No Data Corruption & Data Integrity
Find out what No Data Corruption & Data Integrity is and how it could be beneficial for the files in your web hosting account.
Data corruption is the unintended transformation of a file or the loss of info that usually occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file can become partially or entirely corrupted, so it'll no longer work properly since its bits shall be scrambled or lacking. An image file, for instance, 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, etc. In case this kind of an issue occurs and it's not found by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the data is synced between different drives, the corrupted file will be duplicated on all other drives and the harm will be long term. A number of widespread file systems either don't have real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a common problem on hosting servers where substantial volumes of data are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the information uploaded in each and every shared web hosting
account which is created on our cloud platform since we use the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption through a unique checksum for each file. We will store your data on multiple SSD drives which operate in a RAID, so the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all files on all 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 replaces that file with an undamaged copy from some other drive from the RAID. No other file system uses checksums, so it's possible for data to become silently corrupted and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your data.
