Data corruption is the accidental change of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software malfunction, and because of this, a file may become partially or completely corrupted, so it'll no longer function properly as its bits shall be scrambled or missing. An image file, for example, will no longer display an actual image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When such an issue occurs and it's not recognized by the system or by an admin, the data will become corrupted silently and in case this happens on a drive that's part of a RAID array where the information is synchronized between different drives, the corrupted file will be copied on all of the other drives and the damage will be long term. Numerous widespread file systems either don't have real-time checks or don't have good ones that will detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

We've tackled the problem of silent data corruption on all of our shared web hosting servers by using the advanced Z file system, or ZFS. The latter is superior to other file systems as it is the only one on the market that checks all 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 continually synced between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as damaged, it's replaced promptly with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be copied on the remaining NVMes. ZFS needs lots of physical memory to execute the real-time checks and the benefit of our cloud hosting platform is that we employ multiple powerful servers working together. If you host your websites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you go for one of our semi-dedicated hosting solutions, you will not need to worry about silent data corruption since we use ZFS - a high level file system that monitors all files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no threat for any part of your content at any time. By comparison, all of the other file systems carry out checks only after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the remaining drives as well and you could lose important information. Since this isn't the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
