Data corruption is the unintentional modification of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software malfunction, and as a result, a file may become partially or entirely corrupted, so it'll no longer work correctly because its bits shall be scrambled or lacking. An image file, for example, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. In the event that such a problem appears and it isn't identified by the system or by an admin, the data will get corrupted silently and in case this happens on a drive which is part of a RAID array where the info is synchronized between various drives, the corrupted file will be copied on all the other drives and the damage will become permanent. Many widely used file systems either do not offer real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a very common problem on internet hosting servers where large volumes of data are kept.
No Data Corruption & Data Integrity in Hosting
We guarantee the integrity of the info uploaded in each hosting
account that is created 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 avert silent data corruption thanks to a unique checksum for every single file. We will store your information on multiple SSD drives which function in a RAID, so the very same files will be accessible on several places at once. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy version from another drive inside the RAID. There's no other file system which uses checksums, so it is easy for data to get silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you obtain one of our semi-dedicated hosting
packages, you won't have to worry about silent data corruption since we use ZFS - an advanced file system that checks all of the files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between several SSD drives for redundancy, so if a drive fails, the other ones will take over. 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 happens immediately, so there will be no danger for any part of your content at any time. In contrast, other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the remaining drives as well and you may lose important info. Because this isn't the case with ZFS, we can guarantee the integrity of each file you upload no matter what.
