Data corruption is the damage of information caused by various software or hardware problems. When a file is corrupted, it will no longer function properly, so an app will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as failures are very likely to happen on bigger hard disk drives where considerable volumes of information are kept. When a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is more than likely that the damaged file will be treated as a standard one and it'll 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 locate 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
In case you host your websites in a shared web hosting
account from our firm, you don't have to worry about your data ever getting damaged. We can guarantee that because our cloud hosting platform employs the cutting-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any kind of information that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. All file systems synchronize the files between the different drives using such a setup, but there's no real warranty that a file will not get corrupted. This may happen at the time of the writing process on each drive and after that a damaged copy may be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives immediately and in case a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. This way, your info will continue to be intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not need to deal with any silent data corruption issues if you buy one of our semi-dedicated server
packages as the ZFS file system that we work with on our cloud hosting platform uses checksums to ensure that all the files are undamaged all of the time. A checksum is a unique digital fingerprint that is allotted to each and every file saved on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all of the 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 has to be, it replaces that file with a healthy copy without delay, avoiding any chance of the damaged copy to be synchronized on the rest of the hard disks. ZFS is the sole file system available on the market which uses checksums, which makes it much more reliable than other file systems that cannot identify silent data corruption and duplicate bad files across drives.
