Data corruption is the unintentional change of a file or the losing of info which often occurs during reading or writing. The reason may be hardware or software failure, and because of this, a file can become partially or fully corrupted, so it will no longer work as it should as its bits shall be scrambled or lacking. An image file, for instance, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. If such a problem occurs and it is not noticed 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 synchronized between different drives, the corrupted file will be replicated on all the other drives and the harm will be long term. Numerous commonly used file systems either don't feature real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common issue on hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Hosting

If you host your websites in a hosting account from our firm, you won't have to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform employs the leading-edge ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on a large number of NVMes. Many file systems synchronize the files between the different drives using this kind of a setup, but there is no real warranty that a file will not be corrupted. This may happen throughout the writing process on each drive and then a bad copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all the drives in real time and if a corrupted file is found, it is replaced with a good copy with the correct checksum from some other drive. That way, your data will continue to be unharmed 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 shielded from silent data corruption as all of our storage servers employ the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of every single file. When you upload content to your account, it'll be stored on a couple of redundant drives operating in a RAID i.e. the files shall be the same across 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, so if it registers a mismatch, that would indicate that one of the copies is corrupted, it will substitute that file with a healthy copy from one of the other disks. Even if there's an unforeseen power failure, the data on the servers won't become corrupted and there will not 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 that can truly protect your content from silent data corruption.
