Data corruption is the damage of information caused by various hardware or software fails. Once a file is damaged, it will no longer work accurately, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, which makes it a significant problem for web hosting servers as fails are much more likely to happen on larger in size hard disk drives where considerable volumes of info are kept. In case a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a healthy one and will be copied on all drives, making the damage permanent. A huge number of the file systems that run on web servers these days often cannot locate corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data that you upload to your new shared web hosting
account will be ensured by the ZFS file system which we make use of on our cloud platform. The vast majority of hosting providers, like our company, use multiple hard drives to keep content and because the drives work in a RAID, the exact same information is synchronized between the drives all the time. If a file on a drive becomes corrupted for some reason, however, it is very likely that it will be duplicated on the other drives since other file systems don't feature special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the damaged copy shall be swapped with a good one from a different hard disk. Because this happens in real time, there is no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not have to deal with any kind of silent data corruption issues should you obtain 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 to guarantee that all files are undamaged all the time. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. As we store all content on a number of drives at the same time, 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 case 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 hard drives. ZFS is the only file system you can get that uses checksums, which makes it far superior to other file systems that cannot identify silent data corruption and duplicate bad files across drives.
