As computers and digital products become more widespread in people's work and lives, more and more data are stored on hard drives. Ninety per cent of internet users are known to have experienced the loss of hard disks, mobile phones, diskettes, e-mails and, if important customer data or financial data were lost, the consequences would be difficult to envisage. The cost of restoring the data is enormous, if not thousands of dollars. After hard disks, compact discs, e-mails, cd-roms, which are traditionally used for data preservation, network hard drives based on cloud storage have become popular in the country and are an important means of back-up data for many units, but are not available for personal users because of fees。
Cases
It's a waste of money
After school hours to help produce wedding videos and photographs, small photographers who study photography often make extra extra money. Not long ago, he accidentally formatted the camera cf card, which led to the loss of a large amount of video material. As a last resort, i had to go to a nearby digital store to repair it, “when i had a 24g file in kari, it took more than 1,800 to repair it, but only to format it better”. According to jianxing, it is a big deal to spend less on repairs. " it was agreed that the video would be produced the next day, and the result was two days to go because of the data loss.” as a result of the accident, clients had doubts about their service and level, which had a significant impact on the credibility of the studio。
The sudden damage to the hard drive and the sudden loss of big data will almost leave the data for a certain number of years blank: “my computer spent four years, and it didn't feel like there was a problem, but suddenly one day it didn't start, so it was repaired that it was broken and the data could not be copied.” in a novel that works in a media company, although all the work materials in the computer are backed up, a large amount of personal data is in the private computer and has to be used for data recovery, “it is fortunate that the hard drive is not so badly damaged that most of the data have been recovered, but it feels too bad.”
Investigations
90% of internet users have lost data
In recent days, journalists have interviewed li jianbo, associate professor at the institute of information of qingdao university, “the reasons for the loss of computer data are many, but most of them are still caused by hard drive damage or artificial formatting and deletion”. Li jianbo states that excessive temperatures and severe vibrations during collisions can cause damage to the hard drive, even if it is not correctly turned on and turned off, making the hard drive increasingly vulnerable. “however, now that hard drives are more and more stable, fewer people are losing data because of the damage to the hard drive, but there are not many missing disks and e-mail messages.” according to statistics, more than 90 per cent of computer users in the country have experienced data loss, while less than 10 per cent have succeeded in restoring the data。
In addition to computers, mobile phones, mobile hard drives and cd-roms are also the carriers that store a large amount of data. Journalists'surveys have found that more and more people are used to keeping data or photographs on their mobile phones for easy access, but that data have been lost to a greater or lesser extent as accidents continue to occur, such as the dropping of mobile phones, frequent changes in mobile phones and the formatting of memory cards. "i had a lot of precious photos on my phone, and i lost everything and all my friends' contacts, and i couldn't recover." a few weeks ago, a small week of missing mobile phones complained to journalists。
Various types of data are known to be lost, such as corporate contracts, financial data, textual information such as experimental data and valuable visual information. “our company's core `rich' is in a computer, with plans and programs that are likely to collapse once lost. Although some of these data are backed up, a large number of new data are generated every day, and if they are lost, they will be recovered regardless of the cost.” the king's manager of a decorating company told the press。
There's a million dollars to fix the data
In recent days, journalists have interviewed several computer after-sales centres in aoshima. Mr. Yuan, a staff member of the after-sales service, said: “the recovery of data is generally expensive, we start here at $800, and based on the spatial pricing of the data, such as 10g, it takes 2,000 years.” according to mr. Yuan, the large number of people repairing the data due to the damage to the hard drive, or even the fact that some have spent tens of thousands of dollars to repair the data, does not guarantee that all the information will be repaired because of the different extent of the damage to the hard drive, “if the information is not of particular importance, we do not recommend that it be done and that it would be more advantageous to change the hard drive directly”. According to a staff member of china-technology, the cost of data recovery is high and some require an identical hard drive to export the data, “if repaired, we will charge a fee based on the degree of damage”. The staff of the sunshine rains information technology service (beijing) ltd. At the qingdao service centre, substation qingdao, are more direct, saying that the company requires $900 to restore the data without opening and $1,900 to open。
In order to obtain further information on the fees charged for data restoration, 11 p. M. Journalists came to qingdao electronic information city and the encyclopaedia for field visits, asking 78 businesses engaged in data recovery operations to learn that most businesses were not able to guarantee that all data would be repaired, that even if the user hard drive data were ultimately not restored, the costs originally collected would not be refunded, and that the price would be determined on the basis of the degree of damage to the hard drive and the importance of the data. “if the data were omitted by mistake, about $200 could be repaired, but if the hard drive was damaged, it would cost at least $800.” the technicians of qingdao centrifugal science and technology limited stated that “the specific cost also depends on the space occupied by the data and the extent of the damage to the hard drive”. And the manager of qingdao crown technologies ltd. Told the reporters that the company's data were better repaired than the personal data because the company's data were generally more important: “i picked up a list of a power company, and a broken hard drive contained a list of all their clients, and the obvious knew that money was not a problem if the data could be restored. We made $8,000 on this list."
