If I get [some specific backup device], does that mean that I can then
somehow use it to restore my entire machine if it crashes completely?
Yes, butā¦
The device alone is not enough. In fact any device, alone, is not
enough.
Thereās more ā much more ā to restoring a complete system than just having
backups. Besides the device, you need to have taken the right backups, and have
the right tools with which to restore.
]]>
We need to first separate out devices from software.
Devices that appear as hard drives ā be they hard drives or iPods or USB keys or whatnot ā are just that: media on to which you place bits.
Most commonly, particularly with smaller and more portable devices, people copy important files so as not to lose those files should the primary machine go belly up.
In order to do full system restores you also need software that
-
will backup the entire system in such a way that it *can* be restored
-
provide you some way of accessing and restoring that backup when the worst happens
And perhaps most important to realize is that this is typically independant of where the bits happen to be stored.
Tools like Acronis True Image (which I happen to use) as well as others do this.
The first point is handled by performing full and/or incremental complete-system backups on a schedule (though I suppose you could do it on demand). The second is handled by, before needing it, creating a bootable CD that has a copy of the backup softwareās recover tool(s) on it.
You can create bootable USB devices, but this should absolutely be tested prior to needing it, especially if youāre planning to use this backup approach while traveling. (And fortunately, if you havenāt made it before you need it, you also can use another computer to create the bootable media when you find you do need it. Assuming you have another computer available, of course.)
When disaster hits you boot your broken computer from the rescue media, it fires up a restore program which then allows you to locate and restore the backup image from wherever you put it. āWherever you put itā could potentially be an external drive, USB thumb drive or other USB device. (Again, Iād test the device you plan to use to make sure itās recognized by the recovery tool ā not all are.)
Hereās the kicker: the bootable restore tool is almost never the backup image. Meaning, just doing a backup to an external device does not guarantee that you have everything you need to restore it. You need to make or be ready to make that separate bootable media. (I believe that the primary reason for this is the unreliability of being able to boot from random USB devices. Iād never count on my PC being able to boot from my iPod, Blackberry, or Kindle, for example ā all of which might appear as USB disk drives ā even though they might be fine places to store a backup image.)
Summary:
-
backing up data and system are two different things (though the later can supersede the former)
-
backing up system requires backup software
-
restoring your entire system requires
- bootable media for your backup and restore program
- the ability to boot from that media
- the ability for the recovery software on that media to recognize and access the device on which the backup images reside.
When traveling, I do NOT try and backup my entire system.
I do however, backup my data religiously ā which things like an iPod or external hard drive or thumb drive (or Kindle, or Blackberry, or ā¦) are perfect for. In fact, an online backup service might also work, if you have connectivity, and the amounts of data weāre talking about āfitā the bandwidth youāll have available.
One solution is to buy an extra hard disk and clone the original. I use Acronis and āre-cloneā every couple of weeks. This way Iāve always got a totally complete backup. If my original HD dies or becomes completely messed up I can be up and running in a few minutes by plugging in the clone. The only thing to remember is to make sure the power to the PC is off before swapping/unplugging drives. I also backup my data every few days to an external drive.
I make daily images at boot up. Here is how:

I use Paragon ( a complete back-up program),I made a Bootable CD and did A full back-up on my systemā¦ Paragon is not cheap,but for me it worked perfectly,when i had to restore my computer after I had some nasty virus,it worked Greatā¦
One major problem with most backup systems, both hardware and/or software, is you donāt really know if they worked. I have tried all the popular methods, Paragon, Acronis, MS Backup, etc, and I assume they work, but unless you try a recovery, you cannot be certain. This is why after years of various backup methods, I finally settled on Casper. It makes a full copy to a second HD or external HD, all files, even Windows files, and because it uses VSS and VSC, the backup is dynamic and bootable. A file by file indentical copy. Once a month or so, I change the boot sequence in BIOS and boot to the backup, just to make certain itās there and it works. Also, if you lose a file, photo, whatever, you have a instant copy on the backup without having to run any kind of recovery.

Iāve used Acronis True Image for several years, and itās always come through for me.
Iāve had to restore a computer several times. In fact, itās been easier to restore from backup rather than trying to undo some of the ātweaksā Iāve done. Might take an hour to restore, but thatās an unattended hour, where I can just start the restore and come back in an hour to a working computer.
However, now I use Windows Home Server. Didnāt buy it for the backup feature, but that backup sure is nice. Once configured, and itās a simple configure, it backs up every computer on your network. Incremental backups, AND it backs up only 1 copy of identical files, regardless of how many computers the file is on.
With a free add-in, you can even backup the backupsā¦
But whatever program you chose, like Leo says, the most important thing is backing up. Iād also say to have the backup verify the data for every backup. Not foolproof, but better than blind faith. Just make sure you check the log files for any errors.
Finally, every now and again, see if you can restore a file or two from a backup.
Itās like fire insurance: you hope you never need, but nice to have if something does happen.
Iām no techie, and Iām so overwhelmed by backup instructions that Iāve never..gulp!..had the courage to try it. My daughter bought me a 4G thumb drive (or maybe itās called a flash drive; itās the size and shape of a thumb) and a portable 500MG hard drive, but I still havenāt worked up the courage to try a backup. I know I need to do this, but thereās so much more to it than just connecting either one of these to my computer.
1) for full backup instructions, what is the click-by-click sequence?
2) now this article tells me that in case of a crash, this backup alone is not enough to restore anything, and thatās increases my confusion and cowardice in trying a backup
3) I have Windows XP on a 512 machine, and Iām constantly getting messages telling to wait while my computer increases my _____ ? memory (sorry, canāt remember the term) but so far nothing bad has happened. My biggest use of my computer is for email and surfing the internet, though I do a fair amount of work in Word and a little in Excel and very occasionally Corel Photo Shop. In the five or so years that Iāve had this computer, the amount of disk space used and left for use after defragging has barely changed over the years, even though I have stored hundreds of pictures.
There is so much information in your articles that I canāt see which of the methods and steps and software you describe would be the very simplest for this non-tech user. Could you recommend which of your answer(s) would serve me best? Even if you or one of your helpers would just send me the numbers of the answers I could refer to would be a help. Right now Iāve gone through so many of them that Iām on overload and still canāt tell which would be the easiest and most straightforward. Thank you.
