Data corruption is the accidental change of a file or the losing of information that usually occurs during reading or writing. The reason may be hardware or software fail, and as a result, a file may become partially or fully corrupted, so it will no longer function as it should as its bits will be scrambled or missing. An image file, for example, will no longer present an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In the event that such an issue occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and when this happens on a drive that's part of a RAID array where the info is synced between various drives, the corrupted file shall be reproduced on all the other drives and the harm will become long term. A number of widespread file systems either don't offer real-time checks or don't have good ones which will detect a problem before the damage is done, so silent data corruption is a very common matter on internet hosting servers where substantial volumes of info are kept.

No Data Corruption & Data Integrity in Cloud Website Hosting

We've dealt with the problem of silent data corruption on our cloud website hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems since it is the only one in existence which checks all of the files right away by employing a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and regularly synced 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 another disk. As this happens in real time, there's no risk that a corrupted file may remain or may be copied on the other SSDs. ZFS requires a lot of physical memory to execute 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 Internet sites with us, your info will be undamaged no matter what.
