Data corruption is the unintended modification of a file or the losing of info that often occurs during reading or writing. The reason could be hardware or software fail, and as a consequence, a file may become partially or fully corrupted, so it will no longer work properly because its bits shall 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 for the reason that its content will be unreadable, etcetera. When this kind of an issue appears and it's not found by the system or by an administrator, the data will be corrupted silently and when this happens on a disk drive that's part of a RAID array where the info is synced between various different drives, the corrupted file will be copied on all of the other drives and the damage will become long term. Numerous commonly used file systems either do not feature real-time checks or don't have high quality ones that will detect an issue before the damage is done, so silent data corruption is a very common matter on hosting servers where large volumes of info are kept.
No Data Corruption & Data Integrity in Cloud Hosting
In case you host your websites in a cloud hosting account from our firm, you don't need to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. All the data that you upload will be saved in a RAID i.e. simultaneously on numerous SSD drives. All of the file systems synchronize the files between the separate drives using this type of a setup, but there is no real warranty that a file won't get corrupted. This may happen at the time of the writing process on any drive and then a corrupted copy can be copied on the rest of the drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives immediately and if a corrupted file is located, it's substituted with a good copy with the correct checksum from some other drive. In this way, your data will stay unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you buy one of our semi-dedicated hosting packages, you won't have to be concerned about silent file corruption as we use ZFS - a high level file system that keeps track of all files in real time. Whenever 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 a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no danger for any part of your content at any moment. In contrast, other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you may lose crucial data. Since this isn't the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
