Data corruption is the damage of data because of various software or hardware failures. After a file is damaged, it will no longer work accurately, so an application will not start or will give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as failures are very likely to occur on larger hard drives where vast volumes of info are located. In case a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all drives, making the harm permanent. A huge number of the file systems which operate on web servers these days often cannot detect corrupted files immediately 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 problem of silent data corruption on all our shared website hosting servers by using the advanced Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one on the market that checks all files instantly by employing a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and regularly synced between them for redundancy. ZFS constantly compares the checksum of all files and in the event that any file is detected as corrupted, it is replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a corrupted 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. If you host your Internet sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you obtain one of our semi-dedicated server plans, you won't need to be concerned about silent file corruption since we use ZFS - an advanced file system which keeps track of all files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between several NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens in real time, so there will be no risk for any part of your content at any moment. In contrast, all the other file systems carry out checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a bad copy may be replicated on the rest of the disks as well and you can lose crucial data. Since this is not the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
