COMODO Backup 4.1.4.0 Bug Reports

[FBTFQYCS]

@Emanuel Sescu post:53

From the log file, it seems that the install path for “Outlook 2003” could not be determined. Unfortunately I can’t provide more details because the debug data in debug.cbu is too old. debug.cbu was created six and a half hours later after the error occurred, and it was overwritten since the debug logs have a size limit.

I can provide more info if the debug information would be collected exactly after the error occurs.

Thanks

Hi Emmanuel

I have sent you a PM containing a link to the debug info. This was collected shortly after the CBU backup of my Outlook folders. I have also included the relevant portions of the CBU log file

[emanuels]

Thank you for the debug logs. We found the cause. The issue will be fixed in next release.
Running backups as service mode is causing the issue. This error can happen with any email/messenger client backup job. Until then, you can try to use other run modes.

Thanks

Thanks very much. You diagnosed that one very quickly.

Hi,
CB 4.1.4.0 (and 4.1.3.51 too) shows a bug with incremental backups with respect to Snapshots.

The case is:

1. I backup the folder A, with file 1 and file 2, from a saved profile.
2. The first back is full, resulting in Snapshot 0.
3. Then I delete the file 1 and add another file: file 3.
4. I run the backup, resulting in Snapshot 1.
5. I load Restore for that profile, and in Snapshot 1 there are all files to restore, that is file 1, file 2 and file 3.

In snapshot 1 should appear only file 2 and file 3 because file 1 was deleted before Snapshot 1.
However, when the backup is working, the description is correct, for example “…deleting file 1…”.

It will be interesting that the snapshots only show the folders and files that were present when the backup task was loaded. It seem to be that each snapshot is accumulative, showing all files and folders. I thought the idea with CB was to have a “timeline” folder and files versions.

Thanks.

(Win 7 Professional 32 bit; laptop HP430; CB default configuration)

Yes, it’s a known issue in CB 4.1
It will be fixed in next release.

Thanks

Whenever Comodo Backup (4.1.4) is running, even if it is minimized or I switch over the Windows 8 start screen, the screensaver will not work. It is set just to turn the monitor off after 10 minutes and works fine as long as Comodo Backup is not working. As soon as Comodo Backup starts, the monitor is turned on and stays on as long as the backup program is running.

Your Operating System (and whether it’s 32bit/64bit): Windows 8 x64

• Other Backup & Security Software Installed: Comodo Internet security Complete 2012
• How you produced the problem: Everytime Comodo Backup runs

[emanuels]

Hi,

Strarting with next version (4.2.1), CB will no longer require the display for backups that are set to run in silent mode or service mode.

Thanks

[canolradd]

I’ve related some problems with CB in https://forums.comodo.com/help-cb/maybe-cb-is-somewhat-immature-t87784.0.html;msg632966#msg632966.

Please see attached file.

Any help will be appreciated.

I think you are referring to the mount issue.
The logs have information starting from 18.Oct.2012 to 25.Oct.2012 .
Can you remember exactly when the issue happened? It seems I can’t find anything mount related in logs.

Thanks

Indeed.

Sorry, the mount issue is somwhat old. I reproduced it today. The new logs are attached.

We found a potential cause that was fixed.
Please place the proper GUI.exe file below in the installation folder, then run it as administrator and try to mount again (from Manage → Mounted drives).

GUI.exe (32 bit)
GUI.exe (64 bit)

Thanks

Thanks Emanuel, but I couldn’t run GUI_x64_3rd_dec_2012.exe. My system complains that it lacks LIBEAY32.dll. I’ll try to fix this. Any tip will be welcome.

By the way, shouldn’t the installers you’ve recommended be included in Defense+ trusted list?

[emanuels]

Did you try to run it from installation folder (C:\Program Files\Comodo\Comodo Backup) ?
These are not installers, but replacements for CBU.exe

Thanks

Forgive me, Emanuel. I had misunderstood your instructions. Ok, I’ve just run it from C:\Program Files\Comodo\Comodo Backup. It runs ok, but the mount operation gets the same error: Windows Explorer tries to open the “mounted” drive and says that it doesn’t exist.

I don’t know wheter it will help, but the new logs are attached.

According to the logs :

[04.12.2012 13:53:59:019|001856|000012e4|InitMountThreadBody] Browse: SetInitializationInformation failed with status :8
[04.12.2012 13:54:04:215|002099|00000a64|CManageDriversDlg::MountWithDefaultOptions] AskForPassword failed with status: 62

[04.12.2012 13:54:17:272|020409|00001328|OpenExistingBackup] __internReadBackupHeader failed because 8
[04.12.2012 13:54:17:272|000515|00001328|_BACKUP_RESTORE::SetInitializationInformation] Opening E:\teste.cbu error 8

Error code 8 means invalid password or invalid backup file.
Error code 62 means the operation has been cancelled by user.

To translate what happened, according to logs:

1. CBU tried to open the selected backup file (“E:\teste.cbu”)
2. It returned invalid password (because no password was provided yet)
3. CBU tried to request a password from user, the operation was cancelled (error 62)
4. The mount operation failed with error code 8

Is the backup password protected?

Thanks

The backup is password protected. But I did not cancelled. And my password is not wrong, I’m sure. Even so, just after my last post I thought that I should check whether it could be a password (or encryption) related issue. So I created a partition backup with no passoword at all. Even so, I got the same error. ???

Just now, I’ve done the same:

• created a fresh partition backup, with no password and no encryption;
• tried to mount it; a progress bar is shown; when it completes, a Windows Explorer window opens with no content and an error message is issued (“f:\ refers to an unavailable local. etc.”);
• CB keeps showing the path and name of the “mounted” backup as an entry in the list of “Mounted Drives” tab;
• the entry stays blinking as if CB is stuck within some processing;
• finally, I click the button “Unmount” on the right end of the entry (maybe this is the “cancel” user action?)
• the supposedly mounted drive is “unmounted”.

The logs follow attached again.

I have some useful news, I hope. Yesterday, I finally got time to try one thing: log on to my computer as an administrator and try to mount a .cbu backup. Success!

By the way, CBU.exe and GUI_x64_3rd_dec_2012.exe behaves slightly different, but both mount the drive as expected. However, the former shows the .cbu file as not mounted yet, even after mounting it successfuly.

So let me add a detail in my scenario: I’m always logged on as a restricted user. When needed, I “runas” administrator CB or any other application. So the mount operation fails in this scenario. Anyway, this is the scenario where I work everytime. Can this issue be fixed?

Any clue will be appreciated.

I’m curios about disk backups (not partition, but entire disks), are they visible when mounted using “run as” administrator?
If yes, I think the issue can be fixed.

Yes, they are mounted and visible with no problem! A surprise to me, since my previous tests were with partition or folder backup.

By the way, testing this flawed scenario for the n-th time, I found an interesting thing. As I’ve said, when I click the “Mount” button, I get the error message from Windows saying that the drive doesn’t exist. Trying to mount another .cbu file, I clicked the “Browse” button and found that the mounted drive was visible inside the “Open” dialog, that is, in the same (runas administrator) context of CB. Even so, the mounted drive doesn’t appear for another application, even when the latter is run as the same administrator. Nor does the drive appear for that administrator if I switch the user session for one where that same administrator is logged on.

I hope that such details can be useful.

[emanuels]

Yes, the information is usefull. It will help us in implementing a fix for the issue.

Thanks
