Data corruption is the damage of data because of various hardware or software failures. The moment a file gets corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, that makes it a serious problem for web hosting servers as fails are much more likely to happen on larger in size hard disks where vast volumes of info are placed. If a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as a good one and will be copied on all the drives, making the harm permanent. Lots of the file systems that operate on web servers nowadays often are unable to identify corrupted files in real time or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account will be ensured by the ZFS file system that we take advantage of on our cloud platform. The majority of internet hosting providers, including our firm, use multiple hard disks to store content and considering that the drives work in a RAID, identical info is synchronized between the drives all of the time. If a file on a drive becomes damaged for reasons unknown, yet, it is very likely that it will be duplicated on the other drives as other file systems don't have special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the damaged copy will be swapped with a good one from a different hard disk. Due to the fact that this happens immediately, there is no risk for any of your files to ever be damaged.
