Data corruption is the damage of info because of various hardware or software fails. After a file gets corrupted, it will no longer function accurately, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, that makes it a significant problem for web hosting servers as fails are much more likely to occur on bigger hard disks where significant volumes of info are stored. When a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as an undamaged one and will be duplicated on all drives, making the harm permanent. Lots of the file systems that run on web servers nowadays often are not able to detect corrupted files instantly or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account shall be ensured by the ZFS file system which we take advantage of on our cloud platform. The vast majority of web hosting suppliers, like our firm, use multiple hard drives to store content and since the drives work in a RAID, the exact same info is synchronized between the drives at all times. If a file on a drive becomes corrupted for reasons unknown, yet, it is likely that it will be copied on the other drives since alternative file systems do not include special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the damaged copy shall be swapped with a good one from another disk drive. As this happens right away, there's no possibility for any of your files to ever get damaged.
