VSS in Windows handles this natively, you just have to access the appropriate providers
Can you elaborate?
Sorry I can't be more specific
It would be nice if you'd specify on pricing page [1] what is the price for in sense of time - a month? a year? [1] https://bvckup2.com/purchase/
Erm ... it's an installable standalone program. The price is for lifetime. I thought it was obvious.
This may sound strange, but I don't understand how I'd use this for backups. It seems like all it does is sync one folder to another, potentially in realtime. That's essentially RAID1 at the filesytem level, but RAID isn't a backup! What if I accidentally overwrite the contents of a file; how would I recover the previous version?
There are backups and there are backups. For some people, like yourself, archiving backup is the one true backup, while others make do with rolling hourly/daily/weekly backups or even something as rudimentary as copy-pasting folders by hand. Ideally, yes, everyone should be doing versioned backups to a zfs storage cluster. In practice, no, lots of people have just enough motivation to get an external drive and start…

Actually, I was thinking of rolling hourly/daily/weekly backups and I didn't understand how I would set that up with your program. Would I have to sync the same source to multiple destinations on different schedules? That seems inefficient compared to e.g. http://www.mikerubel.org/computers/rsync_snapshots/ Please don't get me wrong, I'm not trying to denigrate the software you've written! I was just surprised to see…
Why is it that you are surprised to see it marketed as a backup tool? I know about bup , thanks.
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…
Shouldn't it be "backvp"?
Let's not go there. I wish I named it something else. It was a dorky name for a toy project, who'd knew it would get any traction. Incidentally, I do own backvp.com.
- says the guy who also thought of a cute but easily-misspelled name for his app. Customers sometimes mis-spell it a few different ways in the same email.
Btw, fantastic design everywhere.
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 '…
Re-calculating a full-file hash will require reading the whole file anyway. Which will take around the same amount of time as re-copying the whole file, since the sequential write speeds of most HDDs and non-entry-level SSDs are similar to their sequential read speeds. The only benefit would seem to be that your SSD might last a bit longer... but how many consumers use SSDs to store their backups?
Please let me know if I'm missing something.

Question: if I select my Google Drive or MS Cloud Drive as a backup folder, will that work? (too lazy to test) I suspect it would since both of these have hooks into the default filesystem, but I am unsure.
