The process of files getting damaged resulting from some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face since the larger a hard disk is and the more data is filed on it, the more likely it is for data to get corrupted. There're different fail-safes, but often the data becomes corrupted silently, so neither the file system, nor the administrators see anything. As a result, a damaged file will be handled as a good one and if the hard disk is part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will get worse. The moment a given file gets damaged, it will be partially or fully unreadable, so a text file will not be readable, an image file will present a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your content. Although the most commonly used server file systems include various checks, they often fail to detect a problem early enough or require a long period of time to check all files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Web Hosting
We guarantee the integrity of the information uploaded in each cloud web hosting
account that is generated on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption through a unique checksum for each and every file. We shall store your information on multiple SSD drives that work in a RAID, so the same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy copy from a different drive from the RAID. No other file system uses checksums, so it is easy for data to get silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not experience any silent data corruption issues should you obtain one of our semi-dedicated hosting
packages since the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all of your files are undamaged all of the time. A checksum is a unique digital fingerprint which is given to each and every file saved on a server. Since we store all content on a number of drives at the same time, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any chance of the damaged copy to be synchronized on the rest of the hard drives. ZFS is the sole file system you can get which uses checksums, which makes it much more dependable than other file systems which are not able to detect silent data corruption and duplicate bad files across hard drives.
