Data corruption is the accidental change of a file or the loss of information which often occurs during reading or writing. The reason may be hardware or software malfunction, and due to this fact, a file can become partially or completely corrupted, so it'll no longer function correctly since its bits shall be scrambled or lacking. An image file, for example, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In case this kind of a problem occurs and it isn't noticed by the system or by an admin, the data will get corrupted silently and in case this happens on a drive that's part of a RAID array where the information is synced between various different drives, the corrupted file will be duplicated on all of the other drives and the damage will be long term. A large number of commonly used file systems either don't offer real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where huge volumes of information are kept.

No Data Corruption & Data Integrity in Website Hosting

If you host your sites in a website hosting account from our company, you won't have to worry about any of your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform employs the amazing ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All of the data that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. All file systems synchronize the files between the different drives using this type of a setup, but there is no real guarantee that a file will not be corrupted. This may happen during the writing process on any drive and then a bad copy can be copied on the other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all of the drives in real time and in the event that a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. That way, your information will remain undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you acquire one of our semi-dedicated server plans, you won't have to be concerned about silent file corruption as 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 a number of SSD drives for redundancy, so if a 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 another drive. This happens immediately, so there will be no threat for any part of your content at any moment. In contrast, other file systems execute checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you can lose precious data. Because this is not the case with ZFS, we are able to guarantee the integrity of each and every file you upload no matter what.
