Data corruption is the damage of info because of various hardware or software fails. After a file is corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, that makes it a serious problem for website hosting servers as fails are more likely to happen on larger hard disk drives where substantial volumes of information are placed. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it is likely that the bad file will be treated as a good one and will be copied on all of the drives, making the harm permanent. A lot of the file systems which run on web servers nowadays often cannot identify corrupted files in real time or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the information uploaded in every shared hosting
account that is created on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption thanks to a unique checksum for every single file. We shall store your data on a number of SSD drives that work in a RAID, so the very same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file differs from what it should be, the file system replaces that file with a healthy version from a different drive in the RAID. No other file system uses checksums, so it is easy for data to get silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server using ZFS, you won't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be shielded from silent data corruption as all our storage servers work with the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to verify the integrity of each file. When you upload content to your account, it will be saved on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all disk drives. All the copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, so if it identifies a mismatch, that will indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other drives. Even if there is a sudden blackout, the data on the servers won't be 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 file system which can really protect your content from silent data corruption.
