Data corruption is the damage of information caused by various software or hardware fails. When a file is corrupted, it will no longer work correctly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a serious problem for hosting servers as failures are more likely to occur on larger in size hard disks where substantial volumes of info are kept. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a standard one and it will be copied on all of 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 recognize corrupted files immediately or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your sites in a cloud web hosting account from our company, you don't have to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform employs the leading-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on multiple NVMe drives. All the file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file will not be corrupted. This can happen throughout the writing process on each drive and afterwards a corrupted copy may be copied on the rest of the drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all the drives live and in case a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. That way, your info will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you buy one of our semi-dedicated server packages, you will not need to be concerned about silent data corruption as we use ZFS - a high level file system that keeps track of all the files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a number of NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no danger for any part of your content at any moment. In comparison, all of the other file systems perform checks only after a system failure, 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 can be replicated on the rest of the disks as well and you may lose important info. Since this isn't the case with ZFS, we're able to warrant the integrity of each file you upload no matter what.
