The process of files being damaged resulting from some hardware or software failure is referred to as data corruption and this is one of the main problems that hosting companies face since the larger a hard disk is and the more info is stored on it, the more likely it is for data to become corrupted. There are different fail-safes, but often the information gets corrupted silently, so neither the file system, nor the admins detect a thing. As a result, a bad file will be handled 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 disk drives. Theoretically, this is for redundancy, but in practice the damage will get worse. When a file gets damaged, it will be partly or completely unreadable, which means that a text file will no longer be readable, an image file will show a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most widespread server file systems feature various checks, they frequently fail to find some problem early enough or require a vast time period to be able to check all files and the web hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Web Hosting

We have resolved the issue of silent data corruption on all of our shared web hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems as it is the only one on the market that checks all files instantly by employing a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and frequently synced between them for redundancy. ZFS regularly examines the checksum of all files and in the event that any file is detected as damaged, it is replaced quickly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the rest of the SSDs. ZFS needs plenty 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 very powerful servers working together. In case you host your Internet sites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption because all our storage servers make use of the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it'll be kept on several redundant drives being employed in a RAID i.e. the files shall be the same across all drives. All copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, and if it discovers a mismatch, which would indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other disks. Even if there's an unforeseen blackout, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some malfunction, extending the time needed for the server to get back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
