Data corruption is the damage of data because of various software or hardware problems. Once a file gets corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for web hosting servers as problems are very likely to happen on bigger hard disks where large volumes of information are kept. In case a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's likely that the bad file will be treated as a regular one and it will be duplicated on all of the drives, making the damage permanent. Lots of the file systems which run on web servers these days often are unable to identify corrupted files right away or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the information uploaded in any cloud hosting account that is generated on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption using a unique checksum for each file. We'll store your info on a large number of NVMe drives that operate in a RAID, so exactly the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file is different from what it needs to be, the file system replaces that file with an undamaged version from another drive within the RAID. There's no other file system which uses checksums, so it's possible for data to be silently corrupted and the bad file to be reproduced on all drives with time, but since this can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption since all of our storage servers employ the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as 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 being employed in a RAID i.e. the files will be the same on all disk drives. All the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies in real time, so if it finds a mismatch, which would indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other disks. Even if there's a sudden power loss, the data on the servers will not be corrupted and there won't 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 get back online. ZFS is the file system that can truly protect your content from silent data corruption.
