Data corruption is the damage of information caused by various software or hardware problems. Once a file is damaged, it will no longer work correctly, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for hosting servers as fails are very likely to occur on larger hard drives where large volumes of info are placed. When a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the bad file will be treated as a healthy one and it will be copied on all of the drives, making the damage permanent. A lot of the file systems that run on web servers today often are unable to discover corrupted files right away or they need time-consuming system checks through which the server is not functioning.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the information uploaded in each and every cloud hosting
account that is made on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption thanks to a unique checksum for each and every file. We will store your info on a number of SSD drives which function in a RAID, so the same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all the 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 replaces that file with an undamaged copy from another drive within the RAID. There's no other file system that uses checksums, so it's easy 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 will not have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't encounter any kind of silent data corruption issues whatsoever in case you purchase one of our semi-dedicated server
plans due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to ensure that all the files are intact all the time. A checksum is a unique digital fingerprint that is allotted to each and every file saved on a server. Due to the fact that we store all content on multiple drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 possibility of the damaged copy to be synchronized on the rest of the drives. ZFS is the sole file system you will find that uses checksums, which makes it much more dependable than other file systems that are not able to detect silent data corruption and copy bad files across hard drives.
