Data corruption is the unintended transformation of a file or the loss of information that often occurs during reading or writing. The reason could be hardware or software fail, and due to this fact, a file can become partially or fully corrupted, so it'll no longer function as it should because its bits shall be scrambled or lacking. An image file, for instance, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In case such a problem occurs and it's not found by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive that is part of a RAID array where the information is synchronized between different drives, the corrupted file shall be replicated on all other drives and the damage will be long term. A large number of widely used file systems either don't have real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a common issue on web hosting servers where huge amounts of information are kept.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your sites in a shared hosting account with our company, you won't need to worry about your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. All info that you upload will be saved in a RAID i.e. simultaneously on numerous NVMes. Many file systems synchronize the files between the different drives using such a setup, but there is no real guarantee that a file will not get corrupted. This can occur throughout the writing process on each drive and afterwards a bad copy may be copied on all other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives right away and when a corrupted file is discovered, it is substituted with a good copy with the correct checksum from some other drive. In this way, your information will stay intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption because all our storage servers work with the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, 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 being employed in a RAID i.e. the files shall be the same on all 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 discovers a mismatch, that will indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other disks. Even if there's an unexpected power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some breakdown, prolonging the time needed for the server to go back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
