The process of files getting damaged due to some hardware or software failure is called data corruption and this is one of the main problems which web hosting companies face because the larger a hard drive is and the more data is placed on it, the much more likely it is for data to become corrupted. There are a couple of fail-safes, yet often the information gets corrupted silently, so neither the file system, nor the admins notice a thing. Because of this, a bad file will be treated as a regular one and if the hard disk drive is part of a RAID, that particular file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in practice the damage will be even worse. Once some file gets corrupted, it will be partially or fully unreadable, therefore a text file will no longer be readable, an image file will display a random blend of colors in case it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your site content. Although the most widely used server file systems feature various checks, they are likely to fail to find some problem early enough or require a long time period in order to check all the files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your websites in a shared website hosting account from our company, you will not need to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All information that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. Many file systems synchronize the files between the different drives with this kind of a setup, but there is no real guarantee that a file will not get corrupted. This can occur throughout the writing process on each drive and after that a damaged copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives in real time and in the event that a corrupted file is found, it is swapped with a good copy with the correct checksum from another drive. That way, your information will stay undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not experience any kind of silent data corruption issues whatsoever should you acquire one of our semi-dedicated server plans due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all the files are undamaged all the time. A checksum is a unique digital fingerprint which is given to each and every file saved on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. When 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 chance of the bad copy to be synchronized on the remaining hard disks. ZFS is the only file system available on the market which uses checksums, which makes it much more reliable than other file systems that cannot identify silent data corruption and duplicate bad files across hard drives.
