Data corruption is the damage of data caused by various software or hardware fails. After a file gets corrupted, it will no longer function accurately, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for hosting servers as fails are very likely to happen on larger in size hard disks where large volumes of information are kept. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's very likely that the bad file will be treated as an undamaged one and it will be copied on all of the drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often are unable to discover corrupted files immediately or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Hosting

If you host your Internet sites in a shared hosting account from our firm, you won't need to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform works with the outstanding ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. All the information that you upload will be saved in a RAID i.e. simultaneously on many different SSDs. All the file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file won't be corrupted. This can happen during the writing process on each drive and then a bad copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives right away and if a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. In this way, your information will continue to be undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. In the event that there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens right away, 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 work with this type of checks and furthermore, even during a file system check following an unexpected blackout, none of them will discover silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the regular checksum monitoring makes a lenghty file system check unneeded.
