Data corruption is the damage of data because of various software or hardware failures. After a file gets damaged, it will no longer function properly, so an application will not start or shall give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for web hosting servers as problems are much more likely to happen on bigger hard disks where large volumes of information are placed. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a healthy one and will be copied on all the drives, making the harm permanent. A lot of the file systems which run on web servers nowadays often cannot detect corrupted files right away or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Website Hosting

We guarantee the integrity of the data uploaded in each and every cloud website hosting account which is created on our cloud platform since we employ the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption through a unique checksum for every single file. We will store your info on a number of SSD drives that operate in a RAID, so the very same files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from a different drive within the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your info.