Interviews by journalists found that the average hard disk data recovery was less than a thousand dollars, high or even tens of thousands, and that some maintenance centres were vague about the rates. Despite this, however, a large number of hard drive-damaged people have made data repairs, even at a cost of tens of thousands. Data released by the national computer emergency response centre in 2011 showed that, based on the 1 per cent annual loss of more than 40 million desktops in the country and the thousands of yuan per repair cost, the market size of the data was restored to 400 million yuan per year。
Problem
The data is stored on the web, but it's cold
“technology of cloud storage is now well developed and widespread in network operations, but it is not yet the preferred of individual users. According to the expert, the internet industry in the country is large, and the mainstream web is beginning to try to provide a fee-paying service, such as a well-known cloud web dish in the country, with 5g free space for registration, up to 15g free of charge through the completion of a mission, and 20g space for members to open up, but at a cost of $10 per month, the 100-degree dish also provides a menu for internet users with a maximum capacity of 100g, or $500 per year. The internet network, which is primarily intended for enterprises, does not provide free space. The basic package consists of 10 g and 5 sub-accounts, at $3,600 per year, plus $720 per additional 5 g space per year and $120 per additional sub-account per year。
However, most internet users do not buy such fee-paying services. "i've already paid for the internet. How can i charge extra for cloud storage? I'd rather just buy a mobile hard drive." a student at the china ocean university told journalists that the original use of the disk was free of charge and that the value-added services were almost non-existent on their own, and that the fees were unfair to themselves. A journalist survey found that internet fees were not acceptable to most, especially to individual users who stored personal data only. By contrast, the internet is popular in enterprises. “there is no free lunch in the world, the services paid for are solid, the company has a lot of information to store, it is safe and convenient to put it on the internet, and the money spent on storage is worth the company's interests.”
Interviews with journalists found that the choice of free internet disks was generally made by individual users, most of whom often simply registered an account for uploading or downloading resources or placed their resources as backup. For enterprises, free disks are more or less unsatisfied, such as the unstable speed of uploading or downloading, limited capacity, the inability to transmit large files once-in-time, the limited format of transmissions, the limited time of storage, etc. The fee-paying disk can provide high-quality services to enterprises and, for enterprises, “gains more than costs”。
In response, li jianbo also expressed his views. He said that the domestic grid went through a process ranging from free to fee-free, and many people felt that there was a fee gap that might not be accepted so quickly. It is understood that many internet boards are now providing permanent free space services to cater to the general public, such as the kinsan express, which provides 100 g permanent free capacity for internet users。
Watch out for backup
A number of causes of computer hard drives are known to cause damage, such as incorrect turn-off, switch-off, unstable voltage, strong vibrations on hard drives while reading and writing data, and frequent compression of hard drives. Important data and information in computers, whether critical to business or to individuals, are lost at once, and the hard-earned accumulation of effort is lost, while the heavy weight affects the proper functioning of enterprises. So, in order to prevent the loss of data caused by hard drive damage, we need to develop good data backup habits。
In general, the probability of simultaneous failure of two or more computers is relatively small, so that data can be stored on multiple computers as backup. In addition to this, the information in the computer can be transferred directly to the mobile hard drive, which can be backed up in the event of a computer failure, or stored on a pallet. Moreover, the current fashion is to synchronize the backup on the internet and store the files on the disk. There are currently many web sites dedicated to managing documents, which allow for the network storage of local documents and the simultaneous updating of data on different computers. The software allows for the timely uploading of information to the network, free of computer space and easy access to online information if computer data are lost。
While backup is available in many ways, mobile hard drives and palettes can also be lost, either way does not guarantee 100 per cent coverage, so multiple channels are the safest. (journalist, chen ko, intern, lee mon ho)
