Data corruption is the damage of information because of various software or hardware problems. When a file gets corrupted, it will no longer function properly, so an app will not start or will give errors, a text file could be partially or entirely 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 identification by the system or an admin, which makes it a serious problem for web hosting servers as failures are more likely to occur on larger in size hard disk drives where large volumes of info are located. When a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it's likely that the damaged file will be treated as an undamaged one and it'll be copied on all drives, making the harm permanent. A huge number of the file systems which operate on web servers these days often are not able to locate corrupted files immediately or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Cloud Web Hosting

We have tackled the matter of silent data corruption on all of our cloud web hosting servers by using the modern Z file system, or ZFS. The latter is superior to other file systems because it is the only one out there that checks all the files in real time by using 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 compares the checksum of all files and in case any file is detected as damaged, it's replaced instantly 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 NVMes. ZFS requires plenty of physical memory in order to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple powerful servers working together. In case you host your Internet sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you acquire one of our semi-dedicated server plans, you won't need to worry about silent file 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. The file will be synchronized 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 when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no danger for any part of your content at any time. In comparison, alternative file systems perform checks after a system malfunction, 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 may be replicated on the remaining drives as well and you can lose critical info. As this isn't the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
