Data corruption is the damage of data due to various software or hardware fails. When a file is damaged, it will no longer work accurately, so an app will not start or shall give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, which makes it a serious problem for hosting servers as failures are more likely to occur on larger in size hard disk drives where significant volumes of information are placed. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as an ordinary one and will be copied on all of the drives, making the harm permanent. A lot of the file systems that run on web servers today often cannot discover corrupted files in real time or they need time-consuming system checks through which the server isn't working.
No Data Corruption & Data Integrity in Web Hosting
We warrant the integrity of the info uploaded in every single web hosting account which is generated on our cloud platform since we employ the advanced ZFS file system. The aforementioned 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 info on multiple SSD drives that function in a RAID, so the very 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 needs to be, the file system replaces that file with a healthy version from a different drive within the RAID. There's no other file system that uses checksums, so it's possible for data to become silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting corrupted silently because the servers where your semi-dedicated server account will be created work with a powerful file system known as ZFS. Its key advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we save all content on a number of 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 saved. When there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and since this happens right away, there's no chance that a damaged copy can remain on our 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 what's more, even during a file system check after a sudden blackout, none of them can identify silently corrupted files. In contrast, ZFS does not crash after a power loss and the continual checksum monitoring makes a time-consuming file system check unnecessary.
