Data corruption is the unintended transformation of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file may become partially or completely corrupted, so it will no longer function as it should because its bits will be scrambled or lost. 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 since its content will be unreadable, and so on. In the event that this kind of an issue appears and it's not noticed by the system or by an administrator, the data will become corrupted silently and when this happens on a disk drive that is a part of a RAID array where the data is synced between different drives, the corrupted file will be copied on all the other drives and the damage will become long term. A large number of popular file systems either do not feature real-time checks or don't have high quality ones that will detect an issue before the damage is done, so silent data corruption is a rather common problem on web hosting servers where large volumes of data are kept.

No Data Corruption & Data Integrity in Shared Web Hosting

We warrant the integrity of the information uploaded in each shared web hosting account which is created on our cloud platform as we use the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption thanks to a unique checksum for every single file. We will store your info on a large number of NVMe drives that work in a RAID, so the exact same files will be present on several places at once. ZFS checks the digital fingerprint of all files on all drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy version from another drive from the RAID. There's no other file system that uses checksums, so it is possible for data to get silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption since all of our storage servers employ the effective ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be kept on several redundant drives working in a RAID i.e. the files will be the same on all disk drives. All the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, so if it detects a mismatch, that would indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other disks. Even if there is a sudden power loss, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, prolonging the time needed for the server to go back online. ZFS is the sole file system which can really protect your content from silent data corruption.
