Data corruption is the accidental change of a file or the losing of information that often occurs during reading or writing. The reason could be hardware or software failure, and as a result, a file can become partially or completely corrupted, so it'll no longer work as it should as its bits will be scrambled or missing. An image file, for example, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When this kind of an issue occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive which is a part of a RAID array where the info is synchronized between various different drives, the corrupted file shall be replicated on all of the other drives and the harm will be long term. A large number of popular file systems either don't offer real-time checks or don't have good ones which can detect a problem before the damage is done, so silent data corruption is a very common problem on web hosting servers where huge volumes of information are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

We warrant the integrity of the info uploaded in every single cloud web hosting account which is generated on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption via a unique checksum for each and every file. We will store your data on a number of NVMe drives which operate in a RAID, so the very same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and if the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy copy from some other drive in the RAID. There's no other file system which uses checksums, so it is easy for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you get one of our semi-dedicated hosting plans, you won't have to be concerned about silent file corruption as we use ZFS - a high level file system that keeps track of all the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between multiple 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 in case it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no danger for any part of your content at any moment. In comparison, other file systems execute checks only 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 corrupted copy could be replicated on the remaining disks as well and you may lose crucial data. As this isn't the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
