Data corruption is the damage of info caused by various hardware or software problems. After a file is damaged, it will no longer work as it should, so an app will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and 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 website hosting servers as failures are very likely to occur on larger in size hard disks where vast 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 standard one and it'll be duplicated on all of the drives, making the harm permanent. Lots of the file systems that operate on web servers nowadays often are unable to find corrupted files immediately or they need time-consuming system checks through which the server isn't working.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the information uploaded in every shared web hosting
account which is created on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption using a unique checksum for every single file. We will store your information on multiple SSD drives that work in a RAID, so the very same files will be present 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 is different from what it needs to be, the file system swaps that file with a healthy version from another drive from the RAID. No other file system uses checksums, so it's easy for data to be silently corrupted and the bad file to be reproduced 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 data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not experience any silent data corruption issues whatsoever should you buy one of our semi-dedicated hosting
solutions as the ZFS file system that we work with on our cloud hosting platform uses checksums in order to ensure that all files are intact at all times. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Because we store all content on a number of drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any probability of the bad copy to be synchronized on the other hard disks. ZFS is the sole file system you will find which uses checksums, which makes it much more reliable than other file systems that are not able to detect silent data corruption and duplicate bad files across drives.
