The process of files being corrupted owing to some hardware or software failure is called data corruption and this is among the main problems which web hosting companies face because the larger a hard disk drive is and the more info is filed on it, the more likely it is for data to be corrupted. There're various fail-safes, but often the data becomes damaged silently, so neither the particular file system, nor the administrators detect a thing. Consequently, a damaged file will be handled as a regular one and if the hard drive is a part of a RAID, the file will be duplicated on all other drives. In principle, this is done for redundancy, but in practice the damage will get worse. The moment some file gets damaged, it will be partly or completely unreadable, which means that a text file will no longer be readable, an image file will display a random mix of colors if it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most widely used server file systems have various checks, they frequently fail to detect a problem early enough or require an extensive amount of time to be able to check all files and the web hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Web Hosting
In case you host your sites in a cloud web hosting
account from our company, you won't have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the amazing ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on a number of SSD drives. A lot of file systems synchronize the files between the different drives with such a setup, but there is no real warranty that a file won't be corrupted. This could occur throughout the writing process on each drive and then a bad copy may be copied on all other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all drives right away and if a corrupted file is discovered, it is swapped with a good copy with the correct checksum from another 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 Servers
You won't have to deal with any kind of silent data corruption issues whatsoever should you obtain one of our semi-dedicated server
plans because the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all of your files are intact all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. Due to the fact that we store all content on a number of drives at the same time, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. If it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any probability of the damaged copy to be synchronized on the rest of the hard disks. ZFS is the only file system you can find that uses checksums, which makes it much more reliable than other file systems which are not able to detect silent data corruption and duplicate bad files across drives.
