Data corruption is the unintentional modification of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software failure, and as a result, a file could become partially or entirely corrupted, so it'll no longer work properly because its bits shall be scrambled or missing. An image file, for example, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In the event that this kind of an issue appears and it isn't recognized by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive that is a part of a RAID array where the information is synced between various drives, the corrupted file shall be duplicated on all the other drives and the damage will be permanent. A large number of frequently used file systems either don't offer 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 common problem on hosting servers where substantial amounts of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the data uploaded in every single cloud hosting account that is created on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption via a unique checksum for each file. We'll store your info on a large number of SSD drives which operate in a RAID, so the very same files will be available on several places at the same time. ZFS checks the digital fingerprint of all files on all drives in real time and in case the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from a different drive from the RAID. There's no other file system which uses checksums, so it is possible for data to become silently damaged and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you get one of our semi-dedicated server packages, you will not have to be concerned about silent data corruption because we use ZFS - a high level file system which monitors all the files in real time. Every 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 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 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 right away, so there will be no risk for any part of your content at any moment. In comparison, all the other file systems perform checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the rest of the disks as well and you may lose critical information. Since this isn't the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
