Comodo Backup Review

Comodo Group is well known for producing reliable security software.  Comodo Backup is their entry into the data backup and recovery industry.  It has literally every feature that you’d expect in top notch backup software.  And the best part is it’s free.  Unfortunately, the system recovery doesn’t work from USB drives.

  • Free
  • One-click system backup
  • Lots of options


  • Buggy system recovery
  • Needs add-on software to accomplish simple tasks

The Bottom Line

Comodo Backup has a lot of potential, but until the bugs are worked out I can’t recommend it.


The installation of Comodo Backup is fairly easy.  You just have to select your language, accept the license agreement, and choose where to install.  The installer will also activate a free lifetime license.  The computer will need to be restarted to complete the installation.

Backing Up

Finally, a true one-click backup solution.

Upon clicking “System Backup”, Comodo will analyze your attached drives, and automatically back up your entire system!  Not even True Image is that easy.

Comodo Backup...backup complete

Comodo Backup can backup your entire hard drive.

If you just want to back up files and folders, Comodo Backup can do that too.  It also supports backing up registry entries, email accounts, and even IM conversations.

Unfortunately, Comodo Backup needs add-on programs to accomplish simple tasks.  Want personal tech support?  You’ll need Comodo’s Geek Buddy software.  Want to create rescue media?  You’ll need Windows Automated Installation Kit.

Microsoft states “To install the Windows AIK, you must first download the ISO, Write the ISO file to a DVD using a third party tool, and then install the Windows AIK from the DVD.”  That’s a lot of work!


The good news is that once you create rescue media, you won’t have to do it again.  You’ll only need this in case your entire system crashes and you can’t boot.

I was unfortunately unable to do a system restore due to the error “volume(C:) is busy or access denied and could not be locked.”  I tried using both a recovery DVD and the desktop software, but it just didn’t work.  I even tried to schedule a restore at the next boot, but it can only restore from an internal drive (I was using a USB drive).

If you just want to restore a file or two, you’ll need to mount the existing backup as a drive (under Manage > Mount existing backup).  You can then copy files and folders from the mounted drive.


Comodo Cloud

Comodo Cloud is an online file storage service.  You can backup your files to this secure storage and even mount it as a drive.  The best part?  It comes with 5GB free and is completely integrated into Comodo Backup.

Full System Backup

Comodo will backup your entire hard drive, boot record and all.

Incremental Backups

Incremental will back up only the changes since the last backup, saving you precious hard drive space.

Windows Explorer Integration

If you want to, you can right click on files you want to back up right from Windows Explorer.


Backup just your browser data?  Just your email?  Or maybe you only care about your music?  Comodo Backup has pre-made, one click profiles for many common backup tasks.


The manual is quite extensive.  Comodo Backup has a lot of features, and it goes over each one in great detail.  Paid support is provided through Geek Buddy, a $50/year service that Comodo created.  They will try to fix any computer problem (not just for their products) using remote desktop and your internet connection.  There are no limits on how often you can use your Geek Buddy.

@FabacusSuite Just noticed your tweet! I’m not aware of any cloud storage needs specific to manufacturing. I’m open to insight/suggestions. – 3 weeks ago

    I love Comodo products, but this backup tool is complicated, confuse and the online help is not help at all…. maybe if I invest more time I can manage it, but I prefer something easier
