Data corruption is the damage of data caused by various hardware or software problems. When a file gets corrupted, it will no longer function correctly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for website hosting servers as problems are much more likely to happen on larger hard disk drives where significant volumes of info are placed. If a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as a standard one and it'll be duplicated on all of the drives, making the damage permanent. A huge number of the file systems which operate on web servers today often are unable to identify corrupted files right away or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the information uploaded in each web hosting account which is created on our cloud platform since we use the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption using a unique checksum for every single file. We'll store your info on a large number of SSD drives that function in a RAID, so exactly the same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with a healthy copy from another drive from the RAID. No other file system uses checksums, so it's easy for data to be silently damaged and the bad file to be replicated on all drives with time, but since this can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption because all our storage servers work with the effective ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to guarantee the integrity of every single file. When you upload content to your account, it will be saved on several redundant drives operating in a RAID i.e. the files shall be the same across all drives. All of the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, so if it registers a mismatch, which will indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other disks. Even if there is an unforeseen power loss, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check which 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 truly protect your content from silent data corruption.
