Data corruption is the damage of data because of various hardware or software fails. Once a file is corrupted, it will no longer function accurately, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as fails are more likely to occur on larger in size hard disks 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 standard one and will be duplicated on all the drives, making the harm permanent. A huge number of the file systems that operate on web servers today often are not able to find corrupted files right away or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

We guarantee the integrity of the info uploaded in each cloud website hosting account that is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent 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 same files will exist on several places at the same time. ZFS checks the digital fingerprint of all files on all the drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from a different drive within the RAID. No other file system uses checksums, so it's possible for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you won't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any chance of files getting damaged silently as the servers where your semi-dedicated server account will be created use a powerful file system known as ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. As we store 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. In case there's a mismatch, the bad copy is replaced with a good one from one of the other drives and since this happens in real time, there's no chance that a corrupted copy could remain on our website hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems use such checks and furthermore, even during a file system check following a sudden power loss, none of them can find silently corrupted files. In comparison, ZFS will not crash after a blackout and the regular checksum monitoring makes a time-consuming file system check obsolete.
