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 drive is and the more information is stored on it, the more likely it is for data to be corrupted. You will find various fail-safes, yet often the data gets damaged silently, so neither the particular file system, nor the admins notice a thing. Because of this, a damaged file will be treated as a good one and if the hard disk drive is part of a RAID, that file will be copied on all other disk drives. In principle, this is done for redundancy, but in practice the damage will get worse. Once some file gets damaged, it will be partially or completely unreadable, which means that a text file will not be readable, an image file will display a random mix of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most commonly used server file systems have various checks, they are likely to fail to discover some problem early enough or require a vast amount of time to be able to check all the files and the server will not be operational for the time being.

No Data Corruption & Data Integrity in Hosting

In case you host your websites in a hosting account with our company, you will not need to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for every single file. All information that you upload will be kept in a RAID i.e. simultaneously on many different SSD drives. All the file systems synchronize the files between the separate drives using this type of a setup, but there's no real warranty that a file won't get corrupted. This could happen at the time of the writing process on each drive and then a corrupted copy can be copied on the other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all drives immediately and when a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. That way, your info will continue to be intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't experience any kind of silent data corruption issues if you acquire one of our semi-dedicated server plans since the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all of your files are undamaged at all times. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. Because we store all content on multiple 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. In the event that 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 possibility of the damaged copy to be synchronized on the remaining hard disks. ZFS is the only file system out there which uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and duplicate bad files across drives.
