The process of files being corrupted as a result of some hardware or software failure is referred to as data corruption and this is among the main problems which web hosting companies face because the larger a hard disk is and the more data is kept on it, the much more likely it is for data to become corrupted. There are different fail-safes, but often the information gets damaged silently, so neither the particular file system, nor the administrators detect a thing. As a result, a corrupted file will be treated as a regular one and if the HDD is part of a RAID, the file will be copied on all other drives. Theoretically, this is for redundancy, but in reality the damage will be even worse. Once a given file gets corrupted, it will be partly or fully unreadable, so a text file will not be readable, an image file will display a random combination of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your site content. Although the most commonly used server file systems have various checks, they quite often fail to identify a problem early enough or require a long time period in order to check all of the files and the web hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Hosting
If you host your Internet sites in a shared hosting
account with our company, you won't need to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform works with the leading-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. All of the information that you upload will be stored in a RAID i.e. simultaneously on a large number of SSD drives. All of the file systems synchronize the files between the separate drives with such a setup, but there is no real guarantee that a file won't be corrupted. This can occur throughout the writing process on each drive and after that a corrupted copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all the drives live and if a corrupted file is discovered, it is swapped with a good copy with the correct checksum from another drive. By doing this, 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've avoided any possibility of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting
account will be created work with a powerful file system called ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we save all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. In case there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because this happens in real time, there's no chance that a corrupted copy can remain on our website hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems work with this kind of checks and in addition, even during a file system check following an unexpected blackout, none of them can detect silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
