Data corruption is the accidental modification of a file or the losing of info which often occurs during reading or writing. The reason may be hardware or software malfunction, and as a result, a file can become partially or completely corrupted, so it will no longer function correctly since its bits shall be scrambled or missing. An image file, for example, will no longer present an accurate image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If this kind of an issue occurs and it's not noticed by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the info is synchronized between different drives, the corrupted file shall be duplicated on all of the other drives and the damage will be long term. A large number of popular file systems either do not feature real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where large volumes of info are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

In case you host your websites in a shared web hosting account with our company, you won't have to worry about your data ever getting corrupted. We can guarantee that because our cloud hosting platform works with the reliable ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on a large number of SSDs. Many file systems synchronize the files between the separate drives using this kind of a setup, but there is no real warranty that a file won't get corrupted. This could occur throughout the writing process on each drive and afterwards a bad copy may be copied on the other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives in real time and when a corrupted file is located, it is substituted with a good copy with the correct checksum from some other drive. In this way, your data will continue to be unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't have to deal with any silent data corruption issues should you acquire one of our semi-dedicated server packages because the ZFS file system that we use on our cloud hosting platform uses checksums in order to guarantee that all the files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any possibility of the corrupted copy to be synchronized on the rest of the hard drives. ZFS is the sole file system on the market that uses checksums, which makes it much more dependable than other file systems which are unable to identify silent data corruption and copy bad files across drives.
