Data corruption is the damage of information caused by various software or hardware fails. Once a file gets damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, which makes it a significant problem for hosting servers as fails are very likely to occur on larger in size hard drives where vast volumes of info are placed. When a drive is a part of a RAID and the data 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 will be duplicated on all drives, making the damage permanent. Lots of the file systems which run on web servers these days often are unable to find corrupted files instantly or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your Internet sites in a cloud web hosting account from our company, you will not have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform works with the leading-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All of the information that you upload will be stored in a RAID i.e. simultaneously on a large number of SSDs. All the file systems synchronize the files between the separate drives using this type of a setup, but there's no real warranty that a file will not be corrupted. This can occur during the writing process on each drive and after that a damaged copy can be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives right away and in case a corrupted file is located, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your info will remain unharmed no matter what, even if an entire drive fails.
