Data corruption is the unintentional transformation of a file or the losing of information which often occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file may become partially or completely corrupted, so it'll no longer work as it should because its bits will be scrambled or lost. An image file, for instance, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. If such an issue occurs and it is not noticed by the system or by an administrator, the data will become corrupted silently and when this happens on a drive that is part of a RAID array where the data is synchronized between different drives, the corrupted file will be duplicated on all the other drives and the harm will be long term. Many popular file systems either do not have real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common problem on web hosting servers where substantial amounts of info are kept.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the information uploaded in each and every web hosting account that is generated on our cloud platform because we work with the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption using a unique checksum for every single file. We shall store your information on multiple NVMe drives which function in a RAID, so identical files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file is different from what it has to be, the file system replaces that file with a healthy copy from some other drive within the RAID. No other file system uses checksums, so it's easy for data to get silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you buy one of our semi-dedicated server plans, you will not have to be concerned about silent data corruption since we use ZFS - a high level file system that checks all files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all 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 immediately, so there will be no danger for any part of your content at any time. In comparison, all of the other file systems execute checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a bad copy may be replicated on the other drives as well and you may lose critical info. Since this isn't the case with ZFS, we can warrant the integrity of each and every file you upload no matter what.
