Data corruption is the damage of information due to various hardware or software failures. When a file is damaged, it will no longer work accurately, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, that makes it a serious problem for website hosting servers as failures are more likely to happen on bigger hard disk drives where considerable volumes of information are placed. In case a drive is a 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 standard one and will be copied on all drives, making the damage permanent. A huge number of the file systems that operate on web servers today often cannot detect corrupted files right away or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Web Hosting
We guarantee the integrity of the information uploaded in every single web hosting account which is generated on our cloud platform because we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption via a unique checksum for every single file. We shall store your info on a large number of SSD drives which work 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 the drives in real time and in case the checksum of any file differs from what it has to be, the file system replaces that file with an undamaged copy from a different drive inside the RAID. There's no other file system that uses checksums, so it's easy for data to get silently corrupted and the bad file to be reproduced 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 possibility of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we store all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. If there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since it happens in real time, there's no chance that a corrupted copy could remain on our web hosting servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems use this kind of checks and in addition, even during a file system check right after an unexpected power failure, none of them will discover silently corrupted files. In contrast, ZFS doesn't crash after a blackout and the continual checksum monitoring makes a time-consuming file system check obsolete.
