Data corruption is the damage of data caused by various software or hardware failures. Once a file gets damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, which makes it a significant problem for hosting servers as fails are more likely to happen on bigger hard disk drives where considerable volumes of information are kept. 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 bad file will be treated as a good one and it will be duplicated on all the drives, making the harm permanent. A lot of the file systems that run on web servers nowadays often cannot find corrupted files in real time or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your Internet sites in a shared hosting
account with our company, you won't need to worry about any of your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the advanced ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any info that you upload will be stored in a RAID i.e. simultaneously on many different SSD drives. All the file systems synchronize the files between the separate drives using such a setup, but there's no real warranty that a file won't be corrupted. This can happen throughout the writing process on any drive and afterwards a corrupted copy can be copied on all other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives immediately and if a corrupted file is found, it is replaced with a good copy with the correct checksum from another drive. In this way, your info will stay undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be shielded from silent data corruption because all our storage servers employ the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to guarantee the integrity of each and every file. When you upload content to your account, it will be kept on several redundant drives working in a RAID i.e. the files shall be the same across all drives. All the copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the copies in real time, so if it identifies a mismatch, that would indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, prolonging the time needed for the server to return online. ZFS is the sole file system that can really protect your content from silent data corruption.
