Data corruption is the damage of info due to various hardware or software failures. When a file gets corrupted, it will no longer work correctly, so an application will not start or shall give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, that makes it a significant problem for website hosting servers as fails are much more likely to occur on larger in size hard drives where vast volumes of info are placed. In case a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as a good one and it'll be copied on all of the drives, making the harm permanent. A lot of the file systems that run on web servers these days often cannot locate corrupted files right away or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your Internet sites in a cloud hosting account with our company, you don't have to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform employs the amazing ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any info that you upload will be saved in a RAID i.e. simultaneously on multiple NVMes. All of the file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file won't get corrupted. This may occur during the writing process on each drive and after that a damaged copy can be copied on all other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all drives live and in the event that a corrupted file is found, it is replaced with a good copy with the correct checksum from some other drive. By doing this, your info will stay intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any kind of silent data corruption issues whatsoever in case you get one of our semi-dedicated server plans as the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all of your files are intact all the time. A checksum is a unique digital fingerprint which is given to each and every file saved on a server. Since 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 in real time. If 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 right away, avoiding any probability of the corrupted copy to be synchronized on the other hard disks. ZFS is the sole file system out there which uses checksums, which makes it far superior to other file systems that cannot detect silent data corruption and copy bad files across drives.
