Data corruption is the damage of information due to various software or hardware problems. Once a file gets damaged, it will no longer function correctly, so an app will not start or will give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for hosting servers as fails are very likely to happen on larger hard drives where considerable volumes of info are located. If a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as an ordinary one and will be duplicated on all drives, making the damage permanent. A lot of the file systems that run on web servers these days often are unable to find corrupted files in real time or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the info uploaded in each and every shared hosting account which is created on our cloud platform because we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption using a unique checksum for each file. We will store your info on multiple NVMe drives that work in a RAID, so the very same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with an undamaged version from some other drive in 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 replicated on all drives over time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption because all our storage servers make use of 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 each file. When you upload content to your account, it'll be saved on a couple of redundant drives in a RAID i.e. the files will be the same on all disks. All copies of a particular file will have the same checksum on all 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 will replace that file with a healthy copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, lengthening the time needed for the server to get back online. ZFS is the file system that can truly protect your content from silent data corruption.
