Data corruption is the damage of information because of various hardware or software problems. The moment a file is corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as problems are much more likely to happen on bigger hard disks where substantial volumes of information are stored. In case a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as an ordinary one and will be copied on all drives, making the harm permanent. Lots of the file systems which operate on web servers these days often cannot locate corrupted files in real time or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Web Hosting

We warrant the integrity of the information uploaded in each cloud web hosting account that is made on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We will store your data on a number of SSD drives that function in a RAID, so the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file differs from what it should be, the file system replaces that file with an undamaged version from another drive inside the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you do not have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any possibility of files getting corrupted silently because the servers where your semi-dedicated server account will be created take advantage of a powerful file system known as ZFS. Its advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. As we save all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. When there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since it happens in real time, there is no chance that a damaged copy could remain on our web servers or that it can be copied to the other hard drives in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check following a sudden blackout, none of them can find silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
