The process of files getting damaged owing to some hardware or software failure is known as data corruption and this is one of the main problems which Internet hosting companies face since the larger a hard drive is and the more info is kept on it, the more likely it is for data to become corrupted. You'll find several fail-safes, still often the data becomes damaged silently, so neither the particular file system, nor the admins notice anything. Consequently, a damaged file will be handled as a good one and if the hard disk drive is a part of a RAID, that file will be copied on all other drives. In theory, this is for redundancy, but in reality the damage will get worse. The moment some file gets corrupted, it will be partially or completely unreadable, therefore a text file will no longer be readable, an image file will display a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most widely used server file systems include various checks, they quite often fail to identify some problem early enough or require a long time period in order to check all the files and the web hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Hosting

We've resolved the problem of silent data corruption on all of our shared hosting servers by using the hi-tech Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one out there which checks all of the files immediately by employing a checksum - a digital identifier which is unique for each file. When you upload content to your account, it'll be stored on several NVMe drives and continually synchronized between them for redundancy. ZFS constantly examines the checksum of all files and in the event that any file is detected as damaged, it's replaced immediately 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 remaining NVMes. ZFS requires plenty of physical memory to perform the real-time checks and the advantage of our cloud hosting platform is that we take advantage of multiple powerful servers working together. In case you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption as all our storage servers use the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it'll be kept on several redundant drives working in a RAID i.e. the files will be the same on all drives. All of the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, so if it identifies a mismatch, that will indicate that one of the copies is corrupted, it'll swap that file with a healthy copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, prolonging the time needed for the server to go back online. ZFS is the file system that can truly protect your content from silent data corruption.
