Data corruption is the damage of info due to various hardware or software failures. Once a file is damaged, it will no longer work correctly, so an app will not start or will give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as problems are very likely to occur on larger hard drives where vast volumes of info are stored. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as a healthy one and it'll be duplicated on all of the drives, making the harm permanent. Lots of the file systems that operate on web servers today often cannot detect corrupted files right away or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Shared Website Hosting

We have tackled the matter of silent data corruption on all of our shared website hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems as it is the only one on the market which checks all of the files instantly by employing a checksum - a digital identifier that's unique for each file. When you upload content to your account, it will be stored on several NVMe drives and constantly synchronized between them for redundancy. ZFS regularly compares the checksum of all files and in case any file is detected as damaged, it's replaced promptly 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 copied on the rest of the NVMes. ZFS requires plenty of physical memory in order to carry out the real-time checks and the benefit of our cloud hosting platform is that we use multiple powerful servers working together. In case you host your sites with us, your data will be undamaged no matter what.
