Data corruption is the damage of information caused by various software or hardware problems. The moment a file is corrupted, it will no longer work properly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, that makes it a serious problem for hosting servers as fails are more likely to occur on bigger hard disk drives where vast volumes of info are kept. When a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as an undamaged one and it will be duplicated on all of the drives, making the damage permanent. Lots of the file systems which run on web servers nowadays often are not able to locate corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the data uploaded in every shared hosting account which is made on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption thanks to a unique checksum for each and every file. We'll store your data on multiple SSD drives that work in a RAID, so the very same files will be present on several places at the same time. ZFS checks the digital fingerprint of all 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 swaps that file with a healthy copy from another drive inside the RAID. There's no other file system that 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 that can never happen on a server using ZFS, you do not have to worry about the integrity of your information.
