Data corruption is the damage of information due to various hardware or software failures. The moment a file is damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, which makes it a serious problem for web hosting servers as problems are more likely to occur on larger hard disks where substantial volumes of info are placed. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as an undamaged one and it will be duplicated on all the drives, making the damage permanent. A huge number of the file systems that operate on web servers today often are not able to recognize corrupted files in real time or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
We warrant the integrity of the info uploaded in each cloud web hosting
account which is created on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption thanks to a unique checksum for every single file. We'll store your info on a large number of SSD drives that function in a RAID, so exactly the same files will exist on several places at the same time. ZFS checks the digital fingerprint of all of 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 swaps that file with a healthy copy from another drive within the RAID. There's no other file system that uses checksums, so it's easy for data to be silently corrupted and the bad file to be replicated on all drives with time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not encounter any silent data corruption issues should you buy one of our semi-dedicated hosting
plans as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to ensure that all files are intact all the time. A checksum is a unique digital fingerprint that is allotted to each and every file saved on a server. Because we store all content on a number of drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that 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 possibility of the bad copy to be synchronized on the rest of the hard disks. ZFS is the sole file system you can get which uses checksums, which makes it much more dependable than other file systems that are not able to identify silent data corruption and copy bad files across hard drives.
