Data corruption is the damage of info because of various hardware or software failures. The moment a file is damaged, it will no longer function properly, so an app will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for web hosting servers as problems are more likely to happen on larger in size hard disks where vast volumes of info are located. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and it'll be duplicated on all the drives, making the harm permanent. A lot of the file systems that operate on web servers nowadays often are unable to recognize corrupted files in real time or they need time-consuming system checks through which the server is not functioning.
No Data Corruption & Data Integrity in Shared Website Hosting
We warrant the integrity of the information uploaded in each and every shared website hosting account which is created on our cloud platform because we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption through a unique checksum for each file. We will store your information on a number of NVMe drives which function in a RAID, so identical files will exist on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with a healthy copy from another drive from the RAID. No other file system uses checksums, so it's possible for data to get silently corrupted 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 worry about the integrity of your information.
