Data corruption is the damage of info due to various hardware or software problems. After a file gets corrupted, it will no longer function as it should, so an app will not start or will give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as failures are very likely to happen on larger hard disk drives where significant volumes of info are located. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as a regular one and it'll be duplicated on all drives, making the harm permanent. A huge number of the file systems that operate on web servers these days often are not able to identify corrupted files right away or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the info uploaded in each and every cloud hosting
account that is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption thanks to a unique checksum for every single file. We shall store your information on a large number of SSD drives that function in a RAID, so exactly the same files will be present on several places at once. ZFS checks the digital fingerprint of all files on all 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 inside the RAID. There's no other file system which uses checksums, so it's possible for data to get silently damaged and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any possibility of files getting damaged silently since the servers where your semi-dedicated server
account will be created use a powerful file system called ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we store all content on numerous 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 saved. In the event that there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and considering that this happens in real time, there is no chance that a damaged copy could remain on our hosting servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems include this type of checks and what's more, even during a file system check following an unexpected power loss, none of them can find silently corrupted files. In contrast, ZFS does not crash after a power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
