Data corruption is the damage of information due to various hardware or software fails. When a file gets damaged, it will no longer function accurately, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, which makes it a significant problem for hosting servers as fails are much more likely to occur on larger hard disk drives where vast volumes of info are kept. If a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as a regular one and will be duplicated on all drives, making the harm permanent. A lot of the file systems that run on web servers nowadays often are unable to recognize corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

We've tackled the problem of silent data corruption on our cloud hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems as it is the only one in existence which checks all of the files right away by using a checksum - a digital identifier that is unique for each file. When you upload content to your account, it will be stored on several NVMe drives and frequently synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and when any file is detected as damaged, it's replaced right away 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 duplicated on the remaining NVMes. ZFS needs a lot of physical memory in order to perform the real-time checks and the advantage of our cloud web hosting platform is that we take advantage of multiple very powerful servers working together. If you host your sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you go for one of our semi-dedicated server packages, you will not have to be concerned about silent data corruption because we use ZFS - a high level file system which keeps track of all the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a number 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 if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no risk for any part of your content at any time. In contrast, other file systems carry out checks after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a bad copy could be replicated on the remaining drives as well and you may lose crucial information. Because this isn't the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
