hi, about a year ago I bought a laptop, last week is started to play up, rang the maker and they said the would pick it up and have a look, they came next morning, I was delivered back to me yesterday, now to the point....I have all the disks for reinstalling everything, well, i did till i got it back.....all the progs now have all the latest versions in there, plus bits i have no idea about and the bios thingy is totally different....is there anything out there that i could buy so that the whole lot could be put on a external HDD inc the OS..then if the need arose I could put it all back like it is now.
The ideal situation is to create a image of the drive, you could do this now with the clean machine and retain it if ever you wanted to get back to this same position. In addition you would be wise to create periodic images as your working backup.
It is much safer to create these backups on a seperate drive or device.
I think they are using the term Online to mean the PC (well the disk) is still on and operational whilst you are backing up (well Imaging) the PC. As oppossed to an offline where the disk has to be stopped and imaged.
It doesn't mean backing up on the internet or anything like that.
