Data corruption is the damage of info because of various software or hardware problems. Once a file is corrupted, it will no longer function as it should, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, that makes it a significant problem for website hosting servers as problems are much more likely to happen on bigger hard drives where significant volumes of info are stored. If a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it is likely that the damaged file will be treated as a regular one and it'll be duplicated on all the drives, making the harm permanent. A huge number of the file systems which run on web servers these days often are not able to detect corrupted files immediately or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
If 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 guarantee that because our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. All the info that you upload will be saved in a RAID i.e. simultaneously on a large number of SSDs. All file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file won't get corrupted. This may happen during the writing process on each drive and afterwards a bad copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all of the drives live and in the event that a corrupted file is identified, it's swapped with a good copy with the correct checksum from some other drive. This way, your info will remain undamaged no matter what, even if an entire drive fails.
