Data corruption is the damage of data due to various software or hardware fails. When a file gets damaged, it will no longer function properly, so an application will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a serious problem for website hosting servers as failures are very likely to happen on bigger hard disk drives where significant volumes of information are stored. When 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 damaged file will be treated as a regular one and it will be duplicated on all the drives, making the harm permanent. A huge number of the file systems which run on web servers today often are not able to recognize corrupted files in real time or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your websites in a cloud website hosting
account from our firm, you will not need to worry about your data ever getting damaged. We can guarantee that because our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any info that you upload will be saved in a RAID i.e. simultaneously on a large number of SSD drives. Many file systems synchronize the files between the separate drives using this type of a setup, but there is no real warranty that a file will not be corrupted. This may happen at the time of the writing process on each drive and then a bad copy may be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all drives in real time and if a corrupted file is identified, it's replaced with a good copy with the correct checksum from another drive. That way, your information will continue to be intact no matter what, even if an entire drive fails.
