Data corruption is the damage of data because of various software or hardware failures. The moment a file gets damaged, it will no longer function properly, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as problems are much more likely to occur on larger in size hard disk drives where considerable volumes of info are located. In case a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's very likely that the bad file will be treated as a healthy one and it will be duplicated on all drives, making the harm permanent. Lots of the file systems which run on web servers these days often cannot recognize corrupted files in real time or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Hosting
We guarantee the integrity of the data uploaded in any hosting
account which is created on our cloud platform as we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each file. We'll store your information on a 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 of the files on all of the drives in real time and in case the checksum of any file is different from what it has to be, the file system replaces that file with a healthy copy from another drive inside the RAID. No other file system uses checksums, so it is easy for data to be silently corrupted and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not encounter any kind of silent data corruption issues whatsoever should you purchase one of our semi-dedicated server
solutions due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums to ensure that all of your files are intact all of the time. A checksum is a unique digital fingerprint which is assigned to each and every file kept 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. If 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 rest of the drives. ZFS is the only file system you can get which uses checksums, which makes it far superior to other file systems that are not able to identify silent data corruption and copy bad files across hard drives.
