Data corruption is the unintentional change of a file or the loss of info which often occurs during reading or writing. The reason may be hardware or software fail, and as a consequence, a file can become partially or entirely corrupted, so it will no longer work properly since its bits shall be scrambled or lost. An image file, for instance, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In case such an issue appears and it's not found by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that is a part of a RAID array where the data is synchronized between different drives, the corrupted file will be duplicated on all of the other drives and the damage will be long term. Numerous widely used file systems either do not have 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 common issue on web hosting servers where substantial amounts of information are stored.

No Data Corruption & Data Integrity in Shared Hosting

If you host your websites in a shared hosting account with our company, you do not need to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the advanced ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any information that you upload will be saved in a RAID i.e. simultaneously on multiple NVMe drives. A lot of file systems synchronize the files between the different drives with such a setup, but there's no real guarantee that a file will not get corrupted. This could happen at the time of the writing process on each drive and then a damaged copy can be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives in real time and in the event that a corrupted file is located, it's substituted with a good copy with the correct checksum from another drive. In this way, your data will remain undamaged 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 resistant to silent data corruption because all our storage servers make use of the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to verify the integrity of every single file. When you upload content to your account, it will be saved on a couple of redundant drives in a RAID i.e. the files shall be the same on 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 duplicates in real time, so if it finds a mismatch, which would indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other drives. Even if there's a sudden power failure, 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 following some failure, lengthening the time needed for the server to go back online. ZFS is the file system which can really protect your content from silent data corruption.
