Data corruption is the damage of info caused by various hardware or software fails. The moment a file is damaged, it will no longer function accurately, so an app will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as failures are much more likely to happen on bigger hard disks where substantial volumes of information are kept. When a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as an ordinary one and it'll be duplicated on all drives, making the damage permanent. A huge number of the file systems which operate on web servers today often are unable to discover corrupted files right away or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Website Hosting
If you host your websites in a website hosting
account with our company, you don't have to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any data that you upload will be stored in a RAID i.e. simultaneously on numerous SSDs. Many file systems synchronize the files between the different drives with this type of a setup, but there is no real guarantee that a file will not be corrupted. This could occur during the writing process on any drive and then a corrupted copy can be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives in real time and when a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. This way, your information will remain intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be protected against silent data corruption because all our storage servers make use of the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it'll be kept on several redundant drives being employed in a RAID i.e. the files will be the same on all disks. All the copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so if it identifies a mismatch, that would indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other drives. Even if there's an unforeseen power loss, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, prolonging the time needed for the server to go back online. ZFS is the only file system that can really protect your content from silent data corruption.
