5.  Why Not Just Use File Backups?

I used to use image backups routinely. However, when drives got larger (and when I had so much data on my notebook that I couldn't back up to its drive's other partition), and when I decided that Drive Image no longer met my needs, I began to use Karen's Replicator to do all my backups.

Of course, Karen's Replicator is a file backup system. It is designed to compare individual files on the source and destination drives (or folders), and then to copy a newer file to the destination.

As I discovered (I knew it in my mind, but not in my soul), Replicator copies if the source file is not at the destination. Rename the file? Now, you get the renamed one copied, too, in addition to the original. Rename a folder, ditto. Move a folder into another folder, ditto.

Replicator offers the option to "replicate file and folder deletions" which would solve this, but in barely a week of starting to use Replicator, I learned that this is a bad choice for most people. Replicator even warns against using it. Why? If you accidentally delete a file, then Replicator runs -- and deletes your backup, too!

When I rename files, rename folders or rearrange folders, as far as Replicator is concerned, these become new files. There lies the problem that I've had to face.

Why would I rename files or folders? Answer: For efficiency in finding data. Here's the example: when I originally started

So, the first problem that I ran into, and that I ran into over and over, was that the file backups tended to fill up my destination drive, which was on a computer across my home network.

My recent experience, reinstalling Windows and then copying files to my reinstalled system, has shown me that this duplication of files (via name changes and directory changes) becomes a real pain when I copy everything back to my notebook.

By the way, a couple of advantages of Replicator over copying with Windows Explorer are that (1) Replicator is a lot faster at copying than is Windows Explorer, and (20 Replicator can be

Now, my challenge is to purge the duplicates from the notebook.

For the future, I'll continue to use Replicator for file backups. I think Incremental and Differential backups of whole partitiions are a pain for restoring (or even finding) the latest versions of individual files, while multiple whole partition images will fill a drive quickly. I played that game during the tape backup days. It might be better now, but maybe not.

I haven't gotten into True Image's detailed capabilities, yet, so it may very well keep a catalog on the drive showing all the backed up files and which image contains which version of the files. If it doesn't have this feature, this would be a very logical improvement.

I'll probably set my notebook to do a True Image backup nightly -- and then, the few nights I don't shut down, it will make the image automatically.

6.  My Computer Security Software Recommendations

Anti-Virus

For your anti-virus needs (and, yes, you do have anti-virus needs!) I recommend anti-virus software from Trend Micro (PC-cillin Internet Security, if you want a combination package) or ESET (NOD32, my choice).

PC-cillin Internet Security 2007 (12-months) - Digital - $49.95 - Shopping Cart Link or 36-months - Digital - $89.95 - Shopping Cart Link) offers anti-virus, anti-spam, and firewall for your PC and PDA. TrendMicro provides an easy-to-use product that is from one of the big names in the anti-virus world.

• PC-cillin Internet Security 2007 3-user Digital - Shopping Cart Link
• UK - Trend Micro Home
• Buy Australian PC-cillin Internet Security 2007 - All-in-one Internet Security for up to 3 PCs!

I'm often asked about other several large, popular anti-virus or anti-virus combination packages. Yes, I realize that they are not in my recommendation list, although I could easily use referral links for them, too.

My personal choice is the ESET's small, fast NOD32 anti-virus program, which offers a FREE 30-day evaluation license. I consider NOD32 to be the cream of the crop in anti-virus protection. Unlike some of the others, ESET offers multiple-year licenses also, including updates to the program as well as to the anti-virus signatures.

Read more about anti-virus programs on my web site.

Firewall Software

If you get the PC-cillin Internet Security package above, you are covered from a firewall point of view.

While the Windows XP firewall is much better than no firewall at all, don't count on the Windows XP firewall to meet your needs. You need a two-way firewall, which the Windows XP firewall is not!.

The Windows XP firewall does not control outbound communications originating from your computer — and you should want to have control if adware/trojans/spyware or even commercial products want to talk to the Internet.

Do you want Windows Media Player to call home every time you play something? It does! Do you use the Search function in Windows Explorer to find things on your hard drive? Did you know that every time you search, Windows Explorer talks to Microsoft — I didn't know that when I ran ZoneAlarm, but the Sunbelt Kerio Personal Firewall flags that for me, and I can stop or allow it to happen.

Many other programs call home when you run them, too.

