Bvckup - high speed "delta" sync

Submit portable freeware that you find here. It helps if you include information like description, extraction instruction, Unicode support, whether it writes to the registry, and so on.

Not exactly related but from the same developer comes CCSIO, Cold-Cache Sequential IO
... little Xmas side project ... It's a little benchmark that tries to find the best way read/write large files at a given location, be it a local volume, a virtual mount or a remote share. The way it works is that it goes through a list of (io-buffer-size, io-buffer-count, io-mode) combinations, measures bulk throughput for each and tallies up the results.
Homepage - https://ccsiobench.com - has exact benchmark description and there's a longer, more technical description over at Fundamentals of Fast Bulk IO page

I'll check this out solely based on the author. I was very impressed both by the interface as well as program capabilities.

Same author does it again :-)
As you've probably guessed from the post title it's a real-time disk IO monitor. Not hard to do by any means, but what makes it interesting is how it visualizes the data. In short - when it draws a vertical bar to display a byte count, it factors the value into megabytes, kilobytes and bytes and then displays each of these separately, in their own dedicated "band". In long - see here for an explanation how to read this graph and why it's done that way to begin with.

If you feel like playing with it, there's a dev build - https://bvckup2.com/files/io-monitor.exe
...
70 KB, no dependencies, just save somewhere and run.

The CCSIO program do you mean? I ran it and while it saved no settings to a file anywhere it did save one setting (AskForResults) to the following locations in the registry:

Code: Select all

HKEY_CURRENT_USER\Software\CcsioBench
HKEY_USERS\<userID>\Software\CcsioBench
This setting appears to be based on the user selection after exiting the program (and only for the first time?), when the program asks the user if they'd like to submit a report of the benchmark to the dev to help some research.

real-time disk IO monitor
Yeah that's awesome. I never stop getting caught off guard by really great data visualization.

The program doesn't seem to save any settings (apart from maybe drive) so it's probably portable. It also takes up 1.6 megs of RAM so that's really nice. This could be a great indicator of system bottlenecks without itself becoming part of the problem.

Wishlist:

* Ceiling CPU usage, meaning if it goes above (for example) 5%, it pauses itself. I say this because, during a copy from a SharePoint site, I got up to 15%, which is a little high.
* Maintain the current RAM usage
* Ability to monitor network connections using a similar format
* Quicky readme/intro/help view that explains the UI a little

Other nice things:

* Run from the notification area (not task bar) and ability to hover over the icon to make the window appear, go away once you stop hovering
* Ability to observe multiple sources at once
* Customize visual refresh speed (right now it's at roughly 0.5 seconds)
* Ability to resize window and have it scale accordingly
* Optional trend line

In terms of portability - nothing is saved anywhere. It always starts at the same spot on the desktop and defaults to C:\. In fact, if there's no C:\ it will complain and exit.

> Wishlist

Got no time for any of these, sorry.This was meant more as a demo for how to visualize spiky data rather than an actual supported tool.

> Other nice things

You can do that by launching multiple copies of the program.

> * Customize visual refresh speed

The latest version supports this, see https://twitter.com/bvckup/status/992355150663704576 for a screenscap

PS. A new release of Bvckup 2 is out, includes some changes that I think are quite interesting... though it's probably of not much relevance here since it's not a freeware.

@vacherin
If the developer has provided an easy and simple way to run Bvckup in portable mode I might have purchased it.

@smaragdus - I am the developer. The program is portable in a sense that the whole config is kept in a single folder, which can be easily specified. However the license is bound to a machine. It can be rebound to another machine and the binding tolerates OS reinstalls and incremental changes to the machine itself, but it is not designed to be routinely moved between the computers. I suspect you already know that, so this is just to clarify the state of affairs for everyone else.

@vacherin
I never ask questions if I know the answers. Thanks for clarifying that Bvckup is licensed per machine, not per user. Is an external drive regarded as machine? I have portable commercial programs which save the license within the data folder so one can have such programs on external drives. I have an old version of Bvckup (1.0.1.401) which writes to Windows registry only uninstall information. Does version 2 retain the same behaviour? I have two machines but I use only one of them yet I don't like when licenses are bound to machine because this restricts my freedom. Anyway, thanks for the information about the new version.

No, the license is bound to the computer, not a drive. In fact, it is *not* bound to any drives.

> Does version 2 retain the same behaviour?

Yes, it does. There's a free version of Bvckup 2 - the last release from the beta cycle (which is the one this site's entry is about).

Few freeware programs here on the site are actively supported in anything but a casual way. Just throwing that out some suggestions for a cool program idea.

I typically do the same if someone shows me anything :-)
I'm just saying how things are on my end so not to give any false hopes.
