Data corruption is the unintended modification of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file may become partially or completely corrupted, so it'll no longer function as it should because its bits shall be scrambled or lost. An image file, for example, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If this kind of an issue occurs and it is not found by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive which is a part of a RAID array where the data is synced between different drives, the corrupted file shall be replicated on all the other drives and the damage will become permanent. A large number of widely used file systems either do not have real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where huge volumes of info are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
In case you host your websites in a shared web hosting account from our firm, you won't have to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform works with the advanced ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. All data that you upload will be kept in a RAID i.e. simultaneously on many different NVMe drives. All the file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file won't be corrupted. This can occur throughout the writing process on each drive and then a damaged copy may be copied on the other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives live and if a corrupted file is discovered, it is swapped with a good copy with the correct checksum from some other drive. This way, your info will continue to be intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be protected against silent data corruption as all our storage servers make use of the innovative ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of every single file. When you upload content to your account, it'll be kept on a couple of redundant drives operating in a RAID i.e. the files shall be the same on all disk drives. All copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, and if it discovers a mismatch, which would indicate that one of the copies is corrupted, it will swap that file with a healthy copy from one of the other drives. Even if there is an unforeseen blackout, 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 after some failure, prolonging the time needed for the server to get back online. ZFS is the file system which can truly protect your content from silent data corruption.
