The process of files being corrupted as a consequence of some hardware or software failure is called data corruption and this is among the main problems that hosting companies face since the larger a hard disk drive is and the more information is kept on it, the much more likely it is for data to become corrupted. You'll find a couple of fail-safes, still often the data is corrupted silently, so neither the particular file system, nor the admins see anything. Thus, a bad file will be handled as a good one and if the hard disk is a part of a RAID, that particular file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will be even worse. When a given file gets damaged, it will be partially or completely unreadable, which means that a text file will no longer be readable, an image file will present a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most well-known server file systems feature various checks, they often fail to detect a problem early enough or require a vast time period in order to check all files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Website Hosting

We've resolved the problem of silent data corruption on our website hosting servers by using the modern Z file system, or ZFS. The latter is superior to other file systems as it is the only one on the market which checks all files immediately by using a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and regularly synchronized between them for redundancy. ZFS constantly compares the checksum of all files and if any file is detected as damaged, it is replaced promptly with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the rest of the SSDs. ZFS requires lots of physical memory in order to execute the real-time checks and the advantage of our cloud web hosting platform is that we employ multiple powerful servers working together. In case you host your websites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not encounter any silent data corruption issues whatsoever if you get one of our semi-dedicated hosting packages due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all of your files are intact all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Since we store all content on a number of drives simultaneously, the same file has the same checksum on all 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 has to be, it replaces that file with a healthy copy without delay, avoiding any possibility of the bad copy to be synchronized on the other hard drives. ZFS is the only file system you can get which uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and copy bad files across hard drives.
