Data corruption is the unintentional change of a file or the loss of info that often occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file can become partially or fully corrupted, so it will no longer work correctly because its bits shall be scrambled or missing. An image file, for example, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. When such an issue appears and it isn't found 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 information is synchronized between different drives, the corrupted file shall be replicated on all other drives and the damage will be long term. Numerous frequently used file systems either do not have real-time checks or don't have good ones which will detect a problem before the damage is done, so silent data corruption is a very common issue on web hosting servers where large amounts of info are stored.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the data uploaded in each and every shared hosting account that is made on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for every single file. We'll store your information on a large number of NVMe drives which work in a RAID, so exactly the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with a healthy copy from some other drive in the RAID. No other file system uses checksums, so it is possible 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 don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you purchase one of our semi-dedicated server plans, you will not need to be concerned about silent file corruption since we use ZFS - an advanced file system that monitors all files in real time. Each 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 a number of NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no risk for any part of your content at any time. In comparison, alternative file systems execute checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the other disks as well and you may lose crucial data. Since this is not the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
