The process of files getting corrupted because of some hardware or software failure is referred to as data corruption and this is one of the main problems that web hosting companies face because the larger a hard drive is and the more info is placed on it, the much more likely it is for data to get corrupted. There're a couple of fail-safes, still often the info becomes corrupted silently, so neither the particular file system, nor the administrators see anything. Thus, a corrupted file will be handled as a standard one and if the hard disk drive is a part of a RAID, the file will be duplicated on all other drives. In principle, this is done for redundancy, but in reality the damage will be worse. When a file gets damaged, it will be partially or fully unreadable, which means that a text file will no longer be readable, an image file will present a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your content. Although the most popular server file systems include various checks, they frequently fail to detect a problem early enough or require a vast period of time to check all the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Website Hosting

In case you host your Internet sites in a website hosting account with our firm, you do not need to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform uses the amazing ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any kind of info that you upload will be saved in a RAID i.e. simultaneously on numerous SSD drives. All the file systems synchronize the files between the different drives using this kind of a setup, but there's no real guarantee that a file won't get corrupted. This could happen during the writing process on each drive and after that a corrupted copy may 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 of the drives immediately and when a corrupted file is located, it's replaced with a good copy with the correct checksum from another drive. That way, your information will continue to be undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting damaged silently because the servers where your semi-dedicated hosting account will be created employ a powerful file system named ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we keep all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. When there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that this happens in real time, there is no chance that a damaged copy can remain on our servers or that it could be copied to the other drives in the RAID. None of the other file systems use this kind of checks and what is more, even during a file system check following a sudden power loss, none of them can find silently corrupted files. In comparison, ZFS won't crash after a blackout and the continual checksum monitoring makes a time-consuming file system check obsolete.
