The process of files getting damaged because of some hardware or software failure is called data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard drive is and the more info is stored on it, the more likely it is for data to become corrupted. There are several fail-safes, but often the data becomes damaged silently, so neither the file system, nor the administrators see anything. Thus, a bad file will be handled as a good one and if the hard disk drive is part of a RAID, that file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will be even worse. Once a given file gets corrupted, it will be partially or entirely unreadable, which means that a text file will not be readable, an image file will display a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most frequently used server file systems include various checks, they quite often fail to detect some problem early enough or require an extensive time period to be able to check all the files and the web hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the data uploaded in every single cloud website hosting
account which is created on our cloud platform since we employ the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for every single file. We will store your information on a large number of SSD drives that work in a RAID, so the very same files will be available on several places at the same time. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with a healthy version from some other drive inside the RAID. No other file system uses checksums, so it is possible for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not need to deal with any silent data corruption issues in case you purchase one of our semi-dedicated hosting
plans due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums in order to guarantee that all of your files are intact all the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. Because we store all content on multiple drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any possibility of the bad copy to be synchronized on the rest of the hard drives. ZFS is the only file system you can get which uses checksums, which makes it much more dependable than other file systems which are unable to identify silent data corruption and copy bad files across hard drives.
