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 fail, and for that reason, a file can become partially or completely corrupted, so it will no longer work correctly because its bits will be scrambled or lacking. An image file, for instance, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If such an issue appears and it's not identified by the system or by an administrator, the data will be corrupted silently and when this happens on a drive which is part of a RAID array where the info is synced between different drives, the corrupted file will be reproduced on all the other drives and the harm will be long term. Numerous frequently used file systems either do not offer real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a very common issue on hosting servers where substantial amounts of data are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the info uploaded in every single shared web hosting account that is created on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption via a unique checksum for each and every file. We shall store your information on a number of SSD drives that function in a RAID, so identical files will be available on several places at the same time. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file differs from what it has to be, the file system replaces that file with an undamaged version from another drive from the RAID. There's no other file system that uses checksums, so it's easy 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 won't have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be protected against silent data corruption because all of our storage servers employ the effective ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order 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 working in a RAID i.e. the files shall be the same on all disks. All of the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, so if it discovers a mismatch, that will indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other disks. Even if there's an unexpected power loss, the data on the servers will not be 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 that can really protect your content from silent data corruption.
