Data corruption is the damage of info because of various hardware or software problems. Once a file is corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, which makes it a serious problem for hosting servers as fails are very likely to happen on larger hard disk drives where considerable volumes of info are stored. In case a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it is very likely that the bad file will be treated as a standard one and it will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that operate on web servers today often are not able to identify corrupted files instantly or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the information uploaded in every single shared web hosting account which is made on our cloud platform because we use the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We'll store your data on a number of SSD drives that work in a RAID, so identical files will be present on several places at once. ZFS checks the digital fingerprint of all files on all the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged copy from a different drive within the RAID. No other file system uses checksums, so it's possible for data to get silently corrupted and the bad file to be replicated on all drives with 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 Hosting
We've avoided any risk of files getting damaged silently since the servers where your semi-dedicated hosting account will be created take advantage of 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 that's checked in real time. As we save 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's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since it happens instantly, there is no chance that a damaged copy could remain on our web servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems include this type of checks and in addition, even during a file system check after a sudden blackout, none of them can discover silently corrupted files. In contrast, ZFS doesn't crash after a power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
