The process of files being corrupted resulting from some hardware or software failure is called data corruption and this is one of the main problems which hosting companies face since the larger a hard drive is and the more data is placed on it, the more likely it is for data to become corrupted. There are different fail-safes, yet often the information becomes damaged silently, so neither the particular file system, nor the administrators see anything. Thus, a bad file will be handled as a regular one and if the hard disk 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 reality the damage will be worse. The moment a file gets damaged, it will be partially or entirely unreadable, therefore a text file will no longer be readable, an image file will display a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most popular server file systems have various checks, they frequently fail to find some problem early enough or require a long amount of time in order to check all of the files and the hosting server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Hosting

If you host your Internet sites in a shared hosting account from our company, you do not need to worry about your data ever getting damaged. We can guarantee that because our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. All information that you upload will be stored in a RAID i.e. simultaneously on multiple SSDs. All of the file systems synchronize the files between the different drives with such a setup, but there's no real guarantee that a file won't be corrupted. This can occur during the writing process on any drive and afterwards a corrupted copy can be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all of the drives immediately and in the event that a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. By doing this, your information will stay undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any risk of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created use a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we store all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. In the event that there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and considering that it happens in real time, there is no chance that a corrupted copy could remain on our hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems use this type of checks and furthermore, even during a file system check right after a sudden blackout, none of them will detect silently corrupted files. In contrast, ZFS does not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unneeded.
