Data corruption is the damage of info caused by various software or hardware failures. After a file is damaged, it will no longer work accurately, so an application will not start or shall give errors, a text file will be partially or fully unreadable, an archive 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 administrator, that makes it a serious problem for website hosting servers as problems are much more likely to occur on larger in size hard disks where substantial volumes of information are placed. In case a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is likely that the bad file will be treated as a regular one and it'll be duplicated on all the drives, making the harm permanent. Lots of the file systems that operate on web servers nowadays often cannot discover corrupted files right away or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
We guarantee the integrity of the data uploaded in every cloud web hosting
account which is generated on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption via a unique checksum for each file. We will store your info on a large number of SSD drives that function in a RAID, so the very same files will be available 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 is different from what it has to be, the file system swaps that file with a healthy version from another drive from the RAID. There's no other file system that uses checksums, so it's easy for data to become silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you do not have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not experience any silent data corruption issues whatsoever should you obtain one of our semi-dedicated server
solutions since the ZFS file system that we use on our cloud hosting platform uses checksums to make sure that all files are intact at all times. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. As we store all content on multiple drives at the same time, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any probability of the corrupted copy to be synchronized on the other hard drives. ZFS is the sole file system on the market that uses checksums, which makes it far superior to other file systems that cannot detect silent data corruption and duplicate bad files across drives.
