Data corruption is the unintentional modification of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software fail, and for that reason, a file can become partially or fully corrupted, so it'll no longer work properly because its bits will be scrambled or lacking. An image file, for example, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In case this kind of a problem occurs and it's not identified by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that's a part of a RAID array where the data is synced between various different drives, the corrupted file will be replicated on all other drives and the harm will become long term. A large number of frequently used file systems either don't 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 very common matter on internet hosting servers where large volumes of information are stored.
No Data Corruption & Data Integrity in Shared Website Hosting
We've resolved the matter of silent data corruption on all our shared website hosting servers by using the amazing Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one in existence which checks all of the files instantly by using a checksum - a digital identifier which is unique for each file. When you upload content to your account, it will be stored on several NVMe drives and regularly synced between them for redundancy. ZFS constantly compares the checksum of all files and in case any file is detected as corrupted, it is replaced instantly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be duplicated on the rest of the NVMes. ZFS requires lots of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we take advantage of multiple very powerful servers working together. In case you host your Internet sites with us, your info will be undamaged no matter what.
