Data corruption is the unintended change of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file can become partially or entirely corrupted, so it'll no longer work correctly since its bits shall be scrambled or lacking. An image file, for example, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. If such an issue occurs and it is not found by the system or by an admin, the data will be corrupted silently and if this happens on a drive that's a part of a RAID array where the information is synchronized between different drives, the corrupted file will be replicated on all the other drives and the damage will be long term. Many widely used file systems either don't feature real-time checks or don't have good ones which can detect an issue before the damage is done, so silent data corruption is a common matter on hosting servers where substantial volumes of information are stored.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your sites in a cloud hosting account with our firm, you won't need to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform employs the reliable ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. All of the information that you upload will be stored in a RAID i.e. simultaneously on numerous SSD drives. All of the file systems synchronize the files between the different drives using this kind of a setup, but there is no real warranty that a file will not get corrupted. This may occur during the writing process on each drive and afterwards a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives immediately and in the event that a corrupted file is found, it is swapped with a good copy with the correct checksum from some other drive. By doing this, your info will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you go for one of our semi-dedicated hosting solutions, you will not need to be concerned about silent data corruption because we use ZFS - an advanced file system which monitors all files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between multiple SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no threat for any part of your content at any moment. By comparison, alternative file systems execute checks 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 drives as well and you can lose critical data. Because this is not the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
