Data corruption is the unintended change of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software fail, and due to this fact, a file could become partially or fully corrupted, so it'll no longer function correctly because its bits will be scrambled or lost. An image file, for instance, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. When such an issue appears and it isn't identified by the system or by an administrator, the data will be corrupted silently and when this happens on a drive that's a part of a RAID array where the data is synced between various drives, the corrupted file shall be duplicated on all of the other drives and the damage will be permanent. Many widely used file systems either do not offer real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where substantial amounts of data are kept.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your sites in a shared website hosting account with our company, you don't have to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the info that you upload will be kept in a RAID i.e. simultaneously on a large number of SSDs. All the file systems synchronize the files between the separate drives with this kind of a setup, but there is no real guarantee that a file will not be corrupted. This may occur at the time of the writing process on each drive and afterwards a damaged copy can be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives in real time and when a corrupted file is discovered, it is replaced with a good copy with the correct checksum from some other drive. By doing this, your information will stay unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption since all our storage servers employ the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to guarantee the integrity of every single file. When you upload content to your account, it will be placed on a couple of redundant drives operating in a RAID i.e. the files will be the same across all disk drives. All of the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies quickly, and if it finds a mismatch, which will indicate that one of the copies is corrupted, it'll swap that file with a good copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, lengthening the time needed for the server to go back online. ZFS is the sole file system that can really protect your content from silent data corruption.
