No. You need to do it manually.
Use an external harddrive. (USB stick is most common)
An external hard drive can be expensive and easily damaged or corrupted. It can however be useful to back up computers, easy to transport, and easy to use.
back ur files up on a memory stick or a external hard drive
by deleting unwanted information from your harddrive you increase the amount of available memory by the size of the files you deleted.
With an external hard drive =D
I recently bought a 250GB external drive. The brand is 'Transcend'. It works great. These external drives do not automatically do anything on their own. You need to tell your system to do the backup.
Wipedrive erases data by deleting the files off your harddrive and cleaning all of it out and it pretty much resets your computer back to when you first got it.
No, there is no need at all, unless you want to be doubly sure.
Because files are temporarily stored in RAM, which is volatile and requires a constant power supply while in use, when being moved, they are not safe from power cuts and emergency shutdowns. Unless you had them backed-up on another harddrive or disk system, unfortunately, you cannot get the files back.
Time Machine is software that will automatically back up and catalogue everything on your Mac's hard disc. You can then use Time Machine to find copies of files, from the back up disc, that may have been deleted, lost or damaged. Time machine requires an external drive to back up to and needs to be switched on from the Time Machine section of System Preferences.
Windows 7 Professional can utilize any connected hard drive to backup files. You can also back up to DVD. And the Professional or Ultimate editions of Windows 7 will also have the option of backing up your files to a network.
no.
