Data corruption is the accidental transformation of a file or the loss of info that 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 as its bits will be scrambled or missing. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. In the event that this kind of an issue appears and it isn't recognized by the system or by an administrator, the data will become corrupted silently and when this happens on a disk drive that's a part of a RAID array where the information is synced between various different drives, the corrupted file will be reproduced on all other drives and the harm will be long term. Numerous widespread file systems either do not have real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a very common issue on web hosting servers where large volumes of info are kept.

No Data Corruption & Data Integrity in Hosting

We guarantee the integrity of the information uploaded in every single hosting account which is made on our cloud platform as we use the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption via a unique checksum for each file. We shall store your data on a large number of NVMe drives that operate in a RAID, so the exact same files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file differs from what it should be, the file system replaces that file with a healthy version from a different drive inside the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption as all of our storage servers make use of the innovative ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to ensure the integrity of each file. When you upload content to your account, it will be saved on several redundant drives working in a RAID i.e. the files will be the same across all drives. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, so if it discovers a mismatch, that would indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other disks. Even if there's an unexpected power loss, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, prolonging the time needed for the server to go back online. ZFS is the file system which can truly protect your content from silent data corruption.
