Data corruption is the damage of data because of various hardware or software failures. After a file is damaged, it will no longer function accurately, so an app will not start or will give errors, a text file will be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an administrator, which makes it a significant problem for website hosting servers as failures are much more likely to occur on larger hard disks where large volumes of info are located. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it is 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 lot of the file systems that operate on web servers today often are not able to locate corrupted files right away or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Website Hosting

We have resolved the problem of silent data corruption on all our shared website hosting servers by using the advanced Z file system, or ZFS. The latter is better than other file systems as it is the only one out there which checks all the files immediately by employing a checksum - a digital identifier that is unique for each and every 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 compares the checksum of all files and when any file is detected as damaged, it is replaced right away 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 copied on the remaining NVMes. ZFS requires plenty of physical memory in order to perform the real-time checks and the benefit of our cloud website hosting platform is that we take advantage of multiple powerful servers working together. If you host your Internet sites with us, your information will be intact no matter what.
