Data corruption is the damage of data due to various hardware or software fails. The moment a file is damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, that makes it a significant problem for website hosting servers as fails are more likely to occur 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's likely that the bad file will be treated as an undamaged one and it'll be copied on all the drives, making the damage permanent. A huge number of the file systems that operate on web servers these days often are unable to recognize corrupted files instantly or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the information uploaded in every shared hosting account that is created on our cloud platform since we employ 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'll store your data on multiple NVMe drives that operate in a RAID, so the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all of the files on all 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 swaps that file with an undamaged copy from some other drive from the RAID. There's no other file system that uses checksums, so it's easy for data to get silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be shielded from silent data corruption since all our storage servers employ the reliable ZFS file system. What makes the aforementioned 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 placed on several redundant drives employed in a RAID i.e. the files shall be the same across all disks. All of the copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, so if it detects a mismatch, that 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 is a sudden power failure, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check that other file systems perform after some breakdown, 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.
