Data corruption is the unintended modification of a file or the losing of info which often occurs during reading or writing. The reason could be hardware or software fail, and as a consequence, a file may become partially or fully corrupted, so it will no longer function correctly since its bits will be scrambled or missing. An image file, for instance, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. When this kind of an issue 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 disk drive that's part of a RAID array where the info is synchronized between various drives, the corrupted file shall be duplicated on all the other drives and the damage will become long term. Numerous popular file systems either don't have real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common issue on hosting servers where large amounts of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

We have dealt with the issue of silent data corruption on all of our cloud hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is better than other file systems since it is the only one out there that checks all the files in real time by using a checksum - a digital identifier which is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and regularly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and when any file is detected as damaged, it is replaced immediately 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 other SSDs. ZFS requires plenty of physical memory in order to execute the real-time checks and the advantage of our cloud website hosting platform is that we use multiple very powerful servers working together. In case you host your websites with us, your information will be intact no matter what.
