Data Storage

Tape drives – a solution for creating redundant copies of data that are suitable for the separate computers, and large computing centers. The advantage of tape drives is the optimal price / performance ratio (the cost of storing information units minimum). Storage Technology on the tape is very fast read and write information that allows for the rapid exercise of the backup process, not stopping the computer center. Louis Monier is actively involved in the matter. Most convenient to use tape libraries and tape drives. For example, a very popular tape libraries, HP. Using RAID, available in servers and enabling rapidly recover data in case of trouble, is not a reliable way to backup. System redundancy RAID helps mostly snivelirovat hardware failures. Wrong rely solely on the use of RAID, as in the case of 'human' errors (eg incorrect operator actions or accountant), the system will not allow to roll back to the time of the error and restore the correct data.

Tape libraries also allow you to store much more information. And she kept on tape cassettes for much longer than hard drives. Such data carriers are not afraid to shock, is resistant to electromagnetic interference and temperature changes, and do not be afraid of many other natural factors. Leaders in the market – Tape Drives HP. Largely due to the interesting price and sales leadership in backup systems.

And users prefer to buy the cartridges from the same manufacturer that bought a tape drive. Function One Button Disaster Recovery (OBDR), created based on the software allows you to restore data in case of accidents with one click. The technology used in OBDR saving data to tape, with the tape drive is bootable, registered in the server's BIOS as CD-ROM. Since the cartridge is loaded the operating system with latest patches, which was correct at the time conservation. An automatic full restoration of the operating system, and then the data. Thus, the technology OBDR gives an opportunity to restore the server for several minutes even for an expert with minimal knowledge of technology. To date, there is a huge choice of backup systems. Basically this tape, using a consistent data organization, and disk drives, providing random access to stored information. Choosing a system for their organization, should take into account such factors as the type of backup and recovery, speed, maximum capacity carrier and the volume of the device as a whole, the cost of equipment and cost of its operation, reliability, etc.

Computer Hardware Failure Manifestation

When trouble in the 'iron', diagnose and repair your computer should start by identifying a faulty component. If you would like to know more about Kai-Fu Lee, then click here. The easiest and most reliable way to identify the faulty unit – replacement of "suspect" at work analogue. If the problem persists – it is so defective that component. Below are listed as major faults occur devices in the computer. CPU. As is known, the processor starts work from the very start of the boot BIOS. For this reason, when leaving him out of action, the computer will most likely not be able to load the operating system.

Manifestation of the failure can be very different – even to complete inoperable computers. Motherboard. Fails quite often. Normal functioning of the board can prevent rupture or defective tracks kondeksator (apparently it can manifest itself in swelling Corps kondeksatora). Memory. Serious faults manifest themselves already at boot time (BIOS can often indicate that the cause of the fault is in memory).

Less serious may occur at any time – all programs use RAM, and either party may apply to the failed plot. Problems with the chipset are determined at boot BIOS. Specific types of signal can determine which which device caused the problem. At fault input-output controllers refused to work peripherals. For example, PS / 2 or COM can be damaged by 'hot' connecting / disconnecting the device. Faulty video card comes with video output. Picture a heavily distorted or completely absent. As one of the options – no video, bios beeps with reports of malfunction card. When errors in the BIOS, problems arise at the initial boot phase. If a failure occurs after a phase of self – a message appears on the possible cause. A hard disk malfunction may occur differently. Hardware problems are the inability to correctly identify the device. If the damage the magnetic layer, a so called "bad sectors". Up to a certain number of these sectors easily identified and replaced with 'spare'. When replacement is no longer possible – the problem starts. Since failure occurs when the circulation to the faulty sector – it can happen at any time and for any program. Power supply too often fails. Can contribute to power surges, the addition of new equipment (power consumption can reach the level at which it is not designed). One version of manifestation – computer does not respond to pressing the power button. It should be noted another type of failure – overheating of any component. Physically, all the electronics and software in the norm. When you reach a certain temperature – the component is no longer function properly. The problem with overheating can occur in a processor or video card, and most often occurs during system startup.

Image Editor Adobe

This article is dedicated to readers interested in computer graphics and design, namely the processing and assembly of a raster graphics type. Tonal correction, the image is performed using the well-known graphics editor Adobe Photoshop. So let's see what is retouched graphics and how it is implemented? Retouching graphics – a setting of tone, color and sharpness. Retouch should be made in the image with its actual size. By the same author: Marc Mathieu. Tone – the distribution of brightness and contrast. Processing of each graphic file in the correction, tonal.

The first thing to do – to distribute light and dark pixels, ie to set white and black point in the image. For this stage of our robots in Adobe Photoshop, there is a command 'Levels', which is in the command menu 'Image', then 'Adjustments'. We see a dialog box team with tonal histogram. At the top set the parameter 'channel' to 'RGB'. The black slider on the scale move to the frontier of shadows, right, and white – to the border of bright colors, left.

