Data corruption is the damage of information because of various software or hardware problems. When a file is corrupted, it will no longer work accurately, so an app will not start or shall give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as fails are more likely to occur on larger in size hard drives where considerable volumes of information are stored. When a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all drives, making the harm permanent. A huge number of the file systems that operate on web servers today often are not able to discover corrupted files instantly or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
In case you host your websites in a cloud web hosting
account with our company, you won't need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform employs the amazing ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be stored in a RAID i.e. simultaneously on a large number of SSDs. All of the file systems synchronize the files between the separate drives using this type of a setup, but there's no real guarantee that a file won't be corrupted. This could occur at the time of the writing process on any drive and then a damaged copy may be copied on the other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all drives right away and if a corrupted file is found, it is substituted with a good copy with the correct checksum from another drive. In this way, your data will stay undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you buy one of our semi-dedicated server
solutions, you won't have to worry about silent file corruption because we use ZFS - a high level file system that checks all files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no danger for any part of your content at any time. In comparison, alternative file systems carry out checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the rest of the drives as well and you could lose crucial info. Because this isn't the case with ZFS, we can warrant the integrity of each file you upload no matter what.
