Data corruption is the unintended modification of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file could become partially or entirely corrupted, so it'll no longer function correctly since its bits will be scrambled or missing. An image file, for instance, will no longer present an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. If this kind of a problem appears and it is not noticed by the system or by an admin, the data will get corrupted silently and in case this happens on a drive which is part of a RAID array where the data is synchronized between various drives, the corrupted file will be duplicated on all of the other drives and the harm will be permanent. Numerous commonly used file systems either do not have real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common matter on web hosting servers where large amounts of information are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

If you host your sites in a shared web hosting account with our company, you will not need to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform uses the advanced ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. All info that you upload will be kept in a RAID i.e. simultaneously on many SSD drives. All the file systems synchronize the files between the separate drives using this kind of a setup, but there is no real warranty that a file will not get corrupted. This may occur during the writing process on each 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 examines the checksums of all files on all the drives live and if a corrupted file is identified, it's swapped with a good copy with the correct checksum from another drive. In this way, your information will continue to be unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any chance of files getting damaged silently as the servers where your semi-dedicated server account will be created work with a powerful file system named ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we keep all content on a number of 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 case there is a mismatch, the bad copy is replaced with a good one from one of the other drives and since this happens right away, there's no chance that a corrupted copy could remain on our web servers or that it could be copied to the other hard drives in the RAID. None of the other file systems include this type of checks and what is more, even during a file system check after a sudden power loss, none of them will detect silently corrupted files. In comparison, ZFS does not crash after an electrical power failure and the constant checksum monitoring makes a time-consuming file system check unneeded.
