Data corruption is the damage of info due to various hardware or software failures. The moment a file is damaged, it will no longer work accurately, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as fails are very likely to occur on larger in size hard disk drives where significant volumes of information are placed. In case a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as an ordinary one and it will be copied on all the drives, making the damage permanent. A huge number of the file systems which run on web servers nowadays often are unable to detect corrupted files instantly 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 with our company, you won't need to worry about your data ever getting damaged. We can guarantee that because our cloud hosting platform works with the revolutionary ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All the data that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. All of the file systems synchronize the files between the separate drives using this kind of a setup, but there's no real warranty that a file will not get corrupted. This can happen during the writing process on each drive and afterwards a corrupted copy may be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives instantly and when a corrupted file is discovered, it's substituted with a good copy with the correct checksum from some other drive. That 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

In case you get one of our semi-dedicated hosting solutions, you won't have to be concerned about silent file corruption because we use ZFS - an advanced file system which monitors all of the files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done right away, so there will be no danger for any part of your content at any time. In contrast, other file systems perform checks after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a corrupted copy can be replicated on the remaining disks as well and you may lose important info. Because this is not the case with ZFS, we can guarantee the integrity of each file you upload no matter what.
