Data corruption is the damage of data because of various software or hardware problems. The moment a file is damaged, it will no longer function correctly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a serious problem for website hosting servers as failures are more likely to happen on bigger hard disks where large volumes of info are placed. When a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a good one and it will be duplicated on all of the drives, making the damage permanent. A huge number of the file systems that run on web servers these days often cannot identify corrupted files in real time or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Website Hosting

If you host your sites in a website hosting account with our company, you will not have to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the state-of-the-art ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be kept in a RAID i.e. simultaneously on a number of NVMes. All file systems synchronize the files between the different drives using such a setup, but there is no real guarantee that a file won't get corrupted. This could occur throughout the writing process on any drive and then a bad copy may be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives immediately and if a corrupted file is identified, it's swapped with a good copy with the correct checksum from some other drive. This way, your info will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system named 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. Since we keep all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. In case there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and considering that it happens right away, there is no chance that a corrupted copy could remain on our hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems work with this type of checks and what is more, even during a file system check after a sudden power loss, none of them can identify silently corrupted files. In comparison, ZFS doesn't crash after a blackout and the constant checksum monitoring makes a time-consuming file system check obsolete.
