Data corruption is the unintentional modification of a file or the loss of info which usually occurs during reading or writing. The reason could be hardware or software failure, and as a result, a file can become partially or completely corrupted, so it will no longer work correctly as its bits shall be scrambled or missing. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. When this kind of a problem appears and it's not identified by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive which is a part of a RAID array where the data is synced between various different drives, the corrupted file will be copied on all the other drives and the harm will be long term. A number of frequently used file systems either do not feature real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where large volumes of information are kept.

No Data Corruption & Data Integrity in Cloud Website Hosting

If you host your sites in a cloud website hosting account from our company, you do not need to worry about your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the leading-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. Any data that you upload will be saved in a RAID i.e. simultaneously on many SSDs. Many file systems synchronize the files between the different drives using this kind of a setup, but there is no real warranty that a file won't be corrupted. This may happen during the writing process on each drive and afterwards a corrupted copy can be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives right away and in the event that a corrupted file is located, it is swapped with a good copy with the correct checksum from another drive. In this way, your data will continue to be undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you get one of our semi-dedicated hosting packages, you won't have to be concerned about silent data corruption because we use ZFS - a high level file system that checks all the files in real time. Every 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 couple of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens immediately, so there will be no risk for any part of your content at any time. In contrast, alternative file systems perform checks only after a system breakdown, 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 can be replicated on the remaining disks as well and you could lose important information. Because this is not the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
