The process of files getting corrupted as a consequence of some hardware or software failure is referred to as data corruption and this is one of the main problems which hosting companies face since the larger a hard disk is and the more data is kept on it, the much more likely it is for data to be corrupted. You can find various fail-safes, yet often the info gets damaged silently, so neither the file system, nor the admins detect anything. Consequently, a bad file will be treated 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 for redundancy, but in reality the damage will get worse. The moment some file gets corrupted, it will be partly or entirely 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 shall be impossible to unpack, so you risk sacrificing your website content. Although the most popular server file systems include various checks, they frequently fail to detect a problem early enough or require a long time period to check all files and the web hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Website Hosting
We have resolved the matter of silent data corruption on our shared website hosting
servers by using the amazing Z file system, or ZFS. The latter is superior to other file systems as it is the only one out there which checks all of the files immediately by employing a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it will 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 quickly with a good copy from some other disk. As this happens in real time, there is no risk that a corrupted file may remain or may be duplicated on the rest of the SSDs. ZFS requires a lot of physical memory to execute the real-time checks and the advantage of our cloud hosting platform is that we use multiple powerful servers working together. If you host your Internet sites with us, your info 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 employ the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of each and every file. When you upload content to your account, it will be kept on a couple of redundant drives employed in a RAID i.e. the files shall be the same across all drives. All of the copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the copies in real time, so if it finds a mismatch, which would indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other drives. Even if there is a sudden power failure, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, prolonging the time needed for the server to return online. ZFS is the only file system that can truly protect your content from silent data corruption.
