Data corruption is the damage of info because of various software or hardware problems. The moment a file is damaged, it will no longer work as it should, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, that makes it a significant problem for hosting servers as failures are more likely to happen on bigger hard drives where vast volumes of information are located. If a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a regular one and it'll be copied on all of the drives, making the damage permanent. A huge number of the file systems that operate on web servers nowadays often cannot find corrupted files right away or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

We warrant the integrity of the data uploaded in every single shared web hosting account that is generated on our cloud platform since we use the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption using a unique checksum for every single file. We will store your data on a large number of SSD drives that work in a RAID, so the exact same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in the event that the checksum of any file is different from what it should be, the file system replaces that file with a healthy copy from some other drive in the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server using ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created work with a powerful file system known as ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. Since we store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has stored. In case there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and considering that this happens right away, there is no chance that a corrupted copy could remain on our servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems work with this kind of checks and what is more, even during a file system check following a sudden blackout, none of them can find silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
