Data corruption is the unintended transformation of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software malfunction, and consequently, a file could become partially or entirely corrupted, so it'll no longer function as it should since its bits shall be scrambled or lacking. An image file, for instance, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etc. When this kind of an issue occurs and it isn't recognized by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive that's part of a RAID array where the info is synchronized between different drives, the corrupted file shall be duplicated on all other drives and the damage will become permanent. A large number of frequently used file systems either don't have real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a very common matter on web hosting servers where huge amounts of data are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

We warrant the integrity of the info uploaded in each shared web hosting account that is created on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption using a unique checksum for each file. We will store your info on a number of NVMe drives which operate in a RAID, so the exact same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from another drive inside the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you will not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption as all of our storage servers work with the advanced ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to ensure the integrity of every single file. When you upload content to your account, it will be saved on a couple of redundant drives in a RAID i.e. the files shall be the same across all disks. All copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, so if it finds a mismatch, that will indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other disks. Even if there's a sudden 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 following some failure, lengthening the time needed for the server to get back online. ZFS is the only file system which can truly protect your content from silent data corruption.
