Data corruption is the accidental change of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file may become partially or entirely corrupted, so it will no longer function as it should as its bits shall be scrambled or missing. An image file, for example, will no longer show a true image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If such an issue appears and it isn't identified by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive which is part of a RAID array where the data is synchronized between various drives, the corrupted file shall be duplicated on all of the other drives and the damage will become permanent. A large number of widely used file systems either do not offer real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common problem on hosting servers where substantial amounts of info are stored.

No Data Corruption & Data Integrity in Web Hosting

We guarantee the integrity of the data uploaded in every single web hosting account which is generated on our cloud platform because we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption through a unique checksum for every single file. We shall store your data on multiple SSD drives that work in a RAID, so identical files will be present on several places at the same time. ZFS checks the digital fingerprint of all files on all drives in real time and in case the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy version from another drive within the RAID. No other file system uses checksums, so it is possible for data to be silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption since all our storage servers use the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives operating in a RAID i.e. the files shall be the same across all disks. All copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, and if it registers a mismatch, that will indicate that one of the copies is corrupted, it will substitute that file with a healthy copy from one of the other drives. Even if there's an unforeseen power loss, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check which other file systems perform following some malfunction, prolonging the time needed for the server to go back online. ZFS is the file system that can truly protect your content from silent data corruption.
