Data corruption is the accidental transformation of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file could become partially or entirely corrupted, so it'll no longer function properly because its bits will be scrambled or lacking. An image file, for example, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If this kind of a problem occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that's part of a RAID array where the info is synced between various drives, the corrupted file shall be reproduced on all of the other drives and the harm will become long term. Numerous popular file systems either do not feature real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a common issue on web hosting servers where substantial volumes of info are stored.

No Data Corruption & Data Integrity in Shared Website Hosting

We guarantee the integrity of the data uploaded in any shared website hosting account that is made on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption through a unique checksum for each file. We will store your data on a number of NVMe drives that operate in a RAID, so the same files will be available on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from a different drive from the RAID. There's no other file system that uses checksums, so it is possible for data to be silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you purchase one of our semi-dedicated server packages, you will not need to worry about silent file corruption as we use ZFS - a high level file system that keeps track of all the files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between multiple NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no danger for any part of your content at any time. In comparison, all the other file systems carry out checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the remaining drives as well and you could lose critical information. Since this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
