Data corruption is the damage of information due to various software or hardware fails. After a file gets corrupted, it will no longer function properly, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, that makes it a serious problem for hosting servers as problems are very likely to occur on larger in size hard disk drives where considerable volumes of info are kept. In case a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as a standard one and it will be duplicated on all of the drives, making the damage permanent. Lots of the file systems that run on web servers these days often are unable to detect corrupted files in real time or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Website Hosting

We've tackled the issue of silent data corruption on all our cloud website hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one on the market which checks all files in real time by using a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it will be stored on several SSD drives and continually synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as corrupted, it's replaced promptly with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the remaining SSDs. ZFS requires plenty of physical memory to execute the real-time checks and the benefit of our cloud web hosting platform is that we use multiple very powerful servers working together. If you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you obtain one of our semi-dedicated server solutions, you won't have to worry about silent file corruption as we use ZFS - an advanced file system that keeps track of all files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between several SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This happens immediately, so there will be no threat for any part of your content at any time. In comparison, all of the other file systems execute checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy could be replicated on the other drives as well and you could lose precious data. As this isn't the case with ZFS, we warrant the integrity of each file you upload no matter what.
