The process of files being damaged owing to some hardware or software failure is referred to as data corruption and this is among the main problems which Internet hosting companies face as the larger a hard disk is and the more information is placed on it, the much more likely it is for data to become corrupted. There are a couple of fail-safes, yet often the data is damaged silently, so neither the particular file system, nor the admins notice a thing. Consequently, a corrupted file will be handled as a good one and if the HDD is part of a RAID, that file will be duplicated on all other disk drives. In theory, this is for redundancy, but in practice the damage will get even worse. The moment a file gets corrupted, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will present a random blend of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your content. Although the most widespread server file systems have various checks, they frequently fail to detect a problem early enough or require a long amount of time to be able to check all the files and the web hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Hosting
If you host your websites in a shared hosting account from our company, you won't have to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the amazing ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. All of the data that you upload will be saved in a RAID i.e. simultaneously on numerous NVMes. All of the file systems synchronize the files between the separate drives using this type of a setup, but there is no real guarantee that a file won't be corrupted. This can happen at the time of the writing process on any drive and after that a bad copy may be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives live and when a corrupted file is located, it's substituted with a good copy with the correct checksum from some other drive. That way, your info will stay unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be protected against silent data corruption as all our storage servers work with the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of each and every file. When you upload content to your account, it'll be kept on several redundant drives being employed in a RAID i.e. the files will be the same across all drives. All copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so if it registers a mismatch, that would indicate that one of the copies is corrupted, it will swap that file with a healthy copy from one of the other disks. Even if there is an unforeseen blackout, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check which other file systems perform after some failure, lengthening the time needed for the server to return online. ZFS is the sole file system that can truly protect your content from silent data corruption.
