Data corruption is the damage of info due to various hardware or software failures. Once a file gets corrupted, it will no longer work properly, so an app will not start or will give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, that makes it a serious problem for website hosting servers as failures are more likely to occur on bigger hard drives where considerable volumes of info are stored. In case a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the bad file will be treated as an ordinary one and will be copied on all of the drives, making the damage permanent. A huge number of the file systems that operate on web servers these days often are unable to find corrupted files immediately or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Shared Hosting
If you host your websites in a shared hosting account with our company, you will not need to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform uses the amazing ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All information that you upload will be kept in a RAID i.e. simultaneously on numerous SSD drives. All the file systems synchronize the files between the separate drives using such a setup, but there is no real guarantee that a file will not be corrupted. This may happen at the time of the writing process on any drive and afterwards a damaged copy can be copied on the other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all the drives immediately and in the event that a corrupted file is located, it's swapped with a good copy with the correct checksum from another drive. This way, your info will stay unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be protected against silent data corruption as all our storage servers make use of the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it will be kept on a couple of redundant drives employed in a RAID i.e. the files will be the same on all disk drives. All copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the copies in real time, and if it detects a mismatch, that would indicate that one of the copies is corrupted, it'll replace that file with a good copy from one of the other drives. Even if there's an unforeseen power failure, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform after some malfunction, extending the time needed for the server to get back online. ZFS is the file system that can really protect your content from silent data corruption.
