Data corruption is the damage of data due to various software or hardware fails. Once a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file could be partially or fully 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 admin, which makes it a significant problem for hosting servers as fails are much more likely to occur on larger in size hard disks where substantial volumes of information are kept. If a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a standard one and it'll be duplicated on all drives, making the harm permanent. Lots of the file systems which operate on web servers today often are not able to find corrupted files immediately or they need time-consuming system checks through which the server is not functioning.
No Data Corruption & Data Integrity in Cloud Web Hosting
We guarantee the integrity of the information uploaded in any cloud web hosting
account that is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption through a unique checksum for every single file. We shall store your information on multiple SSD drives which function in a RAID, so exactly the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from some other drive in the RAID. No other file system uses checksums, so it is easy for data to get silently corrupted 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 worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting damaged silently since the servers where your semi-dedicated hosting
account will be created use a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is 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 remaining drives and the one it has saved. When there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and because it happens in real time, there is no chance that a corrupted copy can remain on our web hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems work with this type of checks and in addition, even during a file system check following a sudden power loss, none of them can detect silently corrupted files. In contrast, ZFS does not crash after an electrical power failure and the regular checksum monitoring makes a lenghty file system check unneeded.
