Data corruption is the damage of info because of various hardware or software fails. When a file is corrupted, it will no longer function correctly, so an app will not start or will give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an administrator, that makes it a serious problem for hosting servers as failures are much more likely to occur on larger hard drives where vast volumes of info are located. In case a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's likely that the bad file will be treated as an ordinary one and it'll be copied on all of the drives, making the harm permanent. A huge number of the file systems that run on web servers today often cannot recognize corrupted files immediately 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 data uploaded in any shared hosting
account which is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption using a unique checksum for each and every file. We shall store your info on multiple SSD drives that work in a RAID, so the very same files will be accessible 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 replaces that file with an undamaged version from some other drive inside the RAID. There's no other file system that uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be resistant to silent data corruption since all our storage servers work with the state-of-the-art ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be stored on several redundant drives being employed in a RAID i.e. the files shall be the same on all disks. All the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, and if it discovers a mismatch, which will indicate that one of the copies is damaged, it'll substitute that file with a healthy copy from one of the other disks. Even if there's a sudden power failure, the data on the servers won't get corrupted and there won't 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 get back online. ZFS is the file system that can really protect your content from silent data corruption.
