rsync - Aug 2009 - snapshot support in rsync

Hi,

I have been using rsync-3.0.6 to sync my huge file system and it works
awesome. I have been getting really annoying lots of errors about "file has
vanished". We thought on getting rid of this and realized that having
snapshot support in rsync would make things much easier. Could you please
let me know if there is any way to get rid of this error message in
rsync-3.0.6? If not then is there any plan of getting rid of it in future?

Thanks a ton,
Jignesh

Rsync cannot do this [as far as I know], but there are other tools.  For 
example, if you use LVM for managing your volumes (and you should if 
you've no other volume management in use), then you can use lvcreate -s 
to create a snapshot of the volume.  This does as you desire: it provides 
an instantaneous frozen copy of the volume's content.

Be sure to remove the snapshot when it is no longer needed.  They do 
consume increasing space in the underlying storage over time.

If you use something other than LVM, then there is likely an equivalent 
to lvcreate -s.
