Data corruption is the unintentional transformation of a file or the losing of info which usually occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file can become partially or entirely corrupted, so it will no longer function correctly since its bits shall be scrambled or lost. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In case such an issue appears and it is not noticed by the system or by an admin, the data will get corrupted silently and if this happens on a drive that is a part of a RAID array where the data is synced between different drives, the corrupted file will be duplicated on all of the other drives and the damage will be permanent. Many widespread file systems either don't have real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a rather common problem on hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

We warrant the integrity of the info uploaded in each cloud web hosting account that is generated on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption via a unique checksum for each and every file. We will store your info on multiple NVMe drives which work in a RAID, so exactly the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file is different from what it has to be, the file system swaps that file with a healthy copy from a different drive from the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you obtain one of our semi-dedicated hosting plans, you won't have to be concerned about silent file corruption as we use ZFS - an advanced file system that keeps track of all of the 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. That file will be synced between several 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 if it detects a damaged 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 moment. In contrast, other file systems carry out 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 rest of the drives as well and you can lose important info. Because this is not the case with ZFS, we warrant the integrity of each file you upload no matter what.
