Hi,

Please open the Event Viewer from Windows. Do you see any errors/warnings regarding VSS during the backup time?
It seems there is a problem with the Volume Shadow Copy on your computer.

Hi,

Please send me the screenshot and the backup log file to support[at]backup4all[dot]com

Hi,

Is that the only file with problems lately?
If the VSS is working fine and all conditions to back up open files are met, it is interesting to know what application uses that file and if there is any special restriction regarding that file type.

Hi,

Yes, it is if that is working properly.

Hi,

Is there any application using that file over the night?

Hi,

Can you manually copy this file? C:\Ameol2\Data\3w1005.TXT

Hi,

Please send me the last backup log to support[at]backup4all[dot]com.
To find it, go to View->Job Logs->Last backup log.

Hi,

Is this a new backup job or an existing one?
Please note you cannot add files/folders to a backup job created using plugins.
Also please note you press "Add folder" button when you want to add folders, not the "Add files" one.

Do you still have the problem?

Hi,

In Backup Properties, how is the destination device recognized?

Hi,

Please download the latest version of Backup4all 4.8.286 from our website. It includes many bug fixes since the version you have now.
Let us know if you still have the problem after using the new version.
