The process of files getting damaged owing to some hardware or software failure is called data corruption and this is among the main problems which web hosting companies face because the larger a hard disk drive is and the more data is placed on it, the more likely it is for data to get corrupted. There are various fail-safes, but often the info is damaged silently, so neither the file system, nor the admins detect a thing. Thus, a corrupted file will be treated as a standard one and if the hard disk drive is a part of a RAID, that particular file will be duplicated on all other drives. In theory, this is done for redundancy, but in practice the damage will be worse. Once some file gets corrupted, it will be partially or fully unreadable, so a text file will not be readable, an image file will display a random combination of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your website content. Although the most commonly used server file systems feature various checks, they often fail to identify some problem early enough or require a long time period in order to check all of the files and the hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
The integrity of the data which you upload to your new cloud website hosting account shall be ensured by the ZFS file system which we make use of on our cloud platform. Most of the internet hosting service providers, including our company, use multiple HDDs to store content and considering that the drives work in a RAID, identical information is synchronized between the drives at all times. If a file on a drive gets corrupted for some reason, however, it is more than likely that it will be duplicated on the other drives because other file systems don't include special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the damaged copy shall be replaced with a good one from another hard disk. Due to the fact that this happens in real time, there's no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't encounter any silent data corruption issues whatsoever in case you obtain one of our semi-dedicated server packages due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all of the files are intact at all times. A checksum is a unique digital fingerprint that is allotted to each and every file stored on a server. Since we store all content on multiple drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any probability of the corrupted copy to be synchronized on the rest of the drives. ZFS is the only file system you can find that uses checksums, which makes it much more dependable than other file systems that are unable to detect silent data corruption and copy bad files across hard drives.
