Data corruption is the damage of data because of various software or hardware failures. After a file is damaged, it will no longer work accurately, so an app will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, that makes it a significant problem for website hosting servers as fails are much more likely to happen on larger hard disk drives where considerable volumes of info are placed. In case a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it is more than likely that the bad file will be treated as an undamaged one and it will be duplicated on all drives, making the damage permanent. A huge number of the file systems which operate on web servers these days often are not able to discover corrupted files immediately or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data which you upload to your new cloud web hosting account shall be guaranteed by the ZFS file system which we take advantage of on our cloud platform. Most web hosting suppliers, including our firm, use multiple hard disk drives to keep content and since the drives work in a RAID, the same data is synchronized between the drives all of the time. If a file on a drive is corrupted for reasons unknown, however, it is very likely that it will be copied on the other drives since other file systems do not feature special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the damaged copy will be replaced with a good one from a different hard disk drive. Because this happens right away, there's no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not experience any silent data corruption issues in case you get one of our semi-dedicated hosting plans as the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all of the files are intact all of the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. As we store all content on a number of drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the damaged copy to be synchronized on the other hard disks. ZFS is the only file system available on the market that uses checksums, which makes it far superior to other file systems that are unable to detect silent data corruption and duplicate bad files across drives.
