Backup of open/locked files failes

Help - CB
1

Hi,

I am just trying Comodo Backup. What I saw until now is really good :slight_smile: Great work!
By now I was using Acronis True Image Home to backup my files.
No doubt its a great program, but it always bothered me with errors when encoutering open files.
For that reason I gave Comodo Backup a try.

Now I have set up a backup task to test the VSS-funtionality. Unfortuantely it does not work. Raw read does also not work.
I am trying to backup a *.pst file from Outlook 2007 while Outlook is opened and accessing the file.
Acronis always threw an error on that file, but Comodo just seems to omit it.
No entry in the log file and no data is being backed up.

What am I doing wrong?? I’m using Windows 7 Professional x64.

Thank you in advance an best regards
Mark

Hi

Please let me know if I am correct:
You selected a single *.pst file (in backup step 1), in backup step 2 you chose the destination then you clicked backup now without changing other settings?
Did you get error 92 (no content) during backup?

Thanks

Dear Emanuel,

right. I select a single *.pst file in step 1.
Then I set a local destination (CBU-Type), change the compression to maximum, CPU utilization to low and click backup now.
The log looks like this:
08.02.2011 18:54:59 Creating New Backup…
08.02.2011 18:54:59 Creating full backup “E:\Backup\xx@web.de_full_files.cbu”
08.02.2011 18:54:59 Collecting information…
08.02.2011 18:54:59 This might take a few minutes depending of the number of files and folders…
08.02.2011 18:54:59 Writing initial items information…
08.02.2011 18:54:59 Writing items content…
08.02.2011 18:54:59 Processing D:\Eigene Dateien\xx@web.de.pst
08.02.2011 18:54:59 Writing indexation…
08.02.2011 18:54:59 Items backup is complete.
08.02.2011 18:54:59 Backup Process Complete

The final CBU is about ~2kb. The *.pst-file is 450mb.

This only happens when Outlook is accessing the file.
When I close Outlook everything works as expected. But Outlook is opened most of the time on my pc.
Like I said, raw read also does not work.

Greetings

Unfortunately this log is not very helpful.

It would be more helpful if you could create a dump file using steps here: How to collect debug information - News / Announcements / Feedback - CB - Comodo Forum.
Also, please let me know if you restore the *.pst file to another location, what is the size of the .pst file?

Thanks

Hi Emanuel,

here is the Debug.CBU.

I hope this helps.

Thank you for the Debug information.
CB can’t access the file because Outlook has locked a portion of the file.
We will fix this in the next release.

Thanks

Hi Emanuel,

thank you for your promt support.
Can you explain whats the problem? I thought that CB can backup locked files via VSS?

VSS is used only when a file is determined to be locked.
There is an issue with the way CB is determining if a file is locked.
CB tries first to access the file as normal file (unlocked). It seems to work.
Then CB continues to back up content. Here it fails.

The issue will be fixed this in the next release.

Thanks
