Data corruption is the damage of data because of various software or hardware problems. After a file gets damaged, it will no longer work correctly, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, that makes it a serious problem for web hosting servers as failures are more likely to happen on larger in size hard drives where large volumes of information are stored. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a good one and it'll be copied on all of the drives, making the harm permanent. Lots of the file systems which operate on web servers nowadays often cannot find corrupted files right away or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Shared Web Hosting
We have dealt with the issue of silent data corruption on all our shared web hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is better than other file systems because it is the only one out there that checks all the files immediately by using a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and constantly synchronized between them for redundancy. ZFS constantly compares 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 some other disk. As this happens in real time, there is no risk that a damaged file may remain or may be duplicated on the rest of the NVMes. ZFS requires a lot of physical memory in order to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple powerful servers working together. In case you host your Internet sites with us, your info will be intact no matter what.
