Data corruption is the unintended modification of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software failure, and for that reason, a file may become partially or completely corrupted, so it'll no longer function correctly since its bits will be scrambled or missing. An image file, for example, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In the event that such an issue appears and it's not recognized by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive that is part of a RAID array where the data is synchronized between various drives, the corrupted file shall be copied on all the other drives and the harm will be permanent. Many commonly used file systems either do not have real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Hosting

We warrant the integrity of the data uploaded in each hosting account that is generated on our cloud platform because we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption using a unique checksum for each and every file. We shall store your data on a number of NVMe drives that operate in a RAID, so the same files will exist on several places at once. ZFS checks the digital fingerprint of all files on all the 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 version from a different drive in the RAID. There's no other file system that uses checksums, so it's possible for data to become silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server using 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 resistant to silent data corruption as all our storage servers make use of the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each file. When you upload content to your account, it will be saved on a couple of redundant drives being employed in a RAID i.e. the files will be the same on all disks. All the copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, and if it detects a mismatch, that would indicate that one of the copies is damaged, it'll replace that file with a good copy from one of the other disks. Even if there is an unforeseen power loss, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, extending the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
