Data corruption is the unintended transformation of a file or the losing of info which usually occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file can become partially or completely corrupted, so it will no longer work correctly because its bits shall be scrambled or missing. An image file, for instance, will no longer show an authentic image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. If such an issue appears and it isn't found by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive that's part of a RAID array where the information is synced between various drives, the corrupted file shall be replicated on all the other drives and the damage will be permanent. A large number of widely used file systems either do not have real-time checks or do not have good ones that will detect an issue before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where huge volumes of info are stored.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the data uploaded in any cloud hosting account which is generated on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption using a unique checksum for every single file. We will store your data on multiple NVMe drives which operate in a RAID, so the very same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file is different from what it should be, the file system swaps that file with a healthy version from some other drive in the RAID. There's no other file system that uses checksums, so it's possible for data to be silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be shielded from silent data corruption since all our storage servers use the advanced ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of each and every file. When you upload content to your account, it'll be kept on a couple of redundant drives employed in a RAID i.e. the files will be the same on all drives. All the copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, and if it detects a mismatch, that will indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other drives. Even if there's an unexpected power failure, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, lengthening the time needed for the server to get back online. ZFS is the sole file system which can really protect your content from silent data corruption.
