This feature will most likely require file system support or a some  
sort of restore client to rebuild the file. If you see a way around  
this then please let me know.

One of the LBackup project goals is to ensure that restore operations  
are as simple as possible. Adding a client to the mix may not fit with  
this philosophy.

I am aware that a client may make certain restore features easier. But  
having access to the data without the any client requirements is a  
feature of LBackup.


Because disk space is fairly inexpensive and this feature will only be  
of benefit in certian circumstances. An optional plugin could be a  
good way of implementing this idea. Particularly because this feature  
has the potential to reduce the reliability of the backups.

I certainly think that this is a possible way to move forward. I am  
not against implementing such a feature to see what it is like.  
However, this could be time consuming and it sounds like you would  
like to get this backup running ASAP.

I have a Windows XP machine and have installed cygwin with rsync. I am  
now in the process of looking at how to setup SSH access on the machine.

If you need a time frame right now, then there is Lucid has a partner  
company in Japan who may be able to offer you professional support  
with Windows backups using rsync.

Also, I would guess that the someone on the rsync mailing lists has  
actually done this before.
I have posted a question to this list to find out how complex/reliable  
rsync is for windows backups.

I will continue to do some testing and will be back in touch with you  
once I have more information.
