Data corruption is the damage of data because of various software or hardware problems. After a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive 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 administrator, which makes it a serious problem for website hosting servers as failures are much more likely to happen on larger hard disks where vast 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 likely that the damaged file will be treated as a standard one and it will be copied on all of the drives, making the damage permanent. A huge number of the file systems which operate on web servers these days often are not able to locate corrupted files instantly or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Website Hosting

If you host your websites in a shared website hosting account from our firm, you will not have to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform works with the advanced ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the data that you upload will be saved in a RAID i.e. simultaneously on many different NVMe drives. All the file systems synchronize the files between the different drives with such a setup, but there is no real guarantee that a file will not get corrupted. This may happen throughout the writing process on any drive and afterwards a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all drives right away and when a corrupted file is identified, it is replaced with a good copy with the correct checksum from some other drive. In this way, your data will remain intact no matter what, even if an entire drive fails.
