Data corruption is the unintentional change of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software failure, and because of this, a file could become partially or completely corrupted, so it will no longer function properly because its bits will be scrambled or lost. An image file, for instance, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In case this kind of a problem occurs and it is not found by the system or by an administrator, the data will become corrupted silently and when this happens on a drive that is a part of a RAID array where the information is synced between various different drives, the corrupted file shall be copied on all of the other drives and the harm will be long term. A number of widely used file systems either do not feature real-time checks or do not have high quality ones which can detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where substantial amounts of data are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

We've resolved the problem of silent data corruption on all of our cloud web hosting servers by using the amazing Z file system, or ZFS. The latter is better than other file systems because it is the only one in existence which checks all the files instantly 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 regularly synced between them for redundancy. ZFS regularly examines the checksum of all files and when any file is detected as damaged, it is replaced instantly with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be duplicated on the other NVMes. ZFS requires lots of physical memory in order to perform the real-time checks and the benefit of our cloud web hosting platform is that we use multiple very powerful servers working together. If you host your websites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not encounter any kind of silent data corruption issues whatsoever should you obtain one of our semi-dedicated hosting packages due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums to guarantee that all files are undamaged all the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. Since we store all content on multiple drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 without delay, avoiding any possibility of the damaged copy to be synchronized on the rest of the hard drives. ZFS is the sole file system you can find which uses checksums, which makes it much more reliable than other file systems that are not able to detect silent data corruption and duplicate bad files across hard drives.
