Data corruption is the unintended change of a file or the loss of info which often occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file may become partially or completely corrupted, so it'll no longer function as it should since its bits will be scrambled or missing. An image file, for example, will no longer present 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. If this kind of an issue occurs and it isn't recognized by the system or by an admin, the data will be corrupted silently and when this happens on a drive that's a part of a RAID array where the data is synchronized between different drives, the corrupted file will be replicated on all the other drives and the damage will become long term. Many commonly used file systems either do not have real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a common problem on web hosting servers where substantial amounts of information are kept.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your sites in a shared hosting account from our firm, you won't have to worry about any of your data ever getting damaged. We can guarantee that since our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. Any data that you upload will be stored in a RAID i.e. simultaneously on many different NVMe drives. Many file systems synchronize the files between the different drives with such a setup, but there's no real guarantee that a file won't be corrupted. This can occur during the writing process on any drive and then a bad copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all the drives live and in case a corrupted file is located, it is substituted with a good copy with the correct checksum from another drive. By doing this, your information 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 protected against silent data corruption as all our storage servers work with the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each and every file. When you upload content to your account, it'll be placed on a couple of redundant drives employed in a RAID i.e. the files will be the same across all disk drives. All of the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, so if it finds a mismatch, which will indicate that one of the copies is damaged, it'll replace that file with a good copy from one of the other disks. Even if there is an unforeseen blackout, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, prolonging the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
