The process of files getting damaged 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 because the larger a hard disk is and the more data is placed on it, the more likely it is for data to become corrupted. There're a couple of fail-safes, but often the information is damaged silently, so neither the file system, nor the admins notice a thing. As a result, a damaged file will be handled as a good one and if the hard disk is part of a RAID, that particular file will be copied on all other drives. Theoretically, this is done for redundancy, but in practice the damage will get even worse. The moment a file gets corrupted, it will be partially or entirely unreadable, so a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most widely used server file systems feature various checks, they often fail to identify some problem early enough or require a long period of time to check all files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

We have tackled the issue of silent data corruption on all our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one out there which checks all the files instantly by employing a checksum - a digital identifier which is unique for each file. When you upload content to your account, it will be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as corrupted, it is replaced instantly with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the remaining SSDs. ZFS needs plenty of physical memory in order to perform the real-time checks and the benefit of our cloud web hosting platform is that we employ multiple powerful servers working together. If you host your Internet sites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not have to deal with any silent data corruption issues in case you buy one of our semi-dedicated hosting solutions because the ZFS file system that we work with on our cloud hosting platform uses checksums to ensure that all of your files are undamaged all the time. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. As we store all content on multiple drives at the same time, the same file uses 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 chance of the bad copy to be synchronized on the rest of the hard disks. ZFS is the sole file system out there which uses checksums, which makes it much more dependable than other file systems that are not able to identify silent data corruption and copy bad files across drives.
