The process of files getting damaged caused by some hardware or software failure is called data corruption and this is one of the main problems that web hosting companies face because the larger a hard disk drive is and the more information is placed on it, the much more likely it is for data to be corrupted. There're various fail-safes, still often the information gets corrupted silently, so neither the file system, nor the admins detect anything. Consequently, a damaged file will be treated as a standard one and if the hard disk is a part of a RAID, the file will be copied on all other drives. In theory, this is for redundancy, but in practice the damage will get even worse. Once a given file gets corrupted, it will be partially or entirely unreadable, so a text file will not be readable, an image file will show a random mix of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most widespread server file systems include various checks, they often fail to identify a problem early enough or require an extensive period of time in order to check all files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Website Hosting

We have dealt with the issue of silent data corruption on all our shared website hosting servers by using the advanced Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one in existence that checks all files in real time by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and continually synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and if any file is detected as damaged, it's replaced promptly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the other SSDs. ZFS requires a lot of physical memory in order to carry out the real-time checks and the benefit of our cloud hosting platform is that we employ multiple very powerful servers working together. If 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 experience any kind of silent data corruption issues whatsoever should you acquire one of our semi-dedicated hosting plans as the ZFS file system that we employ on our cloud hosting platform uses checksums to guarantee that all files are intact all of the time. A checksum is a unique digital fingerprint that is assigned 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 drives and what ZFS does is that it compares the checksums between the different drives in real time. If 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 bad copy to be synchronized on the other drives. ZFS is the sole file system you can get that uses checksums, which makes it far superior to other file systems that cannot detect silent data corruption and copy bad files across drives.
