Data corruption is the damage of info due to various software or hardware fails. Once a file gets corrupted, it will no longer work accurately, 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 and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, that makes it a serious problem for hosting servers as fails are very likely to happen on bigger hard disk drives where large volumes of info are stored. If a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it's likely that the bad file will be treated as an ordinary one and it'll be copied on all of the drives, making the harm permanent. A huge number of the file systems which run on web servers today often are unable to identify corrupted files in real time or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Web Hosting

We've resolved the issue of silent data corruption on our web hosting servers by using the hi-tech 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 the 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 will be stored on several NVMe drives and constantly synced between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as corrupted, it's replaced instantly 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 copied on the rest of the NVMes. ZFS requires lots of physical memory in order to execute the real-time checks and the advantage of our cloud web hosting platform is that we employ multiple powerful servers working together. In case you host your Internet sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you purchase one of our semi-dedicated hosting solutions, you will not have to worry about silent data corruption because we use ZFS - a high level file system that monitors all files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a couple of NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no threat for any part of your content at any time. In contrast, alternative file systems execute checks after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a corrupted copy can be replicated on the rest of the disks as well and you could lose critical information. As this isn't the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
