Data corruption is the accidental change of a file or the losing of information that often occurs during reading or writing. The reason can be hardware or software malfunction, and consequently, a file could become partially or fully corrupted, so it'll no longer work correctly since its bits will be scrambled or lost. An image file, for example, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. In the event that this kind of an issue appears and it's not identified by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive that is part of a RAID array where the data is synchronized between different drives, the corrupted file will be copied on all other drives and the harm will become permanent. Many widespread file systems either don't offer real-time checks or do not have good ones which will detect a problem before the damage is done, so silent data corruption is a very common issue on internet hosting servers where huge volumes of information are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your Internet sites in a cloud web hosting account with our firm, you do not need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. Any kind of info 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 different drives with such a setup, but there is no real warranty that a file will not be corrupted. This can happen at the time of the writing process on any drive and then a damaged 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 the drives immediately and when a corrupted file is found, it is swapped with a good copy with the correct checksum from some other drive. In this way, your information will continue to be undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you acquire one of our semi-dedicated hosting solutions, you will not need to worry about silent data corruption as we use ZFS - an advanced file system which keeps track of all the files in real time. Each time you upload a file to your website 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 one drive fails, the other ones will take control. 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 is done right away, so there will be no risk for any part of your content at any time. By comparison, all the other file systems perform checks after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you can lose crucial data. Because this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
