The process of files getting damaged as a consequence of some hardware or software failure is called data corruption and this is one of the main problems that hosting companies face since the larger a hard disk drive is and the more data is placed on it, the much more likely it is for data to get corrupted. You can find different fail-safes, but often the data becomes damaged silently, so neither the file system, nor the admins detect a thing. Thus, a damaged file will be treated as a good one and if the hard disk drive is a part of a RAID, the file will be duplicated on all other disk drives. In theory, this is done for redundancy, but in reality the damage will be even worse. When a file gets corrupted, it will be partially or fully unreadable, therefore a text file will not be readable, an image file will display a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most well-known server file systems have various checks, they often fail to identify some problem early enough or require an extensive period of time in order to check all files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Web Hosting

We have tackled the matter of silent data corruption on all our web hosting servers by using the advanced Z file system, or ZFS. The latter is better than other file systems as it is the only one in existence which checks all the files immediately by employing a checksum - a digital identifier that is unique for each 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 analyzes the checksum of all files and when any file is detected as corrupted, it is replaced immediately 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 lots of physical memory to execute the real-time checks and the benefit of our cloud website hosting platform is that we use multiple powerful servers working together. If you host your sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption since all our storage servers work with the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it will be placed on a couple of redundant drives being employed in a RAID i.e. the files shall be the same across all disks. All of the copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, so if it identifies a mismatch, that would indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other drives. Even if there's a sudden blackout, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, extending the time needed for the server to get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
