Data corruption is the damage of information due to various software or hardware problems. When a file gets corrupted, it will no longer function properly, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive 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 administrator, that makes it a serious problem for web hosting servers as problems are more likely to occur on bigger hard disk drives where considerable volumes of information are kept. If a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a standard one and it will be duplicated on all drives, making the damage permanent. A lot of the file systems that run on web servers today often are unable to find corrupted files in real time or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Website Hosting
If you host your Internet sites in a website hosting
account from our firm, you will not have to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform employs the outstanding ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. All of the information that you upload will be saved in a RAID i.e. simultaneously on multiple SSD drives. All the file systems synchronize the files between the different drives with this kind of a setup, but there's no real warranty that a file won't be corrupted. This could happen throughout the writing process on any drive and after that a corrupted copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all the drives instantly and in case a corrupted file is identified, it's replaced with a good copy with the correct checksum from some other drive. In this way, your info will stay intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be resistant to silent data corruption because all our storage servers employ the innovative ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to verify the integrity of each file. When you upload content to your account, it'll be placed on a couple of redundant drives being employed in a RAID i.e. the files will be the same on all disk drives. All of the copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it discovers a mismatch, which would indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other disks. Even if there's a sudden power failure, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, prolonging the time needed for the server to get back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
