The process of files getting damaged caused by some hardware or software failure is called data corruption and this is one of the main problems which Internet hosting companies face since the larger a hard disk is and the more info is kept on it, the more likely it is for data to become corrupted. You can find various fail-safes, but often the info is damaged silently, so neither the file system, nor the admins notice a thing. Consequently, a corrupted file will be handled as a regular one and if the hard disk drive is a part of a RAID, that file will be duplicated on all other disk drives. In theory, this is for redundancy, but in reality the damage will be worse. The moment a given file gets damaged, it will be partly or fully unreadable, which means that a text file will not be readable, an image file will display a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your content. Although the most widespread server file systems feature various checks, they quite often fail to discover a problem early enough or require a long amount of time to be able to check all files and the web hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Cloud Hosting
If you host your sites in a cloud hosting
account with our company, you do not need to worry about your data ever getting corrupted. We can guarantee that as our cloud hosting platform works with the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All information that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. Many file systems synchronize the files between the different drives using this kind of a setup, but there's no real guarantee that a file won't get corrupted. This may happen during the writing process on any drive and afterwards a damaged copy can be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all drives immediately and in case a corrupted file is located, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your data will continue to be intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you acquire one of our semi-dedicated hosting
plans, you will not have to worry about silent data corruption because we use ZFS - a high level file system which keeps track of all files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between several SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no danger for any part of your content at any time. In contrast, other file systems carry out checks only after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy could be replicated on the other drives as well and you can lose precious info. Because this isn't the case with ZFS, we warrant the integrity of each and every file you upload no matter what.
