Data corruption is the damage of data due to various hardware or software failures. When a file is damaged, it will no longer work correctly, so an app will not start or will give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as problems are more likely to happen on bigger hard disk drives where vast volumes of info are placed. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as a good one and it will be duplicated on all the drives, making the harm permanent. Lots of the file systems that operate on web servers these days often are unable to identify corrupted files instantly or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

We've dealt with the problem of silent data corruption on all our cloud hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems because it is the only one in existence which checks all files in real time by using a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it'll be stored on several NVMe drives and regularly synchronized between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as corrupted, it is replaced instantly with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be copied on the remaining NVMes. ZFS requires lots of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple powerful servers working together. If you host your Internet sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption since all of our storage servers employ the advanced ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it'll be kept on several redundant drives in a RAID i.e. the files will be the same on all drives. All of the copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, and if it discovers a mismatch, that will indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other drives. Even if there's a sudden 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, lengthening the time needed for the server to get back online. ZFS is the file system which can truly protect your content from silent data corruption.
