network issues and data backup.

Every business has vital information that is crucial for its operation.
Therefore, it is essential to make consistent and up-to-date data backups. However, you may encounter problems during the backup process, such as very slow backup speed. In this case, not only will the backups take a long time, but they will also be prone to failure. 
Network performance plays an important role.
The effective transfer rate between your device and data centers depends on the bandwidth provided by your internet service provider, as well as network speeds on nodes between your internet service provider and the data centers. Even if a speed test of your internet service provider shows that your currently available bandwidth is high, network congestion elsewhere can cause speeds to slow down. 
When internet usage increases extremely, there is a concern about overloading the system which can result in slower speeds and connection issues. Because of this it is always a good idea to keep a local backup on an external hard drive that is physically located in your home or business. This way you can always perform fast back ups and access critical information even if your network is down or there is a sudden increase in internet traffic.
In case something goes wrong with your online or offline backup system, and you lose your financial databases, accounting records, shipping data, customer data, credit card information, intellectual property or even your personal photos and files, which are precious and important to you, Kotar Data Recovery can recover your critical data.

ransomware.

Ransomware is a type of malicious software or malware, which usually takes the data on your device and encrypts it so that you can’t access it unless a ransom is paid. Anyone with important data stored on their device or network is at risk. Ransomware typically spreads through phishing emails or by unconsciously visiting an infected website.

Typically, a message is delivered that provides payment details and a timeline to pay before the data is erased completely. Some people pay to have their data restored at a huge cost but that only makes them an even greater target for future malware attacks as they have been identified as someone that will pay the ransom. And there is no guarantee that people will recover their data if they pay the ransom. Another problem is that every individual that pays to recover their data is directly funding the development of the next generation of this malware. As a result, it continues to develop, with more sophisticated variants and the costs continue to rise.

Kotar Data Recovery strongly recommends to avoid ransomware with digital security best practices. However, sometimes mistakes are made. In such circumstances, stay calm and contact a data recovery specialist for advice and recovery options. Kotar Data Recovery has been successfully recovering data from different types of ransomware. While no two ransomware cases are the same, we exhaust each and every option to recover encrypted data quickly and reliably. 

recovery from water damaged storage devices.

Did you accidentally spill a beverage over your phone? Did your device fall into the pool? Fear not, even if your device does not turn on, there is a good chance that recovery of your precious files, photos, and memories is still possible. A professional Data Recovery Lab like Kotar Data Recovery has the necessary skills and specialized equipment to safely extract information from your device. Our engineers use ultrasound to remove moisture from every nook and cranny of your device, eliminating the possibility of a short circuit that could damage your data. After doing so, they use specialized hardware and software to access the low-level storage on your device and extract your valuable data. As one of Silicon Valley's only professional labs, we are confident in our expertise and success rates so we offer a no-data-no-charge policy to ensure that you are only paying for results. Our pricing is determined after an in-depth complimentary evaluation of your damaged media and is based solely on the complexity of the problem and the man-hours required to solve it.

phone data recovery.

Kotar Data Recovery specializes in recovering data for Apple products, including iPhones. We can perform deep level data recovery from devices that are broken or have suffered water or fire damage. Our lab is located in San Jose in the heart of Silicon Valley. When deciding who to trust to recover your data remember that the first data recovery attempt is by far the most crucial one. If the person recovering your data is not properly qualified they can further damage your device and render the data unrecoverable. Phone repair shops are not equipped with professional data recovery equipment and lack the knowledge and expertise to do anything beyond basic software data recovery. If your phone is damaged and contains data which is important to you, it is crucial to find a professional data recovery service right away.

the anatomy of a hard drive.

The platters are the part of the hard drive that contains all of the data on a thin layer of metal alloy coating. The surfaces of the platters are completely flat. The magnetic field of tiny portions of this coating determines which parts of the disks are “0”s and which are “1”s. Hard drive platters have billions of these regions per each surface of the platter, and hard drives have several platters inside them. The tiny read/write heads inside a hard drive, hover just a few nanometers above the platters and pick up or alter the magnetic signals given off from the platters. In order for the heads to do their job properly, the platters have to be perfectly smooth. A slightly raised area on a platter’s surface, for example - a little bit of dust - can be devastating. If the heads make contact with the platters at any time, they can scratch a part of the thin layer of metal coating that holds the data. To recover data from a hard drive with scratched platters, the platters must be carefully extracted from the hard drive’s chassis in a data recovery clean air lab and any embedded particles must be removed. In most cases, the read/write heads, which are usually responsible for scratching the platters, must be replaced. Sometimes the damage is so bad that the entire chassis must be replaced.

deep learning in data recovery.

Recent advances in Deep Learning have dramatically improved our ability to recover corrupted images. Novel architectures such as GANs allow for the reconstruction of partial files with the power of Artificial Intelligence. At Kotar data recovery we constantly keep up with cutting edge research to incorporate it into our recovery process as soon as possible. We foresee artificial intelligence being the driver of a lot of innovation in the data recovery field, and so we keep an especially close watch on developments in this area. By exploiting the predictable nature of file structure Deep Learning techniques are unlocking brand new recovery capabilities and enabling us to restore data on cases that were completely unsolvable until very recently.

data security.

The amount of data that is stored electronically has been exploding. Today more than ever, all data should be stored securely. Ideally, we should encrypt all data stored on our system. Encryption takes the data and makes it inaccessible to anyone without the unique decryption key.

However, this can not completely protect us from data breaches due to human error. A good example of data breaches due to human error are old drives that haven’t been properly erased. A recent data security study showed that over 60% of the second-hand hard drives randomly purchased online contained personal data such as name, address, date of birth, photos and financial information of the original owner. Furthermore, over 10% of hard drives that previously belonged to businesses contained financial data, emails and customers' data.

This clearly implies that dragging files to the Recycle Bin does not erase data. To sanitize a disk for reuse, resale, or disposal by securely erasing the data, a disk wiping process should be performed. Disk wiping is a non-destructive way of permanently removing data and preventing the recovery of that data. If the data is highly sensitive then the best option is to physically destroy the drive.
