![]() Took a while to figure this one out, I can tell you thatĪssorted 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.Īll beta versions are free, with some tasty perks in store for the beta users. 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. 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.Īlso, and it's for true Windows connoisseurs only - it can run in elevated and filtered modes using the same executable. 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. It doesn't copy just the file contents and the attributes, but also the timestamps, NTFS security and ownership information. ![]() just like Bjarne envisioned before he got sucked into that bloody language design committee. 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. The installation package is about 480 KB. 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. In fact Bvckup is as much about the UI design as it is about technical features. 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. Properly designed user interface is all about simplicity and unobtrusiveness of the day-to-day interaction flow. Verbosity is not a feature, multitude of options is not a convenience. ![]() It is not about utilizing all 16 million colors in a single toolbar icon. This adds up to some major time savings, on top of those delivered by delta copying. 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 allows it to not scan the destination directory to detect what changed, but rather rely on a locally saved summary from the last backup. By default it assumes that the destination copy does not change between the backups. 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.īvckup is not a two-way sync utility, it's a backup utility and it makes full use of the core difference. Which is a fancy way of saying that it copies only changed parts of the file. ![]() Its default copying mode is delta copying. This makes Bvckup a real-time backup utility. Once the changes are detected, it propagates them to the destination. ![]() For a quick introduction, I am firstly going to quote the authors post on the Announce Your Software/Product section, and then give you my first look introduction to the software.īvckup's default mode of operation is to constantly monitor for changes. ![]()
