Data corruption is the accidental change of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software malfunction, and consequently, a file may become partially or completely corrupted, so it will no longer work properly since its bits will be scrambled or missing. An image file, for example, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. When this kind of a problem occurs and it's not found by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the information is synced between various different drives, the corrupted file shall be reproduced on all other drives and the harm will be permanent. A number of frequently used file systems either do not offer real-time checks or don't have high quality ones that can detect an issue before the damage is done, so silent data corruption is a very common problem on hosting servers where huge amounts of info are kept.
No Data Corruption & Data Integrity in Cloud Web Hosting
In case you host your Internet sites in a cloud web hosting account with our company, you don't need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform uses the amazing ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. All the info that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. All of the file systems synchronize the files between the different drives with such a setup, but there is no real guarantee that a file will not get corrupted. This can occur at the time of the writing process on any drive and afterwards a bad copy may be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all drives in real time and when a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. In this way, your data will remain intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you get one of our semi-dedicated hosting solutions, you won't need to be concerned about silent file corruption as we use ZFS - an advanced file system which monitors all the 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. This file will be synchronized between a number of SSD drives for redundancy, so if one drive fails, the other ones will take control. 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 happens instantly, so there will be no risk for any part of your content at any moment. By comparison, all of the other file systems execute checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a bad copy may be replicated on the other drives as well and you may lose precious data. Since this isn't the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
