Data corruption is the accidental transformation of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file may become partially or completely corrupted, so it will no longer work as it should because its bits shall be scrambled or lacking. An image file, for example, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In case this kind of an issue appears and it isn't found by the system or by an admin, the data will get corrupted silently and when this happens on a drive that is part of a RAID array where the info is synced between various drives, the corrupted file will be replicated on all other drives and the harm will become long term. Numerous frequently used file systems either don't feature 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 rather common problem on web hosting servers where substantial amounts of information are kept.
No Data Corruption & Data Integrity in Shared Website Hosting
We warrant the integrity of the information uploaded in every single shared website hosting
account which is made on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each file. We'll store your data on a number of SSD drives that operate in a RAID, so the very 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 differs from what it should be, the file system swaps that file with an undamaged version from some other drive within the RAID. There's no other file system which uses checksums, so it's possible for data to become silently corrupted and the bad file to be replicated on all drives with time, but since that can never happen on a server using ZFS, you do not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you obtain one of our semi-dedicated hosting
solutions, you won't need to be concerned about silent data corruption because we use ZFS - an advanced file system which checks all of the files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no threat for any part of your content at any time. In contrast, all the other file systems execute checks after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a bad copy may be replicated on the other disks as well and you may lose critical information. Because this isn't the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
