Data corruption is the damage of information because of various hardware or software problems. When a file is corrupted, it will no longer work correctly, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for web hosting servers as fails are very likely to occur on larger in size hard drives where considerable volumes of information are stored. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as an undamaged one and it will be duplicated on all drives, making the damage permanent. A huge number of the file systems that run on web servers nowadays often are not able to locate corrupted files immediately or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Website Hosting

We've resolved the matter of silent data corruption on all our website hosting servers by using the hi-tech Z file system, or ZFS. The latter is better than other file systems since it is the only one in existence which checks all the files right away by employing a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several NVMe drives and regularly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as damaged, it's replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the remaining NVMes. ZFS requires a lot of physical memory to carry out the real-time checks and the advantage of our cloud hosting platform is that we take advantage of multiple very powerful servers working together. In case you host your Internet sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you obtain one of our semi-dedicated hosting solutions, you will not have to worry about silent file corruption since 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 website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between a number of NVMe drives for redundancy, so if one 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 right away, so there will be no risk for any part of your content at any moment. By comparison, other file systems perform checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the other drives as well and you may lose important information. As this isn't the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
