FileSlinger™ Backup Reminder 03-03-06: Unreliable Backups

Friday, March 3rd, 2006
Vindication is a bittersweet thing. For years, the Ur-Guru has told me, and I have told clients and readers of this column, that backing up the Windows operating system from within Windows is a Bad Idea. Copying any file while it’s in use makes it more likely the copy will be corrupted in some way, though it usually works all right with ordinary documents and images, at least if you’ve saved any changes. Software is something else again. These days most programs install bits of themselves all over your computer, and you can’t just drag the .exe file onto another disk and expect it to work. And I can’t speak for Linux, but the Windows and Macintosh operating systems are now extremely complex beasts.

This is why I prefer Symantec (Norton) Ghost 8 for my full system backups. Ghost 8 runs in DOS. That means that Windows isn’t running when you use Ghost 8 to back up, which in turn vastly increases the reliability of the backup. I’ve restored machines from Ghost backups many times with complete success. The only hitch was that it was designed to be run from floppy disks, and modern laptops rarely have floppy drives. Oh, and it didn’t always want to recognize USB or FireWire external drives, though I had no problems with my FireWire XHD on my previous laptop. (My current laptop doesn’t have FireWire.)

When Ghost 9 came out after Symantec bought DriveImage, I didn’t upgrade. DriveImage had a good reputation, and I recommended it to clients without floppy drives (prior to the new Bart-PE CD which runs Ghost 8 but is, shall we say, somewhat ethically complicated), but I didn’t want to use a product which tried to back Windows up from within Windows, and that’s what Ghost 9 is. (The Ur-Guru wrote me paragraphs of outrage when he tested it.)

Why am I bringing up all this history? Because IntroAnalytic just released a new study involving DriveImage (the pre-Symantec product), Norton Ghost 9 (whether Ghost is billed as “Norton” or “Symantec” seems to depend on whether it’s the consumer or the corporate version), Acronis TrueImage 7, and Microsoft System Restore. System Restore (which has actually been useful to me in the past) rated the lowest: IntroAnalytic gave it 0%. But of the third-party products, Ghost 9 came out at the bottom, with only a 75% chance of successful recovery from a major computer error (non-functioning OS). Drive Image came out on top, at 90%.

They didn’t test Ghost 8, presumably because their aim was to compare products which operate from within Windows and work with external hard drives. They also didn’t test Dantz Retrospect, but I found Retrospect decidedly underwhelming anyway.

Where does this leave someone just embarking on a backup plan? In an uncomfortable position, given that Drive Image and Ghost 8 are no longer sold by the manufacturers. In order to get the most reliable software for making a full system backup, you have to go hunting around on eBay and other places where used software is sold. If you can’t use diskettes or just need to be sure Ghost 8 will recognize your external drive, you then have to create a Bart-PE CD (or get someone like the Ur-Guru to create it for you).

And remember—whatever backup software you use, you need to test your backups. If you can’t bear to take the plunge and do a test-restore of your whole machine, try restoring one or two files. This will at least assure you that the image is not corrupt. (One drawback of Ghost is that if you span a Ghost image over CDs or DVDs, a single damaged disk renders the entire image unrecoverable. I learned this the very hard way.)

FileSlinger™ Backup Reminder 5-6-05: The Ghost of a Chance

Friday, May 6th, 2005

After three attempts to repair the power-connector problem with my laptop (and then-only computer), I realized that I would need not one but two computers to replace her. New computers come with warranties, which is good—but to have repairs done under warranty usually means sending the computer back to the manufacturer, which takes a week to ten days, and is NOT good. So I needed not just to back up the data on my machine, but to get a backup machine to use in case something went wrong with the first one.

With a little research and the help of Craigslist and eBay, I was able to purchase two computers with my new-computer budget: a brand-new 15.4″ widescreen Gateway, and a used Dell Latitude PIII with a year still remaining on the on-site service contract. The Gateway is still being assembled and shipped, but I picked up the Dell last week and have been busily installing and configuring it.

One thing about new laptops which I don’t much like is that they don’t have floppy disk drives. True, almost no one uses floppies these days, but a floppy drive is a requirement for using Symantec Ghost 8 Corporate, my preferred drive-mirroring program. You create the floppies from within Windows using Ghost Boot Disk and then use them when making or restoring from backups. They run an operating system called PC-DOS and can thus create an image of your drive when Windows is at rest. When Windows is running, something is always changing, so the chance of an error when creating an image is much too high for my comfort. I’d used Ghost 8 with great success on Keramat (the dying computer) and would prefer to go on using it.

