Data corruption is the damage of data due to various hardware or software fails. The moment a file gets damaged, it will no longer work accurately, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, which makes it a significant problem for web hosting servers as failures are very likely to happen on larger in size hard drives where vast volumes of information are located. If a drive is part of a RAID and the data on it is duplicated 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 the drives, making the harm permanent. Lots of the file systems that operate on web servers these days often are not able to recognize corrupted files immediately or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Hosting
The integrity of the data that you upload to your new hosting account shall be guaranteed by the ZFS file system that we make use of on our cloud platform. The vast majority of hosting providers, including our company, use multiple hard disk drives to keep content and considering that the drives work in a RAID, identical info is synchronized between the drives all the time. In case a file on a drive gets corrupted for some reason, however, it is very likely that it will be copied on the other drives because other file systems don't have special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy will be substituted with a good one from another hard disk drive. Because this happens instantly, there is no risk for any of your files to ever be damaged.
