Data corruption is the damage of data caused by various software or hardware failures. When a file is damaged, it will no longer function properly, so an app will not start or will give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, that makes it a serious problem for web hosting servers as failures are more likely to occur on larger hard disk drives where significant volumes of info are located. If a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a standard one and it will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that run on web servers nowadays often cannot locate corrupted files in real time or they need time-consuming system checks during which the server isn't functioning.
No Data Corruption & Data Integrity in Web Hosting
In case you host your sites in a web hosting
account from our firm, you do not need to worry about any of your data ever getting damaged. We can guarantee that since our cloud hosting platform uses the reliable ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be kept in a RAID i.e. simultaneously on many different SSD drives. A lot of file systems synchronize the files between the separate drives using such a setup, but there is no real guarantee that a file will not get corrupted. This could occur throughout the writing process on each drive and after that a corrupted copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives instantly and in the event that a corrupted file is found, it's swapped with a good copy with the correct checksum from some other drive. By doing this, your info will remain undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be resistant to silent data corruption since all of our storage servers employ the reliable ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to verify the integrity of each file. When you upload content to your account, it will be placed on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all drives. All the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, so if it identifies a mismatch, that will 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 won't become corrupted and there will not be any need for a time-consuming system check that other file systems perform after some malfunction, prolonging the time needed for the server to go back online. ZFS is the only file system that can truly protect your content from silent data corruption.
