Data corruption is the damage of data because of various software or hardware fails. Once a file gets corrupted, it will no longer function as it should, so an application will not start or will 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 information getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for web hosting servers as problems are very likely to happen on bigger hard disks where considerable volumes of information are stored. When a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as a regular one and will be copied on all of the drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often are unable to recognize corrupted files instantly or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your sites in a cloud hosting account from our firm, you don't have to worry about your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be kept in a RAID i.e. simultaneously on numerous SSD drives. Many file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file will not be corrupted. This could happen at the time of the writing process on each drive and afterwards a bad copy may be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all of the drives immediately and when a corrupted file is found, it's swapped with a good copy with the correct checksum from another drive. In this way, your information will stay unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not experience any silent data corruption issues if you purchase one of our semi-dedicated hosting packages since the ZFS file system that we work with on our cloud hosting platform uses checksums to ensure that all of the files are undamaged at all times. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Since we store all content on a number of drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 chance of the bad copy to be synchronized on the rest of the drives. ZFS is the only file system you can find that uses checksums, which makes it much more dependable than other file systems which are not able to detect silent data corruption and copy bad files across drives.
