Data corruption is the damage of data due to various software or hardware failures. When a file gets corrupted, it will no longer function properly, so an app will not start or shall give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as failures are very likely to happen on larger in size hard disks where substantial volumes of info are stored. When a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it will be duplicated on all of the drives, making the damage permanent. A lot of the file systems that run on web servers these days often are unable to recognize corrupted files in real time or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Website Hosting

If you host your websites in a website hosting account with our firm, you do not need to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform employs the amazing ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any kind of information that you upload will be stored in a RAID i.e. simultaneously on a number of NVMes. A lot of file systems synchronize the files between the different drives with this kind of a setup, but there's no real warranty that a file won't get corrupted. This may occur throughout the writing process on each drive and after that a damaged copy may 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 of the drives immediately and when a corrupted file is identified, it is substituted with a good copy with the correct checksum from some other drive. In this way, your data will continue to be undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting damaged silently since the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we store all content on numerous NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has stored. In case there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens in real time, there's no chance that a corrupted copy could remain on our web hosting servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems employ this type of checks and in addition, even during a file system check after a sudden power failure, none of them can identify silently corrupted files. In comparison, ZFS will not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
