Data corruption is the unintentional transformation of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software malfunction, and consequently, a file may become partially or entirely corrupted, so it'll no longer work as it should because its bits will be scrambled or lacking. An image file, for instance, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In case such an issue occurs and it is not identified by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive that's part of a RAID array where the data is synced between different drives, the corrupted file shall be duplicated on all the other drives and the damage will become long term. A large number of commonly used file systems either don't feature real-time checks or do not 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 Web Hosting

We warrant the integrity of the data uploaded in each cloud web hosting account that is created on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption using a unique checksum for each file. We will store your information on multiple SSD drives which operate in a RAID, so the very same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with an undamaged version from some other drive inside the RAID. There's no other file system which uses checksums, so it is possible for data to become silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you acquire one of our semi-dedicated hosting packages, you will not have to worry about silent file corruption because we use ZFS - a high level file system that keeps track of all of 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. That file will be synced between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and when it detects a corrupted 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. In contrast, all of the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a bad copy can be replicated on the rest of the drives as well and you could lose critical data. As this isn't the case with ZFS, we can guarantee the integrity of each file you upload no matter what.
