The process of files getting corrupted resulting from some hardware or software failure is called data corruption and this is among the main problems that hosting companies face as the larger a hard disk drive is and the more information is kept on it, the more likely it is for data to be corrupted. You will find a couple of fail-safes, still often the data gets corrupted silently, so neither the particular file system, nor the administrators see anything. Thus, a damaged file will be handled as a standard one and if the hard disk drive is part of a RAID, the file will be copied on all other disk drives. In theory, this is for redundancy, but in practice the damage will be worse. The moment a file gets corrupted, it will be partly or entirely unreadable, so a text file will no longer be readable, an image file will display a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most frequently used server file systems feature various checks, they quite often fail to identify a problem early enough or require an extensive period of time to check all the files and the server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

We have dealt with the matter of silent data corruption on our cloud hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems because it is the only one out there which checks all the files right away by employing a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it will be stored on several NVMe drives and constantly synced between them for redundancy. ZFS regularly analyzes the checksum of all files and in case any file is detected as corrupted, it's replaced promptly with a good copy from another 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 needs lots of physical memory to execute the real-time checks and the benefit 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 info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not have to deal with any kind of silent data corruption issues in case you purchase one of our semi-dedicated hosting solutions since the ZFS file system that we employ on our cloud hosting platform uses checksums to guarantee that all files are intact all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. As we store all content on multiple drives at the same time, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. When 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 other hard disks. ZFS is the sole file system out there which uses checksums, which makes it much more reliable than other file systems that are unable to identify silent data corruption and copy bad files across hard drives.
