Data corruption is the damage of information caused by various software or hardware failures. The moment a file is damaged, it will no longer function correctly, so an app will not start or will give errors, a text file could be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as problems are very likely to happen on larger in size hard disks where vast volumes of info are placed. If a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's likely that the damaged file will be treated as a standard one and will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that operate on web servers today often are not able to identify corrupted files right away or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data which you upload to your new cloud hosting account shall be guaranteed by the ZFS file system that we work with on our cloud platform. The majority of internet hosting providers, like our company, use multiple hard disk drives to keep content and since the drives work in a RAID, exactly the same info is synchronized between the drives all the time. When a file on a drive becomes corrupted for reasons unknown, however, it's very likely that it will be duplicated on the other drives since alternative file systems don't offer special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, and the damaged copy shall be replaced with a good one from a different hard disk. Due to the fact that this happens immediately, there's no risk for any of your files to ever get damaged.
