Data corruption is the unintentional transformation of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software fail, and due to this fact, a file can become partially or completely corrupted, so it will no longer function correctly because its bits shall be scrambled or missing. An image file, for instance, will no longer display an accurate 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. In case such an issue occurs and it's not found by the system or by an administrator, the data will be corrupted silently and when this happens on a disk drive which is part of a RAID array where the data is synced between different drives, the corrupted file shall be reproduced on all of the other drives and the damage will become permanent. Numerous frequently used file systems either do not have real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a common issue on web hosting servers where large volumes of info are kept.

No Data Corruption & Data Integrity in Hosting

We guarantee the integrity of the data uploaded in each hosting account which is generated on our cloud platform as we work with the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each and every file. We shall store your info on a number of SSD drives that function in a RAID, so exactly the same files will be available on several places at once. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and if the checksum of any file is different from what it needs to be, the file system replaces that file with an undamaged version from another drive in the RAID. There's no other file system that uses checksums, so it is easy for data to become silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you get one of our semi-dedicated hosting plans, you will not need to be concerned about silent data corruption as we use ZFS - a high level file system that monitors all of the files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced 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 when it detects a damaged 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 time. In comparison, alternative file systems carry out checks only after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the rest of the disks as well and you can lose critical info. Because this isn't the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
