What platforms does Concentsus Home support?

The Concentsus Home module currently supports Windows Vista, 7, 8, and 8.1, preferably with NTFS.

Most Windows Vista users will be using NTFS, unless you upgraded from a previous version of Windows. If you are running Windows with a FAT32 file system, Concentsus will be unable to back up any files that are opened or locked when the backup is run. Windows Server 2003, 2008, and 2012 are only supported with Concentsus Business, the professional version, at our Business page.

I have a small business. Can I back up my server for 4.95 per month?

Concentsus Home is for home, non-commercial use only. If you are running a small or home-based business, please refer to our Business page.

Note that aside from the terms of service, there are some important differences between Concentsus Home and Concentsus Business. Refer to our comparison chart for more details.

Can I use Concentsus if I am behind an HTTPS proxy?

Concentsus Home does not have proxy support, which means that it needs direct outbound access through SSL port 443. If you need HTTPS proxy support, check out Concentsus Business at

Is Concentsus secure?

Absolutely. When you use Concentsus, your files are encrypted on your computer using 448-bit Blowfish encryption and then transferred to the Concentsus servers using 128-bit Secure Socket Layer (SSL) encryption. You have the option of using a Concentsus key or your own private key to encrypt your data. Note that if you use your own private key, you must be very careful about not losing it because if you do, we won't be able to help. It's impossible for us to decrypt your data when you use your own key. Most users opt to use the Concentsus key, but the choice is yours.

I'm worried about privacy. How does Concentsus respect my privacy?

Concentsus is committed to protecting the privacy of our customers. We do not read your data or share it with ANYONE. Read our privacy policy for further information.

Any suggestions on what I should back up?

We recommend that you back up data that is difficult to replace, like photos, email, contacts, financial records, and office documents.

How do I restore my data?

There are three ways to restore your data:

The first restore option is to simply right-click on the file that you want to restore and select "Restore."

You can then select the version to restore, from the most recent version up to 30 days back. You can also right click on the file folder you want to restore and select “Restore Files in Folder.”

The second restore option is to restore via the Concentsus Virtual Drive. You can find this when you open up "My Computer" on your machine and select the Concentsus icon from the "other" category.

The third restore option is to restore via the web. Go to the login Restore page, and select the computer and time/date you want to restore data from. Select all the data you want to restore. You can then choose whether or not you want to restore via download or, for a fee, have a DVD shipped to you. Make your selection, and the restoration process will begin.

Depending on how large the restore is, it could take a few minutes or a few hours for Concentsus to prepare the data for you. You will be notified via email when your restore is ready to download. When you get the email, go to your Account page and from there you can download the restored data.

How often can I restore my data?

You can restore data as many times as you need to. Concentsus Home users are limited to one restore in the build queue at a time, though multiple files may be requested within the restore.

What is backup, according to Concentsus?

You can think of it in the same way you think of a backup copy of a paper document—that is, if you lose the working copy of the paper document, you go find the backup copy. In other words, the primary copy of your files or data will be maintained as the working copy on your machine.

If you delete the working copy on your machine and then run a backup, Concentsus will assume that you no longer need a backup copy, and will mark the file to be removed from our system in 30 days. (We keep it on file for 30 days, in case you change your mind.) After 30 days, you cannot get these files back.

If you want Concentsus to keep the files after they are deleted from your computer, this is referred to as an archiving service and is currently not offered.

How can I view the status of my backup?

Double-click on the Concentsus tray icon and it will give you an idea of how your backup is progressing.

Are there any size limits or other constraints to the types of files I can back up?

You can back up pretty much any type or size of file. However, a few operating-system specific files can't be backed up, like the pagefile or prefetch files on Windows.

Can I share my backed-up data with another user?

No. Concentsus is not a file sharing service—it's a backup service. While you can technically give your name and password to someone to access your backups, we strongly advise you not to share your password.

How many files can I back up?

Lots. Like tens of thousands. Concentsus is getting better all the time, and we've had reports of success up to 200,000 files. But note that Concentsus will start to slow down when you try and back up hundreds of thousands of files, so don't go thinking you can back up massive source code repositories or something, because you won't be happy with the performance.

I have LOTS of data. How long will it take to back up?

For a typical system on a typical broadband line, Concentsus backs up data at about 2-4 GB per day. But if left undisturbed on a fast connection, you can back up over 9 GB in a single day.

You may experience faster or slower speeds depending on your connection. You may want to check your favorite bandwidth meter test to measure your broadband connection.

Will it take that long next time?

Concentsus does what are called differential backups, which means that it only backs up portions of your files that have changed since the last time they were backed up. This saves lots of time, bandwidth, and storage space. After your initial backup, subsequent backups are relatively quick, and chances are that you won't even notice them.

What if my internet connection disconnects while Concentsus is backing up? Or what if I shut off my computer in the middle of the backup?

That's not a problem. Concentsus will just continue where it left off next time you are online.

How do I cancel my Concentsus account?

Uninstall the application from your desktop, and then log on to your account at Under "My profile," select "delete account," and your account will be cancelled. All of your information will be completely deleted from Concentsus’ databases within 24 hours.

Will Concentsus back up my entire disk drive? What about my applications and system files?

Concentsus was made to back up your most important files (email, contacts, photos, financials, etc.), but not your system and application files, which are easy to restore via your original CDs.

Technically, you can back up your applications and system files, but we don't advise this. This is done for what's called a "bare metal restore," which is not what Concentsus was designed for. Typically, if your computer dies, you get new hardware, and attempting to just image your new computer with your old disk image via Concentsus (or any other backup application for that matter) is a tricky endeavor.

How does Concentsus keep my data from being lost?

We utilize a proprietary protection mechanism based on a type of distributed Reed-Solomon encoding (Galois fields—lots of hard math) to ensure that your data is safe, even in the event of multiple hardware failures.

Does Concentsus support network drives? What about external drives?

Concentsus Home does support network drives. Here are the steps:

  1. Double click on the Concentsus logo in the bottom right corner of your system tray.
  2. Click on Configure.
  3. Click on the File System tab and then right click on My Computer and select Add Network Share.
  4. You will then need to enter the name of the network share path along with the administrator user name and password and click OK.
    1. Share = network path of the mapped drive
    2. User Name = Administrator (if you have the password, type it in; if not see your IT person)
    3. User Name = Everyone (just leave the password field blank and click OK).
  5. The shared drive folders will now appear. Click on the folders and/or files you wish to backup and click on Save
  6.  in the bottom right corner to save this new backup set.
  7. You will now need to click Start Backup to backup this new configuration.
  8. Note: This process will need to be completed for all network shares that you wish to include in your backup set.