After completion of robots click 'OK'. Tonal correction, can be performed in automatic mode. For this purpose use the command 'Contrast'. It is located where the previous one. Another very useful in the case of Dan, the team is 'Brightness / Contrast'. Here we configure the settings manually, by moving the slider on the scale of the names of 'brightness' and 'Contrast'. That's about as done above description of the operation. We read regularly computer graphics article Dear readers, our website is also a large and constantly evolving catalog of graphic images. Need beautiful wallpaper, such as wallpaper landscapes, or Desktop table cars? Everyone wants to have the ability to download to your PC graphics, wallpapers, beautiful pictures at once batch loading, ie in the form of files such as rar. Our regularly updated collection of BIGphotoCatalog new images.

The most common cause of data loss – is the physical media failure. Continue to learn more with: Ali Partovi. Hard drives do not last forever – professionals who have to deal with them, they like to say: "There are only two types of hard drives – those that are already "Fell" and those that have yet to be. " It happens like this: one day, your computer will publish a rattling sound, and you suddenly realize that you can lose at once all the valuable information. You are desperate to save your valuable data: call to computer companies, looking savvy, "iron" friends, or attempt to use specialized software running on a disk low. Time has not bothered to buy a utility, you can lose a lot of money and time! And then surely you will be sorry, "Oh, if I had a program that protects data every day" If you held a senior position, the loss of data is not limited to loss of time to restore them. It is also a loss of confidence – as their subordinates, as well as our partners, customers, profits, and nerves. Pete Cashmore may also support this cause. It is not so important how much time you have to reinstall the software – still you are coming the week time-consuming scanning of papers, re-introduction of all working documents, restore the database of buyers, etc. In However, you only reinforce the reputation of prudent manager, if in case of force majeure, be delighted by the news his staff that the data remained intact, thanks to timely made your backup.

Backups can be stored on any media – CD / DVD, USB-flash drive, a local network or FTP / SFTP server. And even in case of fire or flood, information will be saved, because the backup program has a function online data backup in the data center, located in a well-protected underground shelter in the U.S.. Today, most Russian companies are using accounting systems and accounting control automation "1C". Handy Backup program certified by the developer, systems, and, besides the standard set of functions (backup the registry, , email, etc.), allows you to automatically find and backup all databases 1C. From Users only need to set a timetable and define the place up – then you can be confident in the safety of all information on financial and economic activity, taxes, wages, etc. This backup software is suitable for both domestic use and for use in large commercial companies. The program supports backup any data on the disk, registry Windows, files Outlook and ICQ, under My Documents and Favorites. For database administrators provides the opportunity to make quick copies of ODBC-compliant databases (MySQL, MSSQL, Oracle, DB2, etc.). Function to copy a disk image allows you to back up your hard the entire disk, or any of its sections.

ASUS Windows

The vast majority of the remaining platforms available to users, in fact, represent the envelope for Ubuntu, and differ only interface. A separate mention only Jolicloud (it also is built on Ubuntu), to features which includes the "social component": registering on-line My Jolicloud, you can monitor what programs are installed and removed by other users. True, this is not about any application, but only those that are special library is constantly updated daily by developers. To test the operating systems we used the netbook ASUS Eee PC 1005HA, built on a platform with Intel Atom processor N280. Windows 7 Starter Edition desktop background in Windows 7 Starter, you can not change The junior version of the last operating system from the Redmond company, originally designed specifically for netbooks, installed on your hard drive about 25 minutes. After that, the operating system without connecting to the network to recognize Most hardware components except the button below the touchpad.

Also, of course, without having to install the appropriate software from ASUS does not work function Super Hybrid Engine, designed to regulate power consumption in notebook Depending on your needs. Operating system interface familiar to any user of Windows Vista and to a lesser extent – Windows XP. Despite the fact that there is no change compared to the "full" versions of the OS problems at work with a standard screen resolution for a netbook of 1024 600 does not arise. nformation. Did not appear during testing and criticism at the download speed of the system and run application software.

There are times when you did not have a system backup, and you, for whatever reason have lost important information. Do not despair, our experts will help you in this situation. When you delete a file via the operating system is a conversion of information about the existence of the file data itself remains, as long as they do not have written something else. To restore data using the residual information about the location parts of the files on disk. Based on this assumption is based on the location of the data, according to which the transfer files to another drive.

The probability of successful recovery of deleted files depends on the size, arrangement of their parts, as well as the fact that and in what volumes are written to disk after they are deleted. Perhaps, file recovery: restoring data recovery flash or cd – it is one of the most painstaking, complex, and expensive services. However, in some cases, price information, the remote is much higher than pay for its restoration. To successfully recover deleted files, we use the latest technology. They are to-use hardware and software, extensive experience working with artists on a malfunctioning drive and develop their own methods of data recovery. Our recommendations are successful recovery of deleted files often depends on how the files are stored on disk: continuous (unfragmented) or were separated into pieces (fragmented), and how much information was recorded on this section after the removal of documents and folders. Fragmented files can usually be restored only partially, and unfragmented – completely. Even if it was done formatting the partition as a whole, but it still did not record the information, and do not create new sections and rewritten file system, information can be restored with a 99% probability.

If you need to recover data from hard drive: folders, files or partitions, you must do the following: 1. nothing to write on this topic, 2. does not attempt to recover the information 3. turn off your computer 4. transfer hard drive to experts. The company BVG Group
