Data corruption is the damage of information due to various software or hardware fails. Once a file gets corrupted, it will no longer work accurately, so an application will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, which makes it a significant problem for website hosting servers as problems are much more likely to happen on larger hard disks where large volumes of info are kept. When a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a good one and it'll be duplicated on all drives, making the damage permanent. A huge number of the file systems which run on web servers today often are not able to detect 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
In case you host your sites in a shared hosting
account from our firm, you don't need to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. All info that you upload will be saved in a RAID i.e. simultaneously on a number of SSD drives. All file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file will not be corrupted. This may happen throughout the writing process on each drive and afterwards a bad copy may be copied on the other drives. What is different on our platform is that ZFS examines the checksums of all files on all drives instantly and when a corrupted file is located, it's swapped with a good copy with the correct checksum from some other drive. By doing this, your information will continue to be unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be protected against silent data corruption since all our storage servers make use of the efficient ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each and every file. When you upload content to your account, it'll be stored on a couple of redundant drives employed in a RAID i.e. the files shall be the same across all drives. All of the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, and if it identifies a mismatch, that will indicate that one of the copies is damaged, it'll substitute that file with a healthy copy from one of the other drives. Even if there is an unexpected power failure, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check which other file systems perform after some breakdown, lengthening 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.
