Data corruption is the accidental modification of a file or the losing of information that often occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file could become partially or entirely corrupted, so it will no longer work properly as its bits shall be scrambled or missing. An image file, for instance, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When such an issue appears and it is not found by the system or by an administrator, the data will be corrupted silently and when this happens on a drive which is a part of a RAID array where the info is synced between different drives, the corrupted file shall be reproduced on all the other drives and the harm will become permanent. A number of popular file systems either do not offer real-time checks or do not have high quality ones which can detect an issue before the damage is done, so silent data corruption is a very common matter on internet hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Web Hosting

We guarantee the integrity of the information uploaded in every single web hosting account that is created on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We will store your information on multiple SSD drives which function in a RAID, so the same files will be present on several places at the same time. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file is different from what it should be, the file system replaces that file with a healthy copy from a different drive in the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you do not 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 packages, you will not have to worry about silent data corruption since we use ZFS - an advanced file system that checks all the files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between multiple SSD drives for redundancy, so if one 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 damaged copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no threat for any part of your content at any time. In comparison, all of the other file systems execute checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the remaining drives as well and you may lose important info. As this isn't the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