Last year, however, Symantec bought PowerQuest, the makers of DriveImage. The good news is that Ghost 9 does not require a floppy drive. The bad news is that it makes its backups from within Windows. This made me nervous. And while PC Magazine and other reviewers gave Ghost 9 good marks, the Ur-Guru panned it—primarily because it couldn’t recognize his RAID controllers and was therefore totally useless to him.

So I was happy to discover that Astarte came with a floppy drive, the kind you swap with the CD drive. I figured I was all set to go on making backups with Ghost 8, at least on my backup machine.

But for some reason Ghost 8 can’t see my external hard drive when I connect it to Astarte’s USB port. (Astarte doesn’t have a FireWire port, one of her few drawbacks.) It can’t see my CD/DVD-writer, either. It seems to be blind to USB, despite the fact that I had it install USB drivers when I made the floppies, and despite the fact that Astarte can see and use both external drives just fine from within Windows.

This meant I had to use Ghost 9. Since I didn’t want to put a full installation, much less my own data, at risk, I decided to test it on the bare system as I’d bought it. (And I was annoyed to discover that while you can restore from the Ghost 9 CD without starting Windows, you can’t back up directly from the CD. What were they thinking?)

To my relief, it worked just fine, but I still don’t feel entirely satisfied, and I’m going to want to test out some alternatives once the Gateway (whose name, incidentally, is Enheduanna) arrives. It may be that I’ll prefer Retrospect, TrueImage, or another program to Ghost now that I’m entering the floppy-free zone.

FileSlinger™ Backup Reminder 9-10-04: Ghost 9

Friday, September 10th, 2004

Dear FileSlinger™ clients, colleagues, and friends:

It’s Friday again and time to back up your data.

I’ve made more backups than usual this week because of reinstalling my computer to put Windows XP Service Pack 2 on. I’ve saved copies of my drive at various states of installation, in case something goes wrong, so I don’t have to go all the way back to the beginning and start over. These interim backups can save hours. If you have someone reinstall your operating system, or you do it yourself, make sure you, or the consultant, makes some of these on the way. That will mean less consultant time you have to pay for, or less of your own valuable time that you have to lose, the next time something goes wrong with your drive.

It’s true, having even a very new computer is much like having a very old car—things just keep going wrong. This is in part because many software manufacturers (Micro$oft is not the only guilty party) charge us good money for products that aren’t really finished and which interact with each other in unpredictable ways. This is very frustrating, but short of the entire planet refusing to use computers until they are more reliable, there is probably not much to be done about it.

Today I wanted to talk a bit about one of those unfinished programs. Symantec/Norton (makers of an antivirus program which can be worse for your computer than most viruses) has just released Norton Ghost 9.

I use Norton Ghost 8 for making my full-system backups, and I love it. Its only drawback is that it really isn’t designed for computers without floppy drives, and the workarounds for that are a trifle clumsy.

Last year Symantec bought PowerQuest, makers of DriveImage, a highly-rated competitor of Ghost’s and one which uses a CD rather than a floppy disk for recovery.

This year it appears Symantec has combined the worst of both programs to produce Ghost 9. The Ur-Guru tested it out and found huge problems. For one thing, it won’t work on anything with less than 256 MB of RAM. For another, it’s in such an unfinished state that Norton is shipping Ghost 8 along with it.

So if you use Ghost 8 and get an upgrade offer—DON’T.

On the other hand, if you don’t have a backup system in place and do have a floppy drive, now would be a good time to buy Ghost 8, while you still can. It’s likely to be moved to the discount remainder bin soon, so you’ll get a good deal on a much better product.

Once again, if you’re a Mac user, this information won’t have been very useful to you. I need your help to provide Mac-friendly reviews, until I can get a Mac of my own and be a two-platform family again.

But whatever kind of computer you have and whatever kind of backup system you have—make frequent backups of your data. Replacing hard drives and software only takes time and money. Replacing your data can be impossible.

And remember—if you’ve got your backups automated or for some other reason don’t want to receive these reminders, just e-mail me and let me know, and I’ll take you off the list.

If someone you care about needs a backup system—don’t wait. Send them to me right away.

More backup news next week,

Sallie
