Data corruption is the unintended change of a file or the losing of info that often occurs during reading or writing. The reason may be hardware or software failure, and for that reason, a file may become partially or fully corrupted, so it will no longer function as it should since its bits will be scrambled or lacking. An image file, for instance, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. When this kind of an issue occurs and it is not 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 a part of a RAID array where the info is synced between various drives, the corrupted file will be replicated on all other drives and the harm will become long term. A number of widely used file systems either don't offer 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 matter on web hosting servers where large volumes of information are stored.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the information uploaded in any shared hosting account that is generated on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption via a unique checksum for every single file. We will store your info on a large number of NVMe drives which function in a RAID, so the exact same files will be present on several places at the same time. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file differs from what it needs to be, the file system swaps that file with a healthy copy from another drive in the RAID. There's no other file system which uses checksums, so it is easy 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 using ZFS, you won't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption as all our storage servers use the innovative ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it will be saved on a couple of redundant drives employed in a RAID i.e. the files will be the same across all disk drives. All copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, so if it registers a mismatch, which will indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other drives. Even if there's an unexpected blackout, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, prolonging the time needed for the server to go back online. ZFS is the sole file system that can truly protect your content from silent data corruption.
