Data corruption is the damage of info because of various hardware or software fails. When a file gets corrupted, it will no longer work as it should, so an app 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, which makes it a serious problem for hosting servers as problems are more likely to happen on larger in size hard disk drives where considerable volumes of information are located. When a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all of the drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often are unable to detect corrupted files right away or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your sites in a cloud website hosting account from our company, you don't need to worry about any of your data ever getting corrupted. We can ensure that since our cloud hosting platform uses the cutting-edge ZFS file system. The latter 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 saved in a RAID i.e. simultaneously on many SSD drives. Many file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file won't get corrupted. This could happen throughout the writing process on any drive and after that a bad copy may be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives instantly and in the event that a corrupted file is located, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your data will continue to be intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be resistant to silent data corruption since all of our storage servers employ the advanced ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be saved on several redundant drives operating in a RAID i.e. the files will be the same across all disks. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, and if it registers a mismatch, which would indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other drives. Even if there is an unexpected power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, extending the time needed for the server to get back online. ZFS is the file system that can truly protect your content from silent data corruption.
