Data corruption is the damage of information because of various software or hardware fails. After a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file can be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a serious problem for website hosting servers as failures are very likely to occur on larger in size hard disks where considerable volumes of information are located. When 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 an undamaged one and it will be duplicated on all drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often are unable to recognize corrupted files right away or they need time-consuming system checks through which the server isn't working.
No Data Corruption & Data Integrity in Cloud Web Hosting
We warrant the integrity of the data uploaded in each and every cloud web hosting account that is created on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We shall store your information on multiple SSD drives which operate in a RAID, so the very same files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from some other drive inside the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be duplicated on all drives over time, but since this can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting corrupted silently since the servers where your semi-dedicated server account will be created use a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. Since we store all content on multiple 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 stored. When there's a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that it happens instantly, there is no chance that a damaged copy could remain on our web hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems include this type of checks and what's more, even during a file system check after a sudden electrical power failure, none of them can find silently corrupted files. In comparison, ZFS will not crash after a power loss and the constant checksum monitoring makes a lenghty file system check unneeded.
