New to Comodo Backup

In Step 3 Backup Path;
I have chosen c:\comobackup
But it keeps asking for me to
“Provide a valid backup name”
I then type another backup name c:\comobackup\backup1
It asks me again " Provide a valid backup name"
What is a valid backup name and can I use C: as my backup path.


In step 3, there are two tasks you have to perform.

  1. Select the folder the backup file will be stored in
  2. Tell Backup what filename the archive will be stored under.

To complete the second task, provide a filename in the bottom right hand corner of the backup window. The currently selected drive/folder combination should already be there - just add a file name.

Please note, if you are doing a DRIVE backup (as opposed to a FILE backup), you cannot store the archive file on the drive you are backing up (i.e. if you are doing a drive backup of drive C:, then the archive MUST be stored on another drive.

Hope this helps,

Hi Ewen
Thank you for that info…sorted wth that now.
Have read pdf handbook too.
one lst question.
How can I save folder to cd/dvd.
I cant find the folders I created in explorer and there is no disc directory.

Version 2.0 does not have support for backup directly to CD/DVD.
We will add this feature in a further release.

Hi. I"m also new to the program. I have an external drive connected to my CPU and I want to make a backup of the entire c:\ and store the backup on the external drive. The program though doesn’t acknowledge the external drive when I get to step 3 (backup destination); it only shows in the lower window the flash drive I have for ReadyBoost (should have stated I’m running Windows 7 32-bit). What am I doing wrong?



Do you have 2.1 or 2.0 installed?

sorry, 2.1.117500.10

Can you please post the drive letter(s) of the partition(s) of the external hard drive.
What file system do the partition(s) of external hard drive have?

Thank you

My PC setup is as follows:

C: internal HDD Samsung 1TB, one partition, formatted NTFS
D: DVD Drive
E: Kingston Flash Drive used for ReadyBoost
F, G, H, I: 4 removable drives for memory cards (e.g., SD card)
J: external Maxtor drive, connected by USB, one partition formatted NTFS, 120 GB, 114 GB free
K: external drive, one partition, formatted NTFS, 320 GB, 264 GB free

One more question.
If you go to restore tab, is the external hard disk visible?


Yes, all the drives are visible if I switch to Restore. BTW, I tried running the program as Administrator and that made no difference.


Emanuel, any suggestions?



You can type the path manually in the “Save as” edit box, something like “K:\backup.cbu”

We are investigating this issue of missing drive letters.
It will be fixed in the next release (v2.2)


Thanks. I’ll give it a try.

Well, I could specify a backup drive and directory and the program started but showed the “performing backup operation” screen for 20 minutes and nothing on the progress bar at all, so I aborted the operation. Is this normal? I’m only backing up about 55 GB of a new 1TB c: drive.



What version you used for this?
2.1.118414.11 or 2.1.117500.10?


I am new to Comodo also. I am trying to setup a backup from a Network Drive (NTFS) mapped locally unto a directory on my C:\ drive.

So here are some of the drives mapped out:

C:\ - local drive
D:\ - DVD Drive
S:\ - (mapped to) \SimpleShare\NetShare

I am trying to backup data from the S:\ drive onto C:\backup.

  1. Under BACKUPS I select “Files and Folders”
  2. A list of drives appear - but the S:\ drive DOES NOT appear.

From what I understand, I should be able to backup network drives. Am I doing something wrong?


Are you are using CB 2.1.118414.11 ?
If you go to restore TAB, is the “S” drive visible?


I’m hesitating to download and install Comodo Backup.

Presently, I resize my pics and transfer them to an externel USB key (8gig). I also copy most of My documents.

Since my C: is larger then 8 gig is their a Compressing option to backup my C: or the files of my documents ?


Yes, there is a compression option.
You can choose: low, medium or maximum.
You can find it in backup step 2.
