I have no LZO support (no LZO library) on my director and storage daemon.
Client backup with LZO and restore works fine. When restoring LZO compresses
files to a client without LZO compression a warning appears:
Warning: Compressed data stream not supported on this Client.
When restoring the same data on a client with LZO enabled all works fine.
So, at least on my FreeBSD systems, LZO is not needed on SD and DIR only on
client.
