Data corruption is the damage of data due to various hardware or software fails. When a file is corrupted, it will no longer work properly, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive file 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 administrator, which makes it a significant problem for website hosting servers as problems are very likely to occur on bigger hard disks where substantial volumes of information are placed. When a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it's likely that the bad file will be treated as a healthy one and it'll be duplicated on all the drives, making the harm permanent. A huge number of the file systems that run on web servers nowadays often are unable to identify corrupted files instantly or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the information uploaded in every cloud hosting
account that is generated on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption using a unique checksum for each and every file. We shall store your info on a large number of SSD drives which function in a RAID, so the exact same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with a healthy copy from a different drive within the RAID. There's no other file system that uses checksums, so it is easy for data to be silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any chance of files getting damaged silently because the servers where your semi-dedicated hosting
account will be created use a powerful file system called ZFS. Its advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. Since we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. In case there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because it happens right away, there is no chance that a damaged copy can remain on our website hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems use such checks and furthermore, even during a file system check following a sudden blackout, none of them will detect silently corrupted files. In contrast, ZFS does not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
