Data corruption is the damage of information due to various hardware or software fails. When a file gets damaged, it will no longer function accurately, so an app will not start or shall give errors, a text file can be partially or entirely 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, which makes it a serious problem for web hosting servers as problems are very likely to happen on larger hard drives where large volumes of information are stored. If a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it will be duplicated on all the drives, making the damage permanent. A huge number of the file systems that run on web servers nowadays often are unable to detect corrupted files immediately or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your Internet sites in a shared website hosting account with our company, you do not have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. Any data that you upload will be kept 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 guarantee that a file won't be corrupted. This could happen at the time of the writing process on any drive and after that a bad copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives in real time and in case a corrupted file is discovered, it's swapped with a good copy with the correct checksum from another drive. That way, your info will continue to be 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 shielded from silent data corruption since all our storage servers work with the innovative ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to ensure the integrity of each and every 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 disks. All of the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, and if it registers a mismatch, which will indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other disks. Even if there's an unexpected power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, prolonging the time needed for the server to go back online. ZFS is the sole file system that can really protect your content from silent data corruption.
