Data corruption is the damage of info due to various hardware or software fails. After a file is damaged, it will no longer function as it should, so an app will not start or shall give errors, a text file will be partially or entirely unreadable, an archive file 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 admin, that makes it a significant problem for web hosting servers as fails are more likely to occur on larger hard drives where considerable volumes of information are kept. In case a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it's very likely that the bad file will be treated as an ordinary one and will be duplicated on all of the drives, making the harm permanent. A lot of the file systems that operate on web servers today often cannot locate corrupted files right away or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the info uploaded in each and every shared hosting
account that is created on our cloud platform as we work with the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption through a unique checksum for every single file. We'll store your information on a large number of SSD drives which operate in a RAID, so the exact same files will be accessible on several places at once. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy version from some other drive in the RAID. There's no other file system that uses checksums, so it's possible for data to be silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be resistant to silent data corruption because all of our storage servers work with the innovative ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to guarantee the integrity of each file. When you upload content to your account, it will be kept on several redundant drives working in a RAID i.e. the files will be the same across all drives. All the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it finds a mismatch, which will indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other drives. Even if there's an unforeseen blackout, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, lengthening the time needed for the server to return online. ZFS is the file system which can truly protect your content from silent data corruption.
