Data corruption is the damage of info due to various software or hardware problems. After a file is damaged, it will no longer work correctly, so an application will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an administrator, which makes it a significant problem for web hosting servers as failures are much more likely to occur on bigger hard drives where large volumes of information are kept. In case a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as a good one and it will be duplicated on all drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often are not able to discover corrupted files instantly or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your websites in a cloud hosting account from our company, you do not have to worry about your data ever getting damaged. We can guarantee that because our cloud hosting platform works with the state-of-the-art ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All of the data that you upload will be saved in a RAID i.e. simultaneously on numerous SSD drives. Many file systems synchronize the files between the separate drives with this kind of a setup, but there is no real warranty that a file will not get corrupted. This could happen at the time of the writing process on any drive and afterwards a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives immediately and if a corrupted file is discovered, it is replaced with a good copy with the correct checksum from some other drive. This way, your info will remain intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not encounter any kind of silent data corruption issues whatsoever should you purchase one of our semi-dedicated hosting solutions due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to guarantee that all files are intact all of the time. A checksum is a unique digital fingerprint that is given to each and every file saved on a server. Due to the fact that we store all content on a number of drives simultaneously, 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. 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 bad copy to be synchronized on the other hard drives. ZFS is the sole file system you can get that uses checksums, which makes it far superior to other file systems that are not able to detect silent data corruption and duplicate bad files across hard drives.
