The world backup day is an initiative to make people aware on the importance of backup. The official website of World Backup Day is at http://www.worldbackupday.com/en/ Your hard disk, smartphone or laptop may not be always loyal to you. Computers get infected with viruses, smartphones are lost and your hard disk gets fried. “Remember backup is a continuous process not a one off process. You must always backup your data not only on 31 March.” WHAT IS BACKUP? Let’s quote exactly from the website: A backup is a second copy of all your important files — for example, your family photos, home videos, documents and emails. Instead of storing it all in one place (like your computer), you keep another copy of everything somewhere safe. WHY SHOULD YOU BACKUP ? Your data is valuable. It’s important because you might need it for personal and professional reasons. Your ebooks, your final year dissertation, your source codes, your customer list, your chi...

The following has been taken from  VMware Knowledge Base  -  KB 1025279 Snapshots are not backups . A snapshot file is only a change log of the original virtual disk. Therefore, do not rely on it as a direct backup process. The virtual machine is running on the most current snapshot, not the original vmdk disk files. Snapshots are not complete copies of the original vmdk disk files. Taking a snapshot does not create a complete copy of the original vmdk disk file, rather it only copies the delta disks. The change log in the snapshot file combines with the original disk files to make up the current state of the virtual machine. If the base disks are deleted, the snapshot files are useless. Delta files can grow to the same size as the original base disk file , which is why the provisioned storage size of a virtual machine increases by an amount up to the original size of the virtual mach...

About 5 minutes ago I found a nice freeware tool ( InstalledDriversList ) which can be used to view the installed drivers on your PC. From the official website of InstalledDriversList : InstalledDriversList is a simple tool for Windows that lists all device drivers that are currently installed on your system. For every device driver, the following information is displayed: Driver Name, Display Name, Description, Startup Type, Driver type, Driver Group, Filename, File Size, Modified/Created Time of the driver file, and version information of the driver file.  If the driver is currently running on Windows kernel, the following information is also displayed: Base Memory Address, End Address, Memory Size, and Load Count. This tool may be used to identify which drivers are causing trouble on Windows. Again quoting the original text: Green Icon - The driver is running on Windows kernel. Yellow Icon - The driver is not running on Windows kernel. Red Icon - The driv...
