Online backup for personal computer

For a while now I have been trying to persuade myself to start using an online backup service for my private documents, pictures, emails etc. The thing is that over the years I have, like most others I guess, built up quite a lot of personal data which it would be impossible to recreate should it be lost.
Until now I have backed up data to from the laptop to an external USB drive. This method works smoothly with the built-in backup software on the USB drive from Seagate. And I will be able to restore data should the disk fail or if I lost the laptop. However, for the most part the external disk with the backup data was, and is, lying just next to laptop. So in case of a break in, a thief would most likely take both the laptop and the usb disk. Or in case of a fire or other such extreme cases both laptop and backup will be lost. The risk is small but the impact, from my personal perspective, is rather high.

After looking online backup I found the following things which was reassuring:
Online backup seems to be a relatively mature market. There are quite a few players, and prices seem competitive. A one year subscription ranges from 50-100 US$.

Security seems to be in adequate . Most providers encrypt data before, while, and after it has been uploaded. Unfortunately, encryption is only protected by password (at least for the solution that I chose) so it's not this double security approach where it's something you have (like a RSA token or PKI) and something you know (the password). However, for my chosen solution, I first have to log in, and then I have to provide a strong password, which is not stored at the service provider, to acutally restore data.

Of the bigger players can be mentioned IDrive, Mozy, Carbonite, Crashplan, and BackBlaze. I read a few reviews and it seems that, a part for some minor differences, they offer pretty much the same service, so one should be pretty safe to choose either one of them.

Here's link to two reviews: From Notebook Review and from Digital Inspiration

I was leaning towards Crashplan mostly because the interface appealed to me and a colleague recommended it. However, I ended up choosing IDrive for the following reasons:
  • It's been around for longer than the other players (you don't want your backup provider to go out of business).
  • Phone support (when trouble hits it's always nice to be able to call someone...)
  • Price was right for my needs (50 US$/year for one computer and 150 GB storage)
  • Online browse and restore of files
  • Continuous backup and file versioning
  • Sufficient security
  • Status reports via email
My experience after a weeks use is that maybe it is not the fanciest of interfaces, b
ut it gets the job done. After three or four days I had uploaded my ~25 GB of data over the ADSL connection and I have tested restore of files from the web interface successfully. And email notifications work.


On a final note I can mention that I have been using Dropbox for a while to be able to share files between computers and to be able to reach files online. It's limited to 2 GB in the free edition but it can be highly recommended. It supplements the backup application but it cannot substitute it in my opinion.

How to Back Up the Registry & Restore the Registry


Back Up the Registry

Before you edit the registry, export the keys in the registry that you plan to edit, or back up the whole registry. If a problem occurs, you can then follow the steps how-to restore the registry to its previous state.

How to Export Registry Keys
Click Start, and then click Run.
In the Open box, type regedit, and then click OK.
On the File menu, click Export.
In the Save in box, select the boxs at the bottom the bottom according to weather you want to export all or only selected branches of the registry.

