Data corruption is the unintended modification of a file or the loss of information which usually occurs during reading or writing. The reason can be hardware or software fail, and due to this fact, a file could become partially or entirely corrupted, so it will no longer work as it should because its bits will be scrambled or lacking. An image file, for instance, will no longer display an actual image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. If this kind of an issue appears and it isn't recognized by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive that's a part of a RAID array where the info is synced between various different drives, the corrupted file will be replicated on all other drives and the damage will be long term. A large number of widespread file systems either do not offer 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 matter on web hosting servers where huge amounts of data are stored.

No Data Corruption & Data Integrity in Hosting

We guarantee the integrity of the data uploaded in every hosting account that is created on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption thanks to a unique checksum for each file. We will store your information on multiple NVMe drives that operate in a RAID, so identical files will exist on several places at once. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file differs from what it needs to 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's easy for data to get silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you obtain one of our semi-dedicated hosting plans, you will not have to worry about silent file corruption because we use ZFS - an advanced file system which checks all the files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a number of NVMe drives for redundancy, so if a 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 corrupted copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no threat for any part of your content at any time. In contrast, all the other file systems carry out checks after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy may be replicated on the other drives as well and you can lose precious info. Because this isn't the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
