Data corruption is the unintended modification of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software malfunction, and as a result, a file could become partially or fully corrupted, so it'll no longer function correctly as its bits will be scrambled or lost. An image file, for instance, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. When this kind of a problem appears and it's not recognized by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive that is part of a RAID array where the information is synced between various different drives, the corrupted file shall be reproduced on all other drives and the damage will become permanent. Many frequently used file systems either do not offer real-time checks or don't have high quality ones which can detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where huge volumes of information are stored.

No Data Corruption & Data Integrity in Web Hosting

In case you host your sites in a web hosting account with our company, you won't have to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform employs the amazing ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be saved in a RAID i.e. simultaneously on a large number of NVMes. All of the file systems synchronize the files between the separate drives with such a setup, but there is no real guarantee that a file won't get corrupted. This could happen at the time of the writing process on each drive and after that a damaged copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all drives immediately and if a corrupted file is identified, it's swapped with a good copy with the correct checksum from some other drive. By doing this, your data will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption since all of our storage servers use the advanced ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it'll be saved on a couple of redundant drives employed in a RAID i.e. the files will be the same on all disks. All the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, so if it identifies a mismatch, which would indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other drives. Even if there is a sudden power loss, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check which other file systems perform after some malfunction, prolonging the time needed for the server to get back online. ZFS is the only file system which can truly protect your content from silent data corruption.
