Subscriber Richard Fuller provided some more background so we could understand his preference for backing up to DVD’s.
May respond briefly to your preference for backing up to a removable hard drive rather than a DVD?
While I take on board your concerns about using a DVD for backups, seven years ago I was taught an expensive lesson about the value of backing up to removable discs. The power supply of my computer blew up without warning and cooked everything connected to it.
I lost the lot – motherboard, cards, hard drive, CD drive, Zip drive, and modem. The only item to survive was the cheapest, the 3¼” floppy drive. Fortunately my most important files were still there on the Zip disc, having been continuously backed up until calamity struck.
A removable hard drive or flash drive, if left connected for the purposes of continuous backup, would have been fried along with everything else.
Perhaps this will help to explain why I’m a bit allergic to backing up to anything but a removable disc, despite the potential drawbacks you pointed out in your response to my original question.
I wrote back to Richard to comment:
OUCH! That was a terrible experience. Lightning? or a power surge on the electric system?
Experiences like that, or even malware infections, are some of the reasons that I use an external hard drive to make periodic image backups. I connect the drive, make the backup, and then disconnect it.
If I were to do the “continual backup” process, I’d use a different – and additional – external hard drive, not replace my other backup process.
No, there was no external cause – the power supply just handed in its portfolio and went up in a puff of smoke. Thus your regime of leaving the backup drive disconnected is wise indeed.
Mind you, when I replaced the fan in the PS of this computer a couple of months ago the filth inside was appalling, so perhaps a similar accumulation had created conditions for a fault, even though it had seen a lot less service than the present unit.
