Data corruption is the damage of info caused by various hardware or software problems. Once a file gets corrupted, it will no longer work accurately, so an application will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, which makes it a significant problem for web hosting servers as failures are much more likely to occur on larger in size hard disks where vast volumes of info are stored. When a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as a healthy one and will be duplicated on all the drives, making the damage permanent. Lots of the file systems that operate on web servers these days often cannot recognize corrupted files instantly or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Website Hosting
The integrity of the data that you upload to your new cloud website hosting account will be ensured by the ZFS file system that we employ on our cloud platform. Most web hosting providers, like our firm, use multiple hard drives to keep content and since the drives work in a RAID, the exact same info is synchronized between the drives at all times. When a file on a drive is damaged for some reason, however, it's likely that it will be copied on the other drives since other file systems don't include special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy will be substituted with a good one from another disk drive. Because this happens instantly, there's no risk for any of your files to ever get damaged.
