Data corruption is the damage of information due to various software or hardware problems. Once a file is damaged, it will no longer work properly, so an app will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for hosting servers as problems are very likely to occur on bigger hard drives where substantial volumes of information are kept. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is likely that the bad file will be treated as a good one and it'll be duplicated on all the drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often are unable to discover corrupted files in real time or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account shall be guaranteed by the ZFS file system which we make use of on our cloud platform. Most hosting providers, like our firm, use multiple hard disk drives to store content and considering that the drives work in a RAID, exactly the same info is synchronized between the drives all the time. In case a file on a drive becomes corrupted for reasons unknown, yet, it's likely that it will be copied on the other drives as other file systems don't have special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy will be replaced with a good one from another hard drive. Because this happens instantly, there's no risk for any of your files to ever be corrupted.
