The process of files getting corrupted resulting from some hardware or software failure is called data corruption and this is one of the main problems which web hosting companies face as the larger a hard drive is and the more info is filed on it, the much more likely it is for data to get corrupted. You can find a couple of fail-safes, still often the info is damaged silently, so neither the particular file system, nor the admins see a thing. Thus, a bad file will be treated as a standard one and if the HDD is part of a RAID, that particular file will be copied on all other drives. In principle, this is done for redundancy, but in reality the damage will get worse. Once some file gets damaged, it will be partly or fully unreadable, therefore a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most frequently used server file systems have various checks, they frequently fail to discover some problem early enough or require an extensive time period to check all of the files and the server will not be functional for the time being.
No Data Corruption & Data Integrity in Hosting
We warrant the integrity of the info uploaded in any hosting account that is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We'll store your information on a number of NVMe drives that work in a RAID, so the exact same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy copy from another drive inside the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be protected against silent data corruption as all of our storage servers use the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it'll be placed on a couple of redundant drives in a RAID i.e. the files shall be the same on all disk drives. All copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, and if it finds a mismatch, which would indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other drives. Even if there is a sudden blackout, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some failure, prolonging the time needed for the server to return online. ZFS is the file system that can really protect your content from silent data corruption.
