Simple fast backup

Select a pair of folders and Bvckup 2 will make sure that one stays an exact copy of the other. It is light, uncomplicated and really well designed. It is also incredibly fast.

What's different


Complete backups faster
The app is very fast at bulk copying and it is even faster at updating.

Extensively optimized across the board Bvckup 2 goes out of its way to process every backup as quickly as possible.


It does just one simple thing...
The app does not compress, encrypt or FTP files. It's not a two-way sync nor is it a full system backup software.

It does just one thing - it mirrors A to B.


...and it does it really well
It's better to excel at one thing than to be average in many.

From the nuanced user interface to the high-performance core, the app is built to always favor quality over quantity.

Features at a glance

Real-time backups

Continuously monitor for changes and
back them up as soon as they happen.

Scheduled and manual

Run backups at fixed time intervals or only
when started manually.


Asynchronous I/O

Eliminate idling during data transfers by
having multiple read and write requests
running in parallel.

Delta copying

Reduce the amount of data being moved
around by copying modified parts of files
only. This speeds things up, in many cases

More on this below

Multi-core processing

Speed things up by running computationally
intensive tasks such as data hashing on all
CPU cores, but scale back when computer is
under load.

Move/rename detection

Detect files and folders being moved at
source and replicate this as a single quick
operation on the backup side.

Destination snapshots

Avoid re-scanning backup location on
every run by scanning it once and saving
its file index locally.


Device tracking

Pin a backup to a specific removable device
so that it will be run only when this device is

Backup of locked files

Use Windows shadow copying to backup
files that are locked for exclusive use by
running programs such as web browsers
or email clients.

System service mode

Switch program to run as a system service
to allow backups to continue running even
when there's no one logged in.

Archiving of deleted items

Move backup copies of deleted items into
a special archive directory and delete them
from there after a grace period.

Email reporting & alerts

Set backups to dispatch an email alert with the summary and the logs upon each run's completion.


Very large backups

Bvckup 2 has been tested with multi-million item backups and, while they naturally require a bit more memory for processing, they can still be handled with ease.

Concurrent or serialized

The app can run backups one by one, forming a queue, or it can run them as soon as they are due, all at once. And, of course, a backup may also be started manually at any time.

Backup planner

When running a backup, Bvckup 2 always
compiles a formal backup plan that can be
inspected without being executed if a "dry
run" is required.

Native 64-bit support

Installation package includes both 32- and
64-bit versions of the program, selecting an
appropriate one to install automatically.

Minimal dependencies

The app works with low-level Windows API
and has no dependencies on WMI, COM or
system services outside of shadow copying.
It also stores all its configuration on disk, in
a single directory.

Software update reminders

In addition to being able to check for updates automatically, Bvckup 2 has an option to remind you to check for updates
by hand.

As well as ...

  • External pre- and post-backup commands
  • Symlink and junction support
  • Ownership, group and DACL backup
  • Post-boot delays
  • Support for Samba NTFS volumes

Software updates
When looking for an update, Bvckup doesn't just check if a new version is available.

It also looks at what has changed compared to your version and how critical the update is for your case.
Software updates
Changes are always displayed relative to your version and grouped based on their type.
Software updates
In addition to automatic checks, the app can also be set to remind you to check for updates, manually.

This grants you full control over app's Internet activity while ensuring that you still keep an eye on the updates.

Delta copying

A couple of words on a feature that is as simple in idea as it is huge in impact.

When updating an existing backup copy of a file, Bvckup 2 detects and skips over unmodified parts, copying just the actual changes.
Disk writes are expensive and being selective with copying quickly pays off when working with large files that slowly change between the backups.

* If you are familiar with rsync, it's a similar idea. The difference is that Bvckup 2 doesn't require a second instance of itself to be running on the receiving end, meaning that its delta copying can be used with any storage facility that provides basic write access.
Here it is in action copying a 10 GB virtual disk of a just rebooted Windows virtual machine -
Modified blocks Progress so far
Copied 19 MB out of 10 GB or just 0.2% and completed in less than 4 minutes vs 19 minutes needed for the full copy.
Here is another example of updating a 256 GB TrueCrypt volume with work files and about a day's worth of changes -
Copied 1.8 GB out of 256 GB or just 0.7% and completed in about 53 minutes vs the 4 hours that the full copy would've required.
Give it a try and see for yourself the difference delta copying makes.

On stability and robustness

Needless to say that the reliability of software that is looking after your data is of an utmost importance.

Rigorously engineered

Bvckup 2 is written in a way and to the standards typically employed in development of system software.

It puts strong emphasis on using simple clean code, keeping resource usage in check and running as close to the hardware as possible.

Compared to conventional desktop software development, this is a substantially more involved approach, but it only makes sense for an essential always-on system utility.

Production ready

Prior to its first production release in May of 2014, Bvckup 2 went through a full year of field testing with over 10,000 users, covering wide range of backup configurations and storage devices.

The app has been in routine production use with thousands of our clients from over 80 countries all around the world, handling everything from small jobs to massive backups with terabytes of data. It is stable, robust and dependable.

What people say

The pedal-to-the-metal mindset of a command-line tool with a beautifully functional graphical user interface. Erez Zukerman,
Bvckup 2 is one of the best backup programs I have used in close to 20 years of doing IT work. Jeremy Martin, via in-app feedback
Best Windows backup solution I've ever used. Simple and fast, does what it claims to do with no fuss. Has to be one of the best thought out UIs I've seen in a long time. Stu Henderson, via in-app feedback
One of the best backup utilities I've seen for a long time. Rob Schifreen,
Holy sh#t... just tried bvckup2 on the same directory. Went from 13 mins 29 secs to 1 min 9 secs to move the same data! Courtesy of /r/sysadmin
