The process of files getting damaged as a result of some hardware or software failure is called data corruption and this is one of the main problems that hosting companies face because the larger a hard disk is and the more data is filed on it, the much more likely it is for data to become corrupted. You will find several fail-safes, but often the info is damaged silently, so neither the particular file system, nor the admins notice anything. Because of this, a corrupted file will be treated as a good one and if the HDD is a part of a RAID, that file will be copied on all other drives. In theory, this is for redundancy, but in reality the damage will be worse. The moment a file gets corrupted, it will be partially or fully unreadable, so a text file will not be readable, an image file will present a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most popular server file systems include various checks, they are likely to fail to find a problem early enough or require a long period of time to check all the files and the server will not be functional in the meantime.
No Data Corruption & Data Integrity in Website Hosting
If you host your websites in a website hosting account with our company, you don't have to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform uses the amazing ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. All of the info that you upload will be stored in a RAID i.e. simultaneously on a large number of SSD drives. All the file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file won't get corrupted. This can happen during the writing process on any drive and after that a bad copy can be copied on the rest of the drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives instantly and when a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. This way, your information will continue to be intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't have to deal with any kind of silent data corruption issues if you get one of our semi-dedicated hosting plans because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all of the files are undamaged all of the time. A checksum is a unique digital fingerprint that is given to each and every file saved on a server. Because we store all content on multiple drives simultaneously, the same file uses the same checksum on all 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 should be, it replaces that file with a healthy copy without delay, avoiding any probability of the corrupted copy to be synchronized on the rest of the drives. ZFS is the sole file system on the market that uses checksums, which makes it far superior to other file systems which are not able to identify silent data corruption and copy bad files across drives.
