The process of files getting damaged as a result of some hardware or software failure is known as data corruption and this is among the main problems which Internet hosting companies face since the larger a hard drive is and the more info is placed on it, the much more likely it is for data to become corrupted. You'll find several fail-safes, still often the info becomes damaged silently, so neither the file system, nor the admins see a thing. As a result, a bad file will be handled as a good one and if the hard disk drive is a part of a RAID, the file will be duplicated on all other drives. Theoretically, this is for redundancy, but in practice the damage will get even worse. The moment some file gets damaged, it will be partially or completely unreadable, which means that a text file will not be readable, an image file will show a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most widely used server file systems have various checks, they frequently fail to find a problem early enough or require a long period of time to be able to check all the files and the web hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Shared Hosting
If you host your Internet sites in a shared hosting
account with our firm, you do not need to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform employs the leading-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All the info that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. All the file systems synchronize the files between the separate drives with this kind of a setup, but there's no real warranty that a file won't get corrupted. This may happen during the writing process on any drive and after that a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all of the drives right away and in the event that a corrupted file is found, it's swapped with a good copy with the correct checksum from some other drive. This way, your info will stay undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any possibility of files getting damaged silently since the servers where your semi-dedicated server
account will be created take advantage of a powerful file system known as ZFS. Its advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we save all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. When there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens instantly, there is no chance that a damaged copy can remain on our web servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems use this type of checks and what is more, even during a file system check right after an unexpected blackout, none of them will identify silently corrupted files. In comparison, ZFS won't crash after a power loss and the continual checksum monitoring makes a lenghty file system check unnecessary.
