DIY: Free Windows backup tool Synchronicity

Synchronicity is a free and reliable backup solution. See how to create a new, scheduled backup to an external drive using the tool.

It isn't always easy to get people to back up their systems. Sometimes end users are being lazy, but sometimes the problem might be that the backup tool is difficult to use. A free, volunteer-developed tool called Synchronicity can have end users backing up (with scheduled backups) with ease without having to spend all day configuring those backups.

Synchronicity's features

  • Easy to use interface
  • Backup easily to USB
  • Inclusion/Exclusion
  • Scheduled backups (with automatic rescheduling of missed backups)
  • Mirror
  • One-way incremental
  • Two-way incremental
  • Multi-profile support
  • Plenty of documentation (including hidden features)
  • Portable
  • Advanced features (such as dynamic destinations, time offsets, loose timing, file size comparison, and more)
In this quick tutorial, I show how easy it is to create a new, scheduled backup to an external drive using the Synchronicity tool. Note: The requirements for Synchronicity are .NET 2.0 or greater and the admin password (if applicable) to the machine.


Download the package with the installer included, double click it, and walk through the installation. Once it's installed, there will be a new menu entry in the Start menu called Create Software. In that menu, you will find the Create Synchronicity sub-menu, which includes the Create Synchronicity executable (and the uninstaller). Click Create Synchronicity to start the setup process.

Create a new backup

When you start Synchronicity, you will see the main window (Figure A). From this window, click the New Profile button, which will ask for a new profile name. Figure A

This window will list all configured profiles. Multiple profiles can be saved for various backup jobs.
Once the new profile name is added, the Profile Settings window will open (Figure B). In this new window, you must configure the following:
  • From: Target to backup.
  • To: Destination to backup to.
  • Subdirectories: Subdirectories for both From and To.
  • Synchronization Method: Which way is the backup sync'ing.
  • Include/Exclude
Figure B

Not many backup solutions are as simple as Synchronicity.

For folder locations, you can use the following path formats:

  • Absolute: D:\Path\to\folder
  • Relative: ..\..\folder
  • UNC: \\IP_ADDRESS\folder
  • Volume Name: "Drivename"\folder

Once To and From have been set, click the Local folder tree button to reveal the directory structure. In this directory tree, you can include/exclude specific subfolders. If you need to include/exclude specific files, you must uncheck Copy All Files and then select what you want to include or exclude.

In the include/exclude section, you can use the following:

  • Files by extension: As in tar; zip
  • Files by full name: As in "File.exe";"File2.exe"
  • Regular expressions: /File[0-9]+\.(doc|xls|ppt)/

After you complete those steps, the new job will be listed in the Profiles section. If you click on that job, a drop-down will appear where you can do the following:

  • Preview
  • Run (Synchronize)
  • Change settings
  • Delete
  • Rename
  • View log
  • Clear log
  • Scheduling
If this is to be a scheduled job, make sure to select Scheduling. When doing this for the first time, you will get a prompt that says Synchronicity must be run as a startup program. By enabling a profile for scheduling (Figure C), Synchronicity will register as a startup program. Figure C

If you want Synchronicity to catch missed backups, you must check the box for the feature.

Bottom line

Synchronicity is one of the fastest ways to help get end users (and clients on a tight budget) to back up their files and folders. Synchronicity will not image a machine, but for some users just getting that data backed up is a huge step forward.

The project mastermind held to the statement that the project would finish "On time and under budget" and a number of decisions made in an attempt to fulfill that promise ultimately led to further delays. Many key people resigned. (Including me) because of a,b and c. That project has to be completed because many have staked their reputation on it and they have gone too far to turn back. But it wont be pretty.


I also use TrueCrypt both on the backup drive and also on my laptops drive for any private data - I mirror that private data drive as the single encrypted file, but have to unmount it first before using SyncToy....


FreeFileSync is worth a look. Doesn't schedule but very user friendly. I started using it when my MS SynToy stopped working a couple of years ago. FFS now adjusts for timezone shifts which is of critical importance if you move your computer between timezones. I put my backup (of my whole data drive 30 gig) into a TrueCrypt volume, in case my external drive is stolen. I don't think this would be very easy to automate.

As its name implies, this tool is for syncing (/cloning/mirroring) folders. For admins, "backup" means being able to restore older versions of files, not just the latest. For left-to-right differential, it does says "In this case, the right folder somehow keeps an incremental history of changes that occurred on the left."--I'm not sure what that means exactly. There is the dynamic destination feature, however that would seem to require a full sync for every dated folder, taking up a lot of time and disk space. rsync, which is also mainly for syncing, can also be set up to create dated destination folders, but it allows making the the dated folder incremental, and can use hard links as a form of deduplication, saving a lot of both time and disk space. Unfortunately, hard links are not available in Windows. A tool called Syncrify seems to offer syncing ability, versioning, and incremental deltas. Neither of these sync tools can backup and restore Windows itself.


I've been using Microsoft SyncToy for a long time. Worked well for me for backup/sync on demand. The 2-way sync part was especially helpful for carry data around between my PC and USB memory stick. Thought if using cloud storage, but since my internet bandwidth is not unlimited and cheap, I'll use it mainly to share stuff with others. The attractions of Synchronicity for me is the ability to schedule the backup and comprehensive logs. The downside is the lack of 2-way sync/backup. I would use it for backing up my local drives on a regular basis automatically, but for portability of my data, I'll continue to use SyncToy.


My question is and will always be: How good is the backup/restore process?


In my time I've tried hundreds of them. All have their strong and weak points, each has features I've wished others had thought of, some log better than others and some are pure agony to try to use. One in particular I can think of (I'm looking at *you*, Microsoft Synctoy) are easy to configure and a nightmare to change that configuration. Bottom line: with all the options out there, what makes this offering stand out from the Cobians, SyncBacks, and GoodSyncs?


I never use this app in the past but according to the screenshot and explanation, the restore is as easy as to copy back the data to the original location because this backup software works in syncs methods just like Beyond Compare. I will test, this is good for small companies with small budgets or for home users.


I think from an admin perspective you can do with any of the backups you mentioned. I think Synchronicity tends to be a bit more user friendly. And I realize this doesn't matter to most users who need backups, but the fact that it's open source means the chance of it dying off or becoming a paid-for software are slim to none. The reason why I believe this is because this backup is a good solution and, should the developer up and quit, it could be picked up by another developer or even forked.
