Data corruption is the unintended transformation of a file or the loss of information which often occurs during reading or writing. The reason may be hardware or software failure, and as a result, a file could become partially or entirely corrupted, so it will no longer work properly because its bits shall be scrambled or missing. An image file, for example, will no longer display 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. In case this kind of an issue occurs and it's not found by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive that is part of a RAID array where the data is synchronized between various drives, the corrupted file will be reproduced on all the other drives and the damage will be long term. Many widely used file systems either do not have real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on web hosting servers where huge amounts of info are kept.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the data uploaded in every web hosting account which is generated on our cloud platform as we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption using a unique checksum for each file. We will store your information on a number of NVMe drives which operate in a RAID, so the exact same files will exist on several places at the same time. 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 is different from what it should be, the file system replaces that file with a healthy version from some other drive within 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 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 info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption because all our storage servers work with the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each file. When you upload content to your account, it'll be saved on a couple of redundant drives in a RAID i.e. the files shall be the same on all drives. All the copies of a particular file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, so if it finds a mismatch, which would indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other disks. Even if there's an unexpected blackout, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check which other file systems perform following some failure, extending the time needed for the server to go back online. ZFS is the file system which can really protect your content from silent data corruption.
