Data corruption is the unintentional modification of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software failure, and for that reason, a file can become partially or fully corrupted, so it will no longer work correctly because its bits will be scrambled or lacking. An image file, for example, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. When such an issue appears and it is not recognized by the system or by an administrator, the data will become corrupted silently and when this happens on a drive that is part of a RAID array where the info is synced between different drives, the corrupted file shall be duplicated on all other drives and the harm will become permanent. A large number of widespread file systems either do not have 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 common problem on web hosting servers where large amounts of data are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the information uploaded in every single cloud website hosting
account which is made on our cloud platform because we work with the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for each and every file. We shall store your data on a number of SSD drives that work in a RAID, so the exact same files will exist on several places concurrently. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with a healthy copy from a different drive in the RAID. There's no other file system that uses checksums, so it is easy for data to become silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you acquire one of our semi-dedicated hosting
packages, you will not have to be concerned about silent file corruption as we use ZFS - an advanced file system which checks all of the files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between multiple SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all 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 right away, so there will be no danger for any part of your content at any moment. In contrast, all of the other file systems perform checks only after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the rest of the disks as well and you may lose important data. As this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
