Data corruption is the unintended transformation of a file or the loss of information which often occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file may become partially or entirely corrupted, so it'll no longer function correctly since its bits shall be scrambled or lost. An image file, for instance, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. If this kind of a problem appears and it is not recognized by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that is part of a RAID array where the info is synced between various different drives, the corrupted file will be reproduced on all the other drives and the harm will be long term. A number of commonly used file systems either do not have real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Cloud Website Hosting

We have dealt with the issue of silent data corruption on all our cloud website hosting servers by using the advanced Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one in existence which checks all the files right away by employing a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and continually 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's replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the rest of the NVMes. ZFS requires lots of physical memory to carry out the real-time checks and the advantage of our cloud hosting platform is that we take advantage of multiple powerful servers working together. If you host your sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you purchase one of our semi-dedicated hosting packages, you will not have to worry about silent data corruption because we use ZFS - a high level file system that monitors all the files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between a number of NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no danger for any part of your content at any moment. In comparison, all of the other file systems execute checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the remaining drives as well and you could lose important information. As this is not the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
