Data corruption is the accidental change of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software malfunction, and as a consequence, a file may become partially or fully corrupted, so it will no longer function properly since its bits shall be scrambled or lacking. An image file, for example, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In the event that this kind of an issue occurs and it is not noticed by the system or by an admin, the data will get corrupted silently and when this happens on a drive that is a part of a RAID array where the data is synchronized between various drives, the corrupted file shall be replicated on all other drives and the harm will become long term. Numerous widely used file systems either don't have real-time checks or do not have high quality ones which can detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where huge volumes of info are stored.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your websites in a cloud website hosting account from our firm, you do not need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. All info that you upload will be saved in a RAID i.e. simultaneously on multiple NVMe drives. Many file systems synchronize the files between the different drives with such a setup, but there is no real warranty that a file won't get corrupted. This may occur during the writing process on any drive and then a corrupted copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all drives live and in case a corrupted file is located, it's replaced with a good copy with the correct checksum from another drive. That way, your data will remain undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be protected against silent data corruption as all of our storage servers make use of the innovative ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it will be kept on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all drives. All of the copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, so if it identifies a mismatch, which would indicate that one of the copies is corrupted, it will replace that file with a good copy from one of the other disks. Even if there's a sudden power loss, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, prolonging the time needed for the server to go back online. ZFS is the sole file system which can really protect your content from silent data corruption.
