Data corruption is the damage of info caused by various software or hardware problems. The moment a file is corrupted, it will no longer work accurately, so an app will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for web hosting servers as failures are much more likely to happen on larger hard disk drives where large volumes of info are kept. In case a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as an ordinary one and will be duplicated on all the drives, making the damage permanent. A lot of the file systems that operate on web servers today often cannot discover corrupted files in real time or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the info uploaded in every shared web hosting account which is created on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption via a unique checksum for every single file. We'll store your information on multiple SSD drives that operate in a RAID, so exactly the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all files on all the 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 an undamaged copy from another drive from the RAID. No other file system uses checksums, so it is possible for data to become silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you don't have to worry about the integrity of your info.
