The process of files being damaged due to some hardware or software failure is known as data corruption and this is among the main problems which Internet hosting companies face as the larger a hard drive is and the more information is kept on it, the much more likely it is for data to become corrupted. You can find several fail-safes, yet often the data becomes damaged silently, so neither the particular file system, nor the admins notice a thing. Thus, a bad file will be handled as a good one and if the hard disk drive is a part of a RAID, that particular file will be duplicated on all other drives. In theory, this is for redundancy, but in practice the damage will be worse. The moment a file gets corrupted, it will be partially or completely unreadable, therefore a text file will not be readable, an image file will show a random blend of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your site content. Although the most commonly used server file systems include various checks, they frequently fail to discover some problem early enough or require a vast amount of time to be able to check all files and the server will not be functional in the meantime.
No Data Corruption & Data Integrity in Cloud Hosting
If you host your Internet sites in a cloud hosting account with our firm, you do not have to worry about your data ever getting damaged. We can guarantee that since our cloud hosting platform works with the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All of the info that you upload will be saved in a RAID i.e. simultaneously on numerous SSDs. All of the file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file won't get corrupted. This could occur during the writing process on any drive and after that a bad copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives right away and in case a corrupted file is discovered, it's swapped with a good copy with the correct checksum from another drive. By doing this, your data will remain undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't need to deal with any silent data corruption issues whatsoever in case you acquire one of our semi-dedicated server plans due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all of the files are undamaged at all times. 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 at the same time, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. 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 right away, avoiding any chance of the damaged copy to be synchronized on the remaining hard drives. ZFS is the only file system you will find which uses checksums, which makes it much more dependable than other file systems that cannot detect silent data corruption and copy bad files across hard drives.
