Data corruption is the damage of information because of various hardware or software failures. When a file gets corrupted, it will no longer function properly, so an app will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a significant problem for web hosting servers as fails are much more likely to occur on larger in size hard drives where substantial volumes of info are kept. If a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it is likely that the bad file will be treated as a standard one and will be duplicated on all drives, making the damage permanent. Lots of the file systems which run on web servers nowadays often cannot discover corrupted files in real time or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your Internet sites in a cloud hosting account with our firm, you will not have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All the data that you upload will be saved in a RAID i.e. simultaneously on a large number of SSDs. All the file systems synchronize the files between the separate drives with such a setup, but there is no real warranty that a file won't get corrupted. This may happen throughout the writing process on any drive and after that a bad copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all drives instantly and in case a corrupted file is identified, it's replaced with a good copy with the correct checksum from another drive. That way, your info will remain intact no matter what, even if a whole drive fails.
