No Data Corruption & Data Integrity
See what No Data Corruption & Data Integrity is and how it can be good for the files within your hosting account.
Data corruption is the damage of information caused by various software or hardware problems. Once a file is corrupted, it will no longer work correctly, so an app will not start or shall give errors, a text file can be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, that makes it a significant problem for hosting servers as failures are more likely to occur on bigger hard drives where substantial volumes of information are placed. In case a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and it'll be copied on all the drives, making the harm permanent. A huge number of the file systems that operate on web servers these days often are not able to identify corrupted files immediately or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Shared Website Hosting
We have dealt with the matter of silent data corruption on our shared website hosting servers by using the cutting-edge Z file system, or ZFS. The latter is superior to other file systems since it is the only one on the market that checks all the files in real time by employing a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it'll be stored on several NVMe drives and constantly synchronized between them for redundancy. ZFS regularly examines the checksum of all files and in case any file is detected as corrupted, it's replaced immediately with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the other NVMes. ZFS requires a lot of physical memory to execute the real-time checks and the advantage of our cloud hosting platform is that we use multiple powerful servers working together. If you host your sites with us, your info will be intact no matter what.
