Data corruption is the damage of information because of various hardware or software problems. After a file gets damaged, it will no longer function accurately, so an application will not start or will 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 information getting harmed without any identification by the system or an administrator, that makes it a significant problem for website hosting servers as fails are much more likely to occur on larger hard disks where considerable volumes of info are kept. If a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as a good one and will be copied on all the drives, making the damage permanent. Lots of the file systems that run on web servers nowadays often are unable to discover corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Website Hosting

If you host your websites in a cloud website hosting account with our company, you do not have to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform uses the advanced ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. All data that you upload will be saved in a RAID i.e. simultaneously on many SSD drives. All the file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file will not be corrupted. This could happen throughout the writing process on each drive and then a damaged copy may be copied on all other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives in real time and in case a corrupted file is found, it's substituted with a good copy with the correct checksum from some other drive. This way, your data will remain intact no matter what, even if an entire drive fails.