If you don't get either of the above multi-function packages, I recommend my choice for a firewall program is Sunbelt Kerio Personal Firewall. You can try the full-featured "paid version" of Sunbelt Kerio Personal Firewall free for 30 days — after that, you can register it or, if you're using it on a home computer, you can let it revert to the free, lesser-function license. Sunbelt Kerio Personal Firewall is $19.95 for a non-expiring license for the program and includes one year of their updates subscription.

Anti-Spyware / Anti-Adware Software

CounterSpy, from Sunbelt Software, has received many kudos from the computer press for its always-running and periodic full system scans. CounterSpy is my choice for anti-spyware/anti-adware. I use CounterSpy on my notebook (my main computer!), on my wife's computer and on my son's computer. I highly recommend this program.

While I have not recommended any free alternatives, many people prefer to use free products. I have found, purchased and reviewed a very good ebook called Spyware Secrets Exposed about conquering adware and spyware with free software. The ebook also includes three training videos as a bonus.

Anti-spam Software

In today's Internet world, the question is not "if" you will get spam, but when and how much.

I use and now I recommend PopFile as my first choice for handling spam. PopFile sits on your computer, between your email program and your ISP mailbox, and handles emial as it downloads.

PopFile uses a different approach to spam than some other programs — it does nothing to reduce spam. It is designed as an email classification tool — you train it to recognize spam and any other type of email that you want to classify. These classifications can help you sort your emails into appropriate folders in your email program.

Mailwasher Pro is my first choice to handle spam before it ever gets into your computer's Inbox. Mailwasher Pro uses on-line Realtime Black Lists mail servers sending spam recently, "training" by you of what you think is spam, and your own "friends" and "blacklist" lists.

Mailwasher Pro can even bounce spam messages, as if your email address was not valid, although the usefulness and appropriateness of this is questionable. There is s free version called "Mailwasher," but it omits a lot of the functions of Mailwasher Pro that I consider essential — such as previewing the emails safely before they ever get to your email inbox.

Sunbelt Software, who makes the anti-spyware program CounterSpy (which I recommend) and the firewall that I recommend (Sunbelt Kerio Personal Firewall) also has a well-regarded anti-spam program called iHateSpam for Outlook and Outlook Express. Since I don't use Outlook or Outlook Express for email, I haven't tried iHateSpam.

If you use iHateSpam, please write me and let me know what you think about it.

Cable/DSL Router

If you have a cable modem or a DSL modem, you need to have another layer of inexpensive protection between you and the Internet. A cable/DSL router isolates your computer from direct connection to the Internet. Your computer can easily request your email, web pages, etc. through the router. The responses come back to the router and are smoothly routed to your computer. But, someone on the Internet side of the router can not initiate a connection to your computer — they can only respond to your request.

Even if you only have one computer to connect to your cable or DSL modem, I recommend that you purchase and use a cable/DSL router because of the protection it can give you against attempts to attack through some flaws in Windows itself.

A router isolates your local network, whether it is only one computer or several, from the Internet by actually making it a separate network. The router gets the "public" IP address and handles all your outbound communications and the responses to them. But, it blocks computers on the Internet side from being able to initiate communications with your computer! This will prevent you from falling prey to many worms that try to attack security holes in Windows itself.

I've changed my recommended wireless router. A number of friends who have bought WRT54G wireless routers are having occasional "green death" problems — all the lights on the router say it's connected to the cable and to the computers, but they can't get to the Internet without a power-off/power-on on the router.

Why is this happening with this long-respected router? It turns out that Linksys has been keeping the same model number on the router while they changed version numbers. This has been a regular practice with Linksys and was nothing to be concerned about.

But, in this case, with version 5, they changed the router's operating system. Versions 1 through 4 used Linux for its operating system. Effectively, they created a brand new model and gave it the same model number as a frequently-recommended model.

Even more disturbing, they brought the Linux-based router back with a new model number, as if it is the new model.

So, I changed my recommendation to the "old" model — the Linux-based Linksys WRT54GL 802.11g wireless router (Amazon.com or Buy.com ). If you don't want wireless now, or at any time, the function is easily turned off in the router's menu. You may be able to find a wired (that is, non-wireless) Linksys router on sale. If you don't want wireless, I recommend the Linksys BEFSR42 wired router (Amazon.com or Buy.com). Either way, based on my experience, I recommend Linksys routers.
