Data corruption is the damage of data due to various software or hardware problems. When a file gets corrupted, it will no longer function as it should, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and 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 failures are very likely to occur on larger hard disks where substantial volumes of info are placed. If a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a healthy one and it'll be copied on all the drives, making the harm permanent. A huge number of the file systems which run on web servers today often cannot discover corrupted files immediately or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the information uploaded in every cloud website hosting
account that is made on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption via a unique checksum for every single file. We shall store your info on multiple SSD drives which work in a RAID, so identical files will be available on several places simultaneously. ZFS checks the digital fingerprint of all files on all drives in real time and in case the checksum of any file is different from what it has to be, the file system swaps that file with a healthy copy from some other drive from 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 this can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated server
account will be created work with a powerful file system named ZFS. Its key advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. As we keep all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. In the event that there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since it happens right away, there's no chance that a corrupted copy could remain on our web hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems use this type of checks and furthermore, even during a file system check following an unexpected electrical power failure, none of them will 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 unnecessary.
