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 malfunction, and because of this, a file could become partially or completely corrupted, so it will no longer work properly because its bits shall 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 since its content will be unreadable, etcetera. If this kind of a problem appears and it isn't recognized by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive which is part of a RAID array where the data is synchronized between various different drives, the corrupted file will be reproduced on all the other drives and the damage will be long term. Many widespread file systems either do not offer real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a rather common problem on hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the info uploaded in every single shared hosting account that is created on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for each and every file. We'll store your data on a large number of NVMe drives that function in a RAID, so the same files will be available on several places at the same time. ZFS checks the digital fingerprint of all files on all of the 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 an undamaged copy from a different drive within the RAID. No other file system uses checksums, so it's possible for data to become silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you will not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any risk of files getting damaged silently because the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its basic advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we keep all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. In the event that there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and since it happens instantly, there's no chance that a corrupted copy can remain on our website hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems use such checks and furthermore, even during a file system check following a sudden blackout, none of them will discover silently corrupted files. In contrast, ZFS won't crash after a blackout and the constant checksum monitoring makes a lenghty file system check unneeded.
