Data corruption is the damage of info because of various hardware or software problems. Once a file is damaged, it will no longer work correctly, so an app will not start or will give errors, a text file can be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a serious problem for hosting servers as fails are very likely to happen on larger hard disks where vast volumes of information 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's more than likely that the damaged file will be treated as a healthy one and it will be copied on all of the drives, making the damage permanent. Lots of the file systems that operate on web servers today often are unable to discover corrupted files right away or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Website Hosting
If you host your Internet sites in a website hosting
account from our firm, you don't need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform works with the leading-edge ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. All the info that you upload will be stored 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 will not get corrupted. This may happen during the writing process on each drive and after that a corrupted copy may be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives right away and when a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. That way, your information will remain intact 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 because all our storage servers make use of the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of every single file. When you upload content to your account, it will be stored on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all drives. All copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, and if it detects a mismatch, which will indicate that one of the copies is corrupted, it will replace that file with a good copy from one of the other drives. Even if there's a sudden power failure, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some malfunction, prolonging the time needed for the server to get back online. ZFS is the only file system which can really protect your content from silent data corruption.
