Data corruption is the unintentional transformation of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software malfunction, and consequently, a file can become partially or entirely corrupted, so it'll no longer function properly because its bits will be scrambled or missing. An image file, for instance, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. 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 part of a RAID array where the information is synchronized between various drives, the corrupted file will be reproduced on all the other drives and the damage will become long term. Many widely used file systems either don't feature real-time checks or do not have high quality ones which will detect an issue before the damage is done, so silent data corruption is a very common matter on web hosting servers where large amounts of data are stored.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the data uploaded in any web hosting account that is generated on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption via a unique checksum for each and every file. We will store your data on a number of SSD drives which function in a RAID, so the same files will be present on several places at once. ZFS checks the digital fingerprint of all of the files on all drives in real time and in case the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy version from some other drive inside the RAID. There's no other file system that uses checksums, so it is easy for data to be silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you acquire one of our semi-dedicated server solutions, you will not have to be concerned about silent file corruption as we use ZFS - a high level file system which keeps track of all of the files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between several 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 when it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no risk for any part of your content at any moment. In comparison, other file systems execute checks after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the remaining disks as well and you may lose critical information. Since this is not the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
