Data corruption is the damage of data because of various software or hardware problems. The moment a file is corrupted, it will no longer function as it should, so an application will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for hosting servers as fails are very likely to occur on larger in size hard drives where significant volumes of information are located. When a drive is 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 healthy one and it will be copied on all the drives, making the damage permanent. A huge number of the file systems that run on web servers nowadays often cannot detect corrupted files immediately or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Website Hosting

We warrant the integrity of the data uploaded in each and every website hosting account that is generated on our cloud platform as we work with the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each file. We shall store your information on multiple NVMe drives that work in a RAID, so the very same files will be present on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and in case the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from another drive within the RAID. There's no other file system which uses checksums, so it is easy for data to get silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your data.
