The process of files getting corrupted caused by some hardware or software failure is known as data corruption and this is among the main problems which hosting companies face since the larger a hard disk drive is and the more data is stored on it, the more likely it is for data to be corrupted. There're several fail-safes, still often the information is damaged silently, so neither the file system, nor the admins see a thing. Thus, a bad file will be treated as a standard one and if the hard drive is a 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 be even worse. The moment a file gets damaged, it will be partly or entirely unreadable, so a text file will no longer be readable, an image file will display 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 often fail to detect a problem early enough or require an extensive period of time to be able to check all the files and the hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Web Hosting
We guarantee the integrity of the data uploaded in any cloud web hosting account which is created on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption through a unique checksum for each file. We'll store your data on a large number of SSD drives which work in a RAID, so exactly the 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 the event that the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from a different drive within 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 won't have to concern yourself with the integrity of your info.
