Data corruption is the unintended transformation of a file or the loss of info which often occurs during reading or writing. The reason may be hardware or software failure, and as a result, a file can become partially or entirely corrupted, so it'll no longer function correctly since its bits will be scrambled or lacking. An image file, for instance, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. If this kind of a problem appears and it isn't recognized by the system or by an admin, the data will be corrupted silently and if this happens on a drive that's a part of a RAID array where the data is synced between various drives, the corrupted file will be duplicated on all the other drives and the harm will be long term. A number of commonly used file systems either do not feature real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common problem on web hosting servers where huge volumes of info are kept.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your websites in a cloud hosting account from our firm, you will not have to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be stored in a RAID i.e. simultaneously on numerous SSDs. All the file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file won't be corrupted. This may occur during the writing process on any drive and afterwards a damaged copy can be copied on the other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives immediately and in the event that a corrupted file is located, it is substituted with a good copy with the correct checksum from some other drive. In this way, your information will stay intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any possibility of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created take advantage of a powerful file system known as ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. As we save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In case there is 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's no chance that a corrupted copy could remain on our web hosting servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems work with such checks and what's more, even during a file system check after an unexpected blackout, none of them can find silently corrupted files. In comparison, ZFS does not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unneeded.
