It's not a theme, just some basic color palette with green for preprocessor, yellow for keywords, cyan for string and numbers and white for the rest. Dark gray for the comments. Re: animations - yeah, they are all custom, but there's not really much to them. The hardest part was to do flickerless fade-ins and -outs, the code for that just ain't pretty. Window transformations are just DeferWindowPos with the right com…

Yeah I can imagine. Win32 was never designed for animations like that :) You appear to have done a pretty remarkable job though as they are some of the best I have seen in Windows outside of things such as WPF. Well done! Do you blog at all? I imagine you have some very interesting things you could talk about in regards to Win32 programming. Understandably there are fewer and fewer pure Win32 developers these days an…

* Whoops, thanks, my brother's tablet :-/

No, sorry, don't blog and can't mentor you. I just don't have time for either.

Author's here. A bit of a background on the project if I may. I wrote the original version several years ago. It was purely for myself, to automate the way I was doing the backups at the time. I also threw together a website and put it online, just because and with no hope that something this simple would be in demand. Then went on doing other things like having kids and what not. Fast forward to 2012 and there's a c…

What would the advantages over a tool like FreeFileSync be if I don't care about real-time backups? (Note that I understand that it's designed to be very simple and usable, and there's real value in that, but I'm specifically asking about the features.)

No problem, I totally understand. Best of luck with Bvackup.

PS I realised you are the guy behind Hamachi. I used that a lot a while back so thanks for that also!

I'm most interested in the delta copying. After a little bit of research in the forums I'm guessing you save block hashes of full copies and then compare the source blocks to the block hashes and copy only if they differ. Or does the app install a driver to get the changed blocks in files without rereading the whole file?

It's former. It splits files into blocks (defaulting to 32KB, but that's configurable), computes hashes (two separate hashes per block) and stores them in a file in the backup config directory. These are used to detect modified blocks. It also computes a hash of an entire file and stores it in the same hash file. This is used to hedge against false negatives with modified block detection. The original version (from '…

Do you use the rsync algorithm, so that bytes additions/deletions are efficiently handled ?

I have been thinking about my own backups for some time. Do you guys prefer rolling your own setup for full system backup or use services like CrashPlan? Do you guys trust services like S3/Glacier? When backing up your system do you bar specific files from being backed up like GPG/SSH keys, etc.?

I'm in the same situation. I use CrashPlan but I've heard CrashPlan has failed in the past so I just wanted another layer of security. I was thinking of finding some app like Tarsnap (and it should work with Glacier) that handles de-duplication really well. I had read that Cyberduck can be used to backup to S3 and in-turn we can make a "rule" in S3 that after "N hrs" data in S3 should be sent to Glacier. But I don't…

These are all good tools but I am worried about using Amazon's infrastructure. They would gladly hand over your data.

Actually you can encrypt that data on your end.
