The process of files getting corrupted resulting from some hardware or software failure is referred to as data corruption and this is one of the main problems that web hosting companies face because the larger a hard disk drive is and the more info is kept on it, the much more likely it is for data to get corrupted. You'll find different fail-safes, yet often the info gets corrupted silently, so neither the particular file system, nor the admins see anything. Thus, a damaged file will be handled as a good one and if the HDD is part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in reality the damage will be even worse. When a given file gets corrupted, it will be partly or entirely unreadable, which means that a text file will not be readable, an image file will present a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most well-known server file systems include various checks, they are likely to fail to identify some problem early enough or require an extensive period of time to be able to check all of the files and the web hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your Internet sites in a cloud website hosting account with our firm, you won't need to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform uses the leading-edge ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each and every file. All data that you upload will be stored in a RAID i.e. simultaneously on many SSD drives. Many file systems synchronize the files between the different drives with this kind of a setup, but there is no real guarantee that a file will not be corrupted. This can occur at the time of the writing process on any drive and afterwards a corrupted copy may be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives immediately and if a corrupted file is discovered, it's swapped with a good copy with the correct checksum from some other drive. By doing this, your information will remain undamaged no matter what, even if a whole drive fails.