The Five Kinds of Computer Backup Storage

There are five kinds of computer backup storage each with its own advantages and disadvantages you should consider. We’ll briefly describe each type of computer backup storage in this article so you can choose the best option for you. I have definitely learned the hard way, over the years, about the importance of backing up files. Many times I thought my files were safe and secure when they actually were not! I also sometimes just simply forgot to backup all the files and now have a list of the mostimportant computer files to backup.
Computer Backup Storage #1: No Backups
Even a few years ago, it would be crazy to suggest to people that they use computers without making regular backups, but today it’s a very real and very legitimate option. Thanks to the prevalence of “cloud” applications from Google and other companies, many users today store all of their files and applications entirely on the Web.
If you use hosted applications for everything, then you have nothing to worry about when your computer fails. You just need to stand up, walk to another computer, and log in to start working where you left off.
This option isn’t for everyone. Anyone who still needs an offline application or wants to keep their files private from Google still needs to store files locally and should make Easy Secure Backups using the methods described later in this article.
We expect a significant rise in the number of users who store all of their data in the cloud when Google releases its upcoming Chrome operating system for computers.
Computer Backup Storage #2: Same Disk Backups
At first, making a backup to the same disk doesn’t make any sense. If the disk fails, you lose both the original and the backup copies. Plus, making a same disk backup will run slowly—hard drives aren’t designed to quickly copy data from one part of the disk to another part of the same disk.
But a same disk backup can give you access to an important computer backup storage feature: the ability to save multiple versions of the same file. For example, you can make a new copy of your accounting Excel worksheet every time you save so that you can always restore an older version if you make a mistake. You probably also want to do this with important Word documents in case you accidentally delete a few paragraphs or pages, your Outlook email files in case you delete an important email, and many other applications.
Although a same disk can be useful, you should always remember that a disk failure will wipe out both original and backup copies, so this method is best used in combination with computer backup storage methods described later in this article.
Computer Backup Storage
Computer Backup Storage #3: External Backup Disks
External backup disks is one of the cheapest methods of computer backup storage and probably also the method that offers the best privacy for your files. Best of all, external backup disks are easy to use with Windows.
Most external disks these days use USB 2.0, although a few disks use Firewire or eSATA. In any case, all you need to do is plug in your external disk and wait for Windows to load it (also called mounting). After you disk mounts, go to the Windows Backup Wizard located in the System and Maintenance menu of the Control Panel. Set up a backup and start it right away.
You have so many choices when buying an external hard drive to use for computer backup storage.
Your first backup to an external drive will take a while, but your second and subsequent backups will go much faster because Windows transfers only the files that have changed.
After you make your backup, you need to safely remove your disk and then store it somewhere safe. It’s no use to you if the same natural disaster that destroys your computer also destroys your backup. You also need to keep the disk safe from attackers or your private files could fall into the wrong hands. For both purposes, we recommend storing your backup disk in a sturdy fire-proof safe.
Thanks to the low price of disk drives, an external backup can cost much less than any of the Internet-based computer backup storage methods mentioned later in this article.
Computer Backup Storage #4: Network Storage
At businesses and even in homes, more and more people are using Network-Attached Storage (NAS), which is simply disk drives accessible over your local network. NAS offers almost all of the benefits of external backup disks and also Internet-based backups for computer backup storage. Many devices made for small and home offices are also very easy to use.
Similar to external disks, a NAS plugs into your computer—but instead of plugging into your computer directly, in plugs into your network router. You can then create a folder on your computer that stores all the files on your NAS. You can backup files to this folder like normal and you can also share files with other people on your same local network.
Because the NAS is separate from your computer, there’s much less chance it will be destroyed by any calamity that strikes your computer. You can even store NASes in a safe place where they’re resist fire damage and thieves while still connected to the network, providing the ultimate in safety and convince.
Computer Backup Storage With RAID
Another great feature available in higher-end NASes is the ability to use a Redundant Array of Independent Disks (RAID) for extra safe backups. If you use your computer for business and worry about losing thousands of dollars of data to a disk drive crash, a NAS with RAID should be an important part of your computer backup storage plan.
RAID is also available for all full-sized PC computers using a special card called a RAID controller computer backup storage, but this method can require a lot of hassle and unskilled users can easily wipe out all their data by choosing the wrong option. With a RAID-enabled NAS, all you usually need to do put a second disk drive in your NAS, browse to a Web interface, and click a button to enable RAID computer backup storage protection.
Computer Backup Storage #5: Internet-Based Backup
The sudden popularity of Dropbox has brought increased attention to the already-established industry of Internet-based backups. Non-geeks will probably appreciate Internet-based backups the most, as very little setup is required. For example, to use Dropbox, all you need to do is install the Dropbox application, create a Dropbox account, and copy your files to a Dropbox folder. Dropbox will do all of the rest.
Dropbox and Mozy both offer free 2Gb storage and promise better security, but you’re still trusting someone else with all of your most important files.  You can get online easy secure backup that is guaranteed against data loss, however it costs an absolute fortune. Livedrive offer unlimited online storage.
The main disadvantage of Dropbox is that you trust the security of your data to Dropbox. Although Dropbox uses high-security technology, any hacker who ever figures out how to get around it will have access to the private files of millions of customers—and that’s an awfully tempting target. In contrast, if you keep your own computer backup storage, you only need to worry about direct threats against your computer.
Conclusion: You Can’t Avoid Computer Backup Storage
Whether you choose to keep your data in the cloud or store it on a high-end NAS, you should still make a clear choice about how you want to keep your computer backup storage before something goes wrong and your data is suddenly gone. If you organize your computer files neatly you will find that any kind of backup is a whole lot easier!!!

How to Backup / Restore XP Activation

C:\WINDOWS\system32>dir wp*
Volume in drive C has no label.
Volume Serial Number is 8447-0571
Directory of C:\WINDOWS\system32
10/24/2001 08:28 PM 12,584 wpa.bak
01/14/2002 09:05 AM 12,642 wpa.dbl
After you reinstall XP, to restore the Windows Product Activation database files:  
  • Start XP to Minimal Safe mode
  • Change directory to the \%systemroot%\system32 folder
  • Rename the newly created wpa.dbl to wpa.nonactivated and wpa.bak, if it exists, to wpabak.nonactivated.
  • Copy your backed up wpa.dbl and wpb.bak files to the system32 folder
  • Reboot
This should work if you want to avoid activating XP after a reinstall or restore on the same or very similar hardware. It will not work if the hardware is significantly different from that in place when the Windows Product Activation database files were created. This is not a hack to avoid activating installations.

And if you are able to open then at the command Prompt type the following

oobe/msoobe /a or Start/All Programs/Accessories/System Tools/Activate Windows.
