Data corruption is the damage of info due to various hardware or software fails. The moment a file is corrupted, it will no longer work as it should, so an application will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, which makes it a serious problem for website hosting servers as failures are more likely to occur on bigger hard drives where large volumes of info are stored. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as a standard one and it'll be copied on all drives, making the damage permanent. Lots of the file systems which operate on web servers nowadays often are unable to find corrupted files immediately or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Hosting
We guarantee the integrity of the info uploaded in any hosting account which is generated on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each file. We will store your data on a large number of SSD drives which operate in a RAID, so the very same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all 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 version from some other drive in the RAID. There's no other file system that uses checksums, so it is easy for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your info.
