Data corruption is the unintended change of a file or the losing of info which usually occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file could become partially or completely corrupted, so it'll no longer function as it should as its bits will be scrambled or lost. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In case this kind of a problem appears and it isn't found by the system or by an admin, the data will be corrupted silently and when this happens on a drive that is part of a RAID array where the data is synced between various different drives, the corrupted file shall be replicated on all other drives and the harm will become permanent. A number of commonly used file systems either don't offer real-time checks or don't have high quality ones which can detect a problem before the damage is done, so silent data corruption is a very common problem on web hosting servers where large volumes of info are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the info uploaded in every cloud website hosting
account that is made on our cloud platform as we use the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption using a unique checksum for each file. We will store your info on a number of SSD drives which operate in a RAID, so the same files will be available on several places at once. ZFS checks the digital fingerprint of all of the files on all 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 a healthy version from some other drive in the RAID. There's no other file system that uses checksums, so it is possible for data to be silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you do not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you acquire one of our semi-dedicated hosting
plans, you will not have to worry about silent file corruption because we use ZFS - a high level file system which monitors all files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between several SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no risk for any part of your content at any moment. In comparison, alternative file systems perform checks after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you could lose critical info. As this is not the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
