Want a backup strategy that backs up everything on your PC? Considered cloning—your hard drive, that is.

For backing up data, there's no shortage of  alternatives to choose from. Few, however, are as simple and  straightforward as simply cloning your hard drive (http://www.pcmag.com/reviews/hard-drives).  If you need to copy all of your data, or want to safeguard against a  corrupted or physically damaged hard drive, having a functional copy of  the drive you can immediately turn to is hard to beat. And unlike some  backup strategies, which require regular attention or convoluted tools,  cloning a drive is a relatively uncomplicated affair.

Two Options: Clone or Image

A clone is a direct copy, bit for bit, so that the data stored on the  cloned drive is identical to the data on the original drive. From the  operating system to the hidden directory files, from your desktop to the  device drivers, everything is copied identically. Swap the old drive  out for a freshly made clone and there should be no functional  difference. You can also use the cloned drive in another PC, and aside  from some potential missing drivers due to hardware differences, it  should work just like your old system, making it an ideal backup in the  event of a damaged PC. The downside to this, however, is that a direct  bit-for-bit clone will usually be the only thing on the backup drive.  

   The second option is to create a disk image, which is a snapshot of the  drive data; it still creates a complete copy of the drive contents, but  it does so in a single compressed file. It's sort of like copying your  entire drive to a big .zip file. You can actually back up more than one  image, letting you save the entirety of your drive multiple times and  different points in time, and save them locally (to a backup partition)  or onto a separate drive. The downside, however, is that the image isn't  immediately functional. For an explanation of how to create and use a  disk image, see "The Beginner's Guide to PC Backup (http://www.pcmag.com/article2/0,2817,2363057,00.asp)".

Tools and Utilities (http://www.pcmag.com/category2/0,2806,4833,00.asp?source=linksmart0405&lc=int_mb_1001)

For those who want to clone their drive directly, there are several  tools available. Among the many backup utilities we've reviewed, our top  pick is Acronis Backup & Recovery 11.5 (http://www.pcmag.com/article2/0,2817,2366426,00.asp).

  It's an amazingly thorough and powerful backup application, more  suitable to expert IT managers than for small businesses or consumers.  It can do just about anything, but you should need to read a  downloadable manual to use some of its features.

   While many find it worthwhile to pay for the convenience and ease of use  offered by a for-purchase program, there are a few popular free  alternatives that may do the job just as well, such as Macrium Reflect Free (http://www.macrium.com/reflectfree.aspx), ShadowCopy (http://www.runtime.org/shadow-copy.htm), Clonezilla (http://clonezilla.org/), and EaseUS Todo Backup Free (http://www.todo-backup.com/products/home/free-backup-software.htm).

Destination Drive

Cloning a drive, or even saving a backup image, requires having  someplace to save your data to. When backing up an entire drive, you'll  want to have a drive of equal or larger capacity set aside for backup,  and nothing else. You have to real options: A bare hard drive, or an  external drive.

   A bare drive is exactly like the drive you already have in your laptop  or desktop—it's the actual drive, but not yet installed in a machine.  Once you've acquired the drive, you can either install it as a second  drive or purchase a compatible drive enclosure for it. These drives come  in several physical sizes, meant for desktops or laptops, and both  spinning hard drives and solid-state drives (SSD) are viable options.  For cloning purposes, you'll want a drive with at least as much memory  as the data you're cloning (the amount of used memory in the original  drive). For example, if you only have 200GB of data stored on a 500GB  drive, some cloning tools will let you clone the data to a drive smaller  than 500GB, so long as there is space for all 200GB of data. For a  drive that can literally be swapped for the one already in your PC,  you'll definitely want to get a drive that is the same size and  connector type as the original. For a more in depth explanation, check  out "How to Buy an Internal Hard Drive (http://www.pcmag.com/article2/0,2817,2382325,00.asp)".

   The other option is to buy an external hard drive. These are  self-contained drives, usually connected through a USB connection.  External drives may be larger deskbound drives or pocket-sized  portables, but they generally all will work as a suitable backup medium,  and many will also offer additional features, such as encryption or  automated backup software. For a detailed look at desktop and portable  drives, check out "How to Buy an External Hard Drive (http://www.pcmag.com/article2/0,2817,2358135,00.asp)".

  Clean Up Your Files

With both a backup utility and a drive to back up to, you're  ready to clone your drive, but this is also a good opportunity to do  some digital spring cleaning. There's plenty of data you want to back  up, but chances are you also have plenty of stuff saved—drivers for old  devices, programs that aren't needed, media files you couldn't care less  about—that doesn't need to be duplicated. For a great guide to getting  your drive in tip top shape so that you aren't cloning a disorganized  mess, check out "Get Organized: Keep or Delete? (http://www.pcmag.com/article2/0,2817,2415505,00.asp)".

  Making the Clone

Once you've got your back up drive, cleaned up the digital detritus, and  figured out your backup utility, it's time to start cloning. Connect  the destination drive, open up your backup utility, and follow the  utility's directions to copy the contents of your hard drive to the  backup. Depending on the size of the drive to be cloned, the amount of  data stored on the drive, and the speed of both the original and backup  drives, this process may take anywhere from several minutes to several  hours.

  Caring for Clones

Once the drive is completely cloned you're done—for now. What you have  is an exact copy of the original at that moment in time. Any future  changes in files, programs, or anything else will only be reflected on  the original drive. Once you swap it for the clone, it will be like  stepping back in time to the day you cloned the drive originally. For  more up to date backup, you'll want to schedule time to make a fresh  clone at regular intervals—even if it's just an annual copy for World  Backup Day (every March 31st).

   You also want to keep that cloned drive somewhere safe and accessible.  For long term storage you'll want to be especially careful to keep the  drive safe from moisture, extremes in temperature, and static  electricity or powerful magnets. A safe bet is to slip the drive into an  anti-static bag and then store it the same way you would vital  documents—in a safe or fire box. If you're less concerned with immediate  accessibility, you might also consider storing the drive off-site so  that you have a backup to turn to in the event of fire, flood, or  similar disaster.
