Data corruption is the unintended transformation of a file or the losing of information which usually occurs during reading or writing. The reason may be hardware or software fail, and as a consequence, a file could become partially or entirely corrupted, so it'll no longer work correctly since its bits will be scrambled or lost. An image file, for example, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In the event that this kind of an issue appears and it is not found by the system or by an administrator, the data will become corrupted silently and when this happens on a disk drive which is a part of a RAID array where the information is synchronized between different drives, the corrupted file will be copied on all other drives and the damage will become permanent. Numerous widely used file systems either don't feature 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 matter on hosting servers where substantial volumes of information are kept.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the information uploaded in each web hosting account that is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each file. We'll store your info on a large number of NVMe drives that work in a RAID, so the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with a healthy copy from another drive within the RAID. There's no other file system that uses checksums, so it is easy for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption because all of our storage servers use the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it'll be placed on several redundant drives employed in a RAID i.e. the files will be the same across all drives. All of the copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the copies quickly, and if it identifies a mismatch, that would indicate that one of the copies is damaged, it will swap that file with a healthy copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check which other file systems perform after some malfunction, lengthening the time needed for the server to get back online. ZFS is the sole file system which can really protect your content from silent data corruption.
