Data corruption is the unintentional modification of a file or the losing of information which often occurs during reading or writing. The reason may be hardware or software fail, and for that reason, a file can become partially or fully corrupted, so it will no longer function as it should because its bits will be scrambled or missing. An image file, for instance, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. If this kind of an issue occurs and it isn't found by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive that is part of a RAID array where the data is synced between various drives, the corrupted file shall be copied on all the other drives and the damage will be long term. Numerous popular file systems either don't feature real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a very common matter on internet hosting servers where substantial amounts of data are stored.

No Data Corruption & Data Integrity in Shared Website Hosting

If you host your sites in a shared website hosting account from our company, you do not have to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform employs the outstanding ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. Any info that you upload will be kept in a RAID i.e. simultaneously on numerous SSD drives. All file systems synchronize the files between the different drives using such a setup, but there's no real warranty that a file won't get corrupted. This can occur throughout the writing process on each drive and after that a bad copy can be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives right away and when a corrupted file is discovered, it's replaced with a good copy with the correct checksum from some other drive. This way, your info will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created work with 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. Since 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 stored. In case there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and because it happens in real time, there's no chance that a damaged copy can remain on our web servers or that it can be copied to the other hard drives in the RAID. None of the other file systems include this type of checks and what's more, even during a file system check following a sudden power loss, none of them will detect silently corrupted files. In contrast, ZFS will not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
