Data corruption is the damage of info due to various software or hardware fails. Once a file gets damaged, it will no longer function properly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, which makes it a serious problem for hosting servers as problems are more likely to occur on larger in size hard drives where substantial volumes of information are kept. If a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as a good one and will be copied on all of the drives, making the harm permanent. A huge number of the file systems which run on web servers nowadays often cannot locate corrupted files right away or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Cloud Web Hosting
If you host your websites in a cloud web hosting
account from our firm, you won't have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform works with the outstanding ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. Any info that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. All file systems synchronize the files between the different drives with such a setup, but there's no real warranty that a file won't get corrupted. This can occur during the writing process on each drive and then a corrupted copy can be copied on the other drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all of the drives instantly and in the event that a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. This way, your information will remain unharmed no matter what, even if a whole drive fails.
