Data corruption is the damage of data because of various software or hardware failures. When a file is damaged, it will no longer work correctly, 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 unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as failures are much more likely to occur on bigger hard disks where large volumes of information are placed. When a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as a healthy one and will be copied on all drives, making the harm permanent. A huge number of the file systems that run on web servers nowadays often are not able to recognize corrupted files in real time or they need time-consuming system checks through which the server isn't working.
No Data Corruption & Data Integrity in Shared Website Hosting
We warrant the integrity of the information uploaded in every shared website hosting
account which 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 avoid silent data corruption thanks to a unique checksum for each file. We shall store your information on a number of SSD drives which operate in a RAID, so the exact same files will exist on several places at once. 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 differs from what it has to be, the file system swaps that file with a healthy version from a different drive inside the RAID. There's no other file system which uses checksums, so it's easy for data to become silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not encounter any kind of silent data corruption issues should you purchase one of our semi-dedicated hosting
solutions due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all of the files are intact at all times. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. As we store all content on multiple drives at the same time, the same file uses the same checksum on all 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 has to 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 disks. ZFS is the only file system available on the market that uses checksums, which makes it much more reliable than other file systems which are not able to detect silent data corruption and copy bad files across drives.
