Data corruption is the unintended modification of a file or the losing of information which often occurs during reading or writing. The reason may be hardware or software fail, and because of this, a file could become partially or fully corrupted, so it will no longer function correctly as its bits shall be scrambled or lacking. An image file, for example, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. When this kind of an issue occurs and it is not found by the system or by an administrator, the data will be corrupted silently and when this happens on a drive that's part of a RAID array where the info is synced between various different drives, the corrupted file shall be duplicated on all other drives and the damage will become permanent. A large number of popular file systems either don't offer real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a very common matter on internet hosting servers where substantial amounts of information are kept.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the data uploaded in every website hosting
account that is generated on our cloud platform as we work with 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 a large number of SSD drives which function in a RAID, so the exact same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file differs from what it has to be, the file system replaces that file with an undamaged version from another drive inside the RAID. There's no other file system which uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives with time, but since that 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 Hosting
If you go for one of our semi-dedicated hosting
packages, you will not have to be concerned about silent file corruption since we use ZFS - a high level file system which monitors all files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The 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 of the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This happens in real time, so there will be no threat for any part of your content at any time. In contrast, all of the other file systems perform checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the other disks as well and you could lose precious data. As this isn't the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
