The process of files getting damaged caused by some hardware or software failure is referred to as data corruption and this is one of the main problems which hosting companies face as the larger a hard drive is and the more information is filed on it, the much more likely it is for data to become corrupted. There're several fail-safes, yet often the information is corrupted silently, so neither the file system, nor the administrators detect a thing. As a result, a corrupted file will be treated as a standard one and if the hard disk drive is a part of a RAID, that file will be copied on all other disk drives. In principle, this is done for redundancy, but in reality the damage will be worse. When a given file gets corrupted, it will be partly or completely unreadable, therefore a text file will no longer be readable, an image file will show a random mix 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 frequently used server file systems include various checks, they are likely to fail to find some problem early enough or require an extensive amount of time in order to check all of the files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Website Hosting
If you host your sites in a website hosting account with our company, you won't need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any info that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. All file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file won't be corrupted. This can happen throughout the writing process on each drive and afterwards a corrupted copy can be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all drives live and if a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. This way, your information will stay undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not experience any kind of silent data corruption issues in case you purchase one of our semi-dedicated hosting solutions since the ZFS file system that we use on our cloud hosting platform uses checksums to make sure that all of your files are intact all of the time. A checksum is a unique digital fingerprint that is assigned 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 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 other hard drives. ZFS is the only file system you can get which uses checksums, which makes it far superior to other file systems that are not able to detect silent data corruption and duplicate bad files across drives.
