Data corruption is the damage of information due to various software or hardware fails. The moment a file gets corrupted, it will no longer function as it should, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for web hosting servers as problems are very likely to happen on larger in size hard drives where significant volumes of information are kept. In case a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as a standard one and it will be copied on all of the drives, making the harm permanent. A huge number of the file systems that run on web servers these days often cannot find 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 Shared Hosting

In case you host your sites in a shared hosting account from our company, you won't need to worry about your data ever getting corrupted. We can guarantee that because our cloud hosting platform uses the leading-edge ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be kept in a RAID i.e. simultaneously on many different SSDs. A lot of file systems synchronize the files between the different drives with such a setup, but there's no real guarantee that a file won't be corrupted. This can happen at the time of the writing process on each drive and then a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives live and when a corrupted file is identified, it is swapped with a good copy with the correct checksum from another drive. By doing this, your info will remain unharmed 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 shielded from silent data corruption since all our storage servers employ the effective ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of every single file. When you upload content to your account, it will be placed on several redundant drives operating in a RAID i.e. the files will be the same on all disk drives. All of the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, and if it finds a mismatch, that will indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other disks. Even if there is an unexpected power failure, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check that other file systems perform after some breakdown, 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.
