Data corruption is the damage of information because of various software or hardware failures. When a file is damaged, it will no longer work accurately, so an app will not start or will 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 information getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for hosting servers as fails are very likely to occur on larger hard disks where large volumes of info are located. When a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it's likely that the damaged file will be treated as a standard one and it'll be duplicated on all of the drives, making the damage permanent. A lot of the file systems that run on web servers today often are not able to locate corrupted files in real time or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the data uploaded in each and every shared hosting
account which is made on our cloud platform since we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption through a unique checksum for every single file. We will store your data on a number of SSD drives that work in a RAID, so exactly the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with an undamaged copy from a different drive from the RAID. No other file system uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server using ZFS, you don't 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 in case you get one of our semi-dedicated server
plans due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums to make sure that all the files are intact at all times. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Due to the fact that we store all content on multiple drives simultaneously, 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 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 right away, avoiding any probability of the damaged copy to be synchronized on the rest of the hard disks. ZFS is the only file system you can get that uses checksums, which makes it far superior to other file systems which cannot identify silent data corruption and copy bad files across drives.
