Copying with rules and VSS

[Contro]

I would like a soft for :

a) Two folders containing subfolders and files
b) Each folder in a local area networks (two PC)
c) When a subfolder don't exists in the target or the source is created (copied)
d) When a file don't exists in the target or the source is copied
e) using VSS (Volume Shadow Copy Service) for locked files

Better is freeware. Best Regards

Not sure if its still under development, but it certainly sounds like something you could use

First
Bvckup's default mode of operation is to constantly monitor for changes. Once the changes are detected, it propagates them to the destination. This makes Bvckup a real-time backup utility.

Second
Its default copying mode is delta copying. Which is a fancy way of saying that it copies only changed parts of the file. This makes Bvckup fast, really fast. Lots more details on why and how along, mind you, with the list of drawbacks of this particular approach is available here - Delta copying, explained.

Third
Bvckup is not a two-way sync utility, it's a backup utility and it makes full use of the core difference. By default it assumes that the destination copy does not change between the backups. This allows it to not scan the destination directory to detect what changed, but rather rely on a locally saved summary from the last backup.

I hear you say "bah, so what?". Two words - NAS backups. Not needing to scan the destination directory eliminates a lot of network traffic, and it removes the need for spinning up otherwise idle disks on NAS devices. This adds up to some major time savings, on top of those delivered by delta copying.

Still with me? A bit more perhaps?

Fourth
The user interface. It is not about utilizing all 16 million colors in a single toolbar icon. Verbosity is not a feature, multitude of options is not a convenience. Properly designed user interface is all about simplicity and unobtrusiveness of the day-to-day interaction flow. A small example would probably go a long way here - Bvckup toolbar - but the only sure way to appreciate the UI polish is to take the app for a spin.

In fact Bvckup is as much about the UI design as it is about technical features. This bit explains how tightly these two are intertwined in case of Bvckup and how they shaped the design of the app - Short history of Bvckup.

Fifth
It is small and very lean. The installation package is about 480 KB. That's as much as a splash screen logo of some other backup products  The app is written in C++ but without any extensive use of ++ features. It's much more like C with Classes... just like Bjarne envisioned before he got sucked into that bloody language design committee... but I digress.

Sixth
It is technically sophisticated. It doesn't copy just the file contents and the attributes, but also the timestamps, NTFS security and ownership information. If it finds a file that it cannot copy (locked, open, etc), it will try and use Volume Shadow Copying to work around the problem. If it is running under stripped-down administrator account on Vista or W7, it will prompt and offer to elevate itself to full admin privileges.

Also, and it's for true Windows connoisseurs only - it can run in elevated and filtered modes using the same executable. In fact, the even more amazing feat is that the very same executable can interact with Shadow Copying service on both XP and Vista; even though Microsoft explicitly requires linking to two different VSS libraries for these two platforms. Took a while to figure this one out, I can tell you that

A bit more...
Assorted bits and pieces of some interest - built-in software updates, linear regression ETA estimator, the built-in interactive Mini Guide shown on the first run, a bit of a logo and web design goodness and a bit about myself.

And lastly...
All beta versions are free, with some tasty perks in store for the beta users.

I'll take a good look.

Ejem. I am posting in the bvckup forum to determine the way I can do the above things.

I should have mentioned, I am not affiliated with Bvckup in any sence.  I simply wrote a review on it a while ago and figured it may be of some use to you

I am trying Stephen .
A nice program indeed.
But perhaps don't do what i need.
