arguments to the server/sender via ARGV, rather than via the socket
interface.  ARGV support for server/sender exclude arguments was
removed in rsync CVS, since it wasn't a supported feature.  But the
rsync developers recently re-added support at our request.  2.6.3pre1
does not include the fix, but the next release should have excludes
that work correctly.  See:

    https://bugzilla.samba.org/show_bug.cgi?id=1660

I'm also updating File::RsyncP to implement excludes in the correct
way, via the socket interface, rather than exploiting a non-supported
feature in rsync.
