The process of files getting corrupted owing to some hardware or software failure is referred to as data corruption and this is among the main problems that Internet 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 will find a couple of fail-safes, but often the info gets damaged silently, so neither the file system, nor the administrators notice anything. Consequently, a corrupted file will be handled as a good one and if the hard disk is part of a RAID, that particular file will be duplicated on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will get even worse. The moment some file gets damaged, it will be partly or completely unreadable, therefore a text file will not be readable, an image file will display a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most popular server file systems have various checks, they frequently fail to detect a problem early enough or require a vast amount of time to be able to check all files and the hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
In case you host your sites in a cloud hosting account with our company, you won't need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform uses the outstanding ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on numerous SSDs. Many file systems synchronize the files between the separate drives using such a setup, but there is no real warranty that a file will not get corrupted. This may occur during the writing process on any drive and after that a damaged copy may be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives right away and in case a corrupted file is discovered, it's replaced with a good copy with the correct checksum from some other drive. That way, your data will remain unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be protected against silent data corruption since all of our storage servers employ the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to ensure the integrity of each and every file. When you upload content to your account, it will be stored on several redundant drives being employed in a RAID i.e. the files will be the same on all disks. All the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, and if it registers a mismatch, which will indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, prolonging the time needed for the server to get back online. ZFS is the only file system that can truly protect your content from silent data corruption.
