Choosing a Backup Storage Device
It used to be that you would backup everything on your computer by using floppy disks.Today, when one sound or graphics file can easily be larger than the capacity of a disk, it would be impractical to back up even you documents using floppies, let alone your applications. Luckily there are better options including Zip disks, CD writers, tape drives, external hard drives and even online backup services.You can also compress all of your backed up files so that they will take up less space.Follow the following pointers and you will be able to find the media that is best suited to your needs.
1) Determine the approximate quantity and file sizes you will be backing up.
2) Figure out the quantity and file sizes of any documents or other applications you want to archive permanantly to a backup device or removable media.
3) Plan for that amount of information to grow in the future.
4) You should figure out your budget for a backup storage device and removable media to use with it.
5) Consider if you plan to archive photographs or scanned files, need portability of the media or the drive itself, wish to record music for playback on some other equipment, or need ease of use.Weigh these factors along with your need to back up the files.
6) Work out the cost per MB of media for each drive you are considering.zip drives themselves are cheap however the disks are not.
Sun’s ZFS now has built-in deduplication
Posted by admin in IT Blog, SUN Solaris on November 2nd, 2009
A few years ago, Deduplication was the industries biggest buzz word. Well that hype actually pan-out and is a vital way to save disk space. In a nutshell, Deduplication is the process of eliminating duplicate copies of data.
Now instead of having an appliance dedup the data, Sun’s Zettabyte File System (ZFS) will do it for you.
The New Snow Leopard Update Blocks Intel Atom
Do you have a hacked Mac netbook? Well the new Mac OS X Leopard 10.6.2 will not work on the Intel Atom processor.
According to Stellarola, with the current developer build of 10.6.2, Apple appears to have changed around a lot of CPU related information. He suggests that if you are a Hackintosh user with an Intel Atom based netbook, stick with 10.6.1.
Keep in mind that this is the current developer build. If we are lucky, Apple will fix or adjust any CPU changes and allow Atom Hackintosh users to continue. In my Minds-Eye, this is just another way for Big Apple to rake in more money by having OS X users pay big premiums for their product.
If the final release of 10.6.2 still breaks on the Atom Processor. I am sure the hackintosh community will band together and come up with a workaround, so stay tuned.
Windows XP Freezes
There are many reasons why Windows XP freezes.
One of the reasons may be that the registry is polluted with errors, or it is likely that your computer is bogged down by temporary Internet files.
Having too many Internet files left to build up on your hard drive often cause the computer to freeze or crash.
Do Away With Windows XP Freezes For Good
The space used up by these files is truelly surprising.
Think when surfing the internet.
When asking the computer to give you certain web pages, it needs to down load an enormous number of files so as to carry out this task.
Because of this, Internet browsing is becoming more and more efficient and much quicker.
Now, if these files are left undeleted they will start to take up space and will cause problems for the machine.
another good reason that Windows XP freezes is because of a “corrupt registry”.
Your details and browsing history are what eventually form your registry database.
Your registry becomes more cluttered with each addition or subtraction of software you make.
You will start to get freezes, crashes and a huge performance dip if this accumulation is not sorted out.
All software has to log in through your registry each time you install any.
It will always leave fragmented traces if software is not uninstalled correctly.
The massing of these fragments will slow your computer as it attempts to work around the errors.
The size of your registry expands constantly.
The one draw back is that your PC will become very unstable and it’s performance will worsen if the registry grows too much.
That is the reason why it becomes slow after a while and will not perform the way they did when it was first purchased.
It is not hard to maintain your PC.
It is very important that maintenance is performed on the computer to ensure that you do not encounter any of these problems.
I’m not talking about completely re-installing Windows.
There are many programs available for download that will sort out the registry and shift fragmented temporary files.
Todays registry cleaners are;
- Intuitive to operate.
- Totally self explanatory.
They have lately been made easy to use to enable Mr & Mrs average to carry out the maintenance themselves, thus reducing the cost of putting your computer in the shop every few months.
The repair specialist will simply do the same thing with the registry, but many people still neglect to do it and end up wasteing hundreds of dollars.
The files and errors that normally cause Windows XP freezes can be corrected by using the cleaner before you shut down your PC for the night.
Try to use a cleaner on a regular basis.
You’ll not have to suffer blue screen, slow running PC, mysterious error messages, unable to load, memory strikes again or Windows XP freezes.
With only a few clicks of your mouse you can clean and repair it yourself
Editing manually can be a daunting task and risky to your computer.
get rid of Windows XP freezes for ever with a reliable registry cleaner, why take the risk?
Data Forensics
Forensics is an ever evolving science with a lot of possibilities acquire deeper knowledge about by different forensics schools or forensics colleges.
With the ever increasing importance of computers and digital media for both personal and corporate users, the number of crimes involving electronic data is now higher than ever. Thus, only data forensics experts can search computers for electronic evidence, make digital investigations, recover lost data and provide technical expertise. To count only a few of the judicial cases for which data forensics is useful, we ought to mention breach of contract, intellectual property theft, discrimination, sexual harassment and so on. Therefore, it is not that difficult to understand why data forensics is so important in the legal system.
A normal type of computer investigation cannot detect or extract bits of information remained after deletion. Data forensics will normally examine files that are hidden, deleted or even discarded, as well as fragments or file left-overs. Although it often seems impossible to recover data or to identify the criminal process, this search for the needle in the haystack is pretty successful. What relevance does such evidence have for legal cases? Well, practice has already proved it that even the course of a trial could be changed by the retrieval of deleted e-mail messages for instance.
The challenges that data forensics expert have to face are enormous. The applications do have far-reaching applications, but the work to extract digital evidence is strict and exhausting. Sometimes the necessary information is buried deep in the corporate electronic system, or sometimes, even if it is physically identifiable it is difficult to separate and analyze extensively, off line. Moreover, for a successful data collection, data forensics has to protect the extracted elements by duplication so that the information is preserved and not altered and spoiled during the process. Lots of skills, strict standards and great caution are needed for each of these steps and only real pros can succeed.
A data forensics expert should be contacted immediately, once a breach in the security system or a criminal act against electronic media is detected. This will enable the appropriate and cost-limited data collection in the best conditions possible. Moreover, it is false to assume that data forensics only applies to computer hard drives as the main systems that can store information; there are cases of criminal action involving, USB devices, CDs, DVDs and even voice mail systems. Even photocopy machines include hard drives and the scanned or copied documents can be afterwards retrieved from them.
