Data corruption is the damage of information due to various software or hardware failures. The moment a file is corrupted, it will no longer function correctly, so an app 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 data getting damaged without any identification by the system or an admin, that makes it a significant problem for web hosting servers as problems are very likely to happen on larger hard disks where substantial volumes of information are kept. In case 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 bad file will be treated as a good one and will be copied on all of the drives, making the harm permanent. A lot of the file systems which run on web servers today often are unable to identify corrupted files immediately or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the info uploaded in every cloud hosting account which is generated on our cloud platform because we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption via a unique checksum for each file. We will store your info on a large number of SSD drives which work in a RAID, so the exact same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from a different drive within the RAID. There's no other file system that uses checksums, so it is easy for data to become silently damaged and the bad file to be replicated on all drives with time, but since this can never happen on a server using ZFS, you will not have to worry about the integrity of your data.
