Data corruption is the damage of data because of various hardware or software problems. When a file is corrupted, it will no longer function properly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open 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 web hosting servers as problems are more likely to happen on larger hard disks where substantial volumes of info are kept. When a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as an undamaged one and will be copied on all of the drives, making the damage permanent. A lot of the file systems which run on web servers today often cannot discover corrupted files right away or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Website Hosting
We guarantee the integrity of the data uploaded in every website hosting
account that is made on our cloud platform because we use the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption through a unique checksum for each and every file. We shall store your data on a large number of SSD drives that function in a RAID, so the very same files will be available on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with a healthy version from some other drive from the RAID. There's no other file system which uses checksums, so it's easy for data to get silently corrupted and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't need to deal with any kind of silent data corruption issues if you get one of our semi-dedicated server
packages as the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all files are undamaged all the time. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. Due to the fact that we store all content on a number of drives simultaneously, the same file uses the same checksum on all of 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 chance of the damaged copy to be synchronized on the remaining hard drives. ZFS is the only file system you will find that uses checksums, which makes it much more dependable than other file systems which are unable to detect silent data corruption and copy bad files across drives.
