Data corruption is the damage of info due to various software or hardware failures. After a file is damaged, it will no longer work accurately, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as fails are much more likely to happen on larger hard disks where considerable volumes of info are located. In case a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a good one and will be duplicated on all drives, making the harm permanent. Lots of the file systems which operate on web servers nowadays often cannot locate corrupted files in real time or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your Internet sites in a shared hosting account with our company, you will not have to worry about any of your data ever getting corrupted. We can guarantee that since our cloud hosting platform works with the state-of-the-art ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on a number of SSDs. A lot of file systems synchronize the files between the different drives using this kind of a setup, but there is no real warranty that a file won't be corrupted. This may occur at the time of the writing process on each drive and after that a bad copy may be copied on the rest of the drives. What is different on our platform is that ZFS examines the checksums of all files on all drives right away and when a corrupted file is found, it's swapped with a good copy with the correct checksum from another drive. This way, your info will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption as all of our storage servers use the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to verify the integrity of every single file. When you upload content to your account, it'll be stored on several redundant drives operating in a RAID i.e. the files will be the same across all disks. All of the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, and if it discovers a mismatch, which would indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other disks. Even if there's a sudden power failure, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, extending the time needed for the server to get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
