The process of files getting damaged as a consequence of some hardware or software failure is referred to as data corruption and this is among the main problems that Internet 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 get corrupted. There are a couple of fail-safes, yet often the information is corrupted silently, so neither the particular file system, nor the administrators notice a thing. Thus, a damaged file will be handled as a good one and if the HDD is a part of a RAID, that particular file will be duplicated on all other disk drives. In theory, this is done for redundancy, but in practice the damage will get worse. When a given file gets corrupted, it will be partly or entirely unreadable, which means that a text file will no longer be readable, an image file will display a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most widespread server file systems have various checks, they often fail to find some problem early enough or require a vast period of time to check all of the files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your Internet sites in a shared hosting account with our firm, you don't need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the amazing ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any information that you upload will be saved in a RAID i.e. simultaneously on a number of SSDs. All of the file systems synchronize the files between the different drives with such a setup, but there is no real warranty that a file will not get corrupted. This may happen at the time of the writing process on any drive and afterwards a corrupted copy can be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives immediately and in the event that a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. That way, your information will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't need to deal with any kind of silent data corruption issues if you purchase one of our semi-dedicated hosting solutions as the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all files are intact at all times. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. As we store all content on multiple drives simultaneously, 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 in real time. 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 corrupted copy to be synchronized on the rest of the drives. ZFS is the sole file system out there which uses checksums, which makes it much more reliable than other file systems that cannot identify silent data corruption and copy bad files across drives.
