Data corruption is the unintentional transformation of a file or the losing of info which often occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file may become partially or fully corrupted, so it'll no longer function as it should since its bits shall be scrambled or lacking. An image file, for example, will no longer show an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If this kind of an issue appears and it isn't noticed 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 data is synced between various different drives, the corrupted file will be duplicated on all other drives and the harm will become long term. A number of widespread file systems either don't offer real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common problem on web hosting servers where huge amounts of info are kept.

No Data Corruption & Data Integrity in Cloud Hosting

We've tackled the matter of silent data corruption on our cloud hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is better than other file systems since it is the only one in existence that checks all files instantly by employing a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and constantly synchronized between them for redundancy. ZFS regularly examines the checksum of all files and in the event that any file is detected as damaged, it's replaced right away with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the other SSDs. ZFS requires plenty of physical memory to carry out the real-time checks and the advantage of our cloud hosting platform is that we employ multiple powerful servers working together. If you host your sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you obtain one of our semi-dedicated hosting solutions, you will not have to be concerned about silent data corruption since we use ZFS - an advanced file system that monitors all the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no danger for any part of your content at any moment. By comparison, all of 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 can't detect silently corrupted files, so a corrupted copy can be replicated on the remaining disks as well and you could lose precious data. As this is not the case with ZFS, we're able to warrant the integrity of each file you upload no matter what.
