Data corruption is the damage of info due to various hardware or software problems. The moment a file gets corrupted, it will no longer function properly, 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 and unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, which makes it a serious problem for web hosting servers as failures are very likely to occur on larger in size hard drives where substantial volumes of information are stored. If a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as an undamaged one and will be copied on all drives, making the damage permanent. A lot of the file systems that operate on web servers today often are not able to discover corrupted files immediately or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Cloud Web Hosting
We guarantee the integrity of the information uploaded in each cloud web hosting account that is made on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption using a unique checksum for every single file. We'll store your data on a large number of SSD drives that operate in a RAID, so identical files will exist on several places concurrently. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file differs from what it should be, the file system replaces that file with an undamaged version from some other drive in the RAID. No other file system uses checksums, so it is possible for data to get silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you won't have to worry about the integrity of your information.
