The process of files being corrupted as a consequence of some hardware or software failure is called data corruption and this is one of the main problems that Internet hosting companies face since the larger a hard disk drive is and the more data is filed on it, the much more likely it is for data to be corrupted. You can find various fail-safes, but often the info becomes corrupted silently, so neither the particular file system, nor the administrators see anything. Thus, a damaged file will be handled as a good one and if the hard disk drive is a part of a RAID, that particular file will be copied on all other drives. In principle, this is for redundancy, but in practice the damage will be even worse. When some file gets damaged, it will be partially or entirely unreadable, so a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most widely used server file systems include various checks, they frequently fail to detect a problem early enough or require a long time period to check all the files and the hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Cloud Web Hosting
In case you host your websites in a cloud web hosting account from our firm, you don't need to worry about your data ever getting corrupted. We can guarantee that as our cloud hosting platform works with the cutting-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any info that you upload will be saved in a RAID i.e. simultaneously on numerous SSDs. All of the file systems synchronize the files between the separate drives using such a setup, but there is no real guarantee that a file won't get corrupted. This may happen throughout the writing process on any drive and then a corrupted copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all of the drives in real time and when a corrupted file is discovered, it's swapped with a good copy with the correct checksum from some other drive. That way, your information will stay intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you buy one of our semi-dedicated hosting packages, you will not need to worry about silent file corruption since we use ZFS - a high level file system which keeps track of all the files in real time. Every time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a number of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens immediately, so there will be no risk for any part of your content at any time. In comparison, all of the other file systems execute checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the rest of the drives as well and you can lose critical info. Because this is not the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
