Data corruption is the damage of data because of various software or hardware failures. After a file is corrupted, it will no longer work as it should, so an application will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open and 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 failures are more likely to happen on larger in size hard disk drives where significant volumes of info are located. In case a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's likely that the damaged file will be treated as an ordinary one and will be copied on all drives, making the damage permanent. Lots of the file systems that operate on web servers today often are unable to detect corrupted files instantly or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data that you upload to your new shared web hosting account will be ensured by the ZFS file system which we make use 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 exact same data is synchronized between the drives all the time. In case a file on a drive gets damaged for some reason, however, it is very likely that it will be reproduced on the other drives because alternative file systems do not have special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, which means that the damaged copy will be substituted with a good one from another disk drive. Because this happens immediately, there's no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not encounter any kind of silent data corruption issues in case you buy one of our semi-dedicated hosting solutions due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all files are undamaged all the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Since we store all content on multiple 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 in real time. If it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any possibility of the bad copy to be synchronized on the other drives. ZFS is the only file system you can find which uses checksums, which makes it much more dependable than other file systems that are unable to detect silent data corruption and duplicate bad files across hard drives.
