13 Frequently Asked Questions

13.1 How do I uninstall Ahsay Online Backup Manager?

To uninstall Ahsay Online Backup Manager from your computer, just run

%INSTALL_DIR%\bin\uninstall.bat (default location is C:\Program Files\AhsayOBM\bin\uninstall.bat).

13.2 How is data privacy maintained?

All data are encrypted with user's defined encrypting key before they are sent to the online backup server. Without the encrypting key, the backup files are useless to anyone. The backup user is the only person who can decrypt the backup files to reveal the original content.

13.3 How do we backup “Open Files”?

Files should never be backed up while they are open by an application. When an application is running, it stores its data both in system memory and in data files. Backup by copying the data files while an application is running would fail to capture the application data stored in system memory in the backup job. Not only is it backing up less data than what should be backed up, it can also lead to data inconsistency that can finally result in backup files being unusable by the application.

The correct and the only right way to backup an application is to shutdown the application before running a backup job (unless hot backup is supported). When an application is shutdown, it frees all its acquired system memory and flushes all application data from system memory to its data files. The data files now contain everything needed to start an application successfully. Backing up application data files when it is shutdown will guarantee data consistency and backup files recoverability. You can use Pre-Backup command and Post-Backup command to shutdown and restart application before/after a backup operation.

If you really want to backup your files while they are open, Ahsay Online Backup Manager can work with St. Bernard (http://www.stbernard.com/) Open File Manager to provide open file backup support. Please contact us if you need more information.
