Data corruption is the damage of info because of various software or hardware problems. The moment a file is damaged, it will no longer function as it should, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, that makes it a serious problem for hosting servers as failures are much more likely to happen on larger in size hard drives where substantial volumes of info are kept. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is more than likely that the bad file will be treated as a standard one and it will be copied on all drives, making the damage permanent. A huge number of the file systems that operate on web servers nowadays often cannot find corrupted files in real time or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Hosting
If you host your websites in a hosting account from our firm, you do not have to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the state-of-the-art ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be stored in a RAID i.e. simultaneously on numerous SSDs. All file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file won't get corrupted. This could happen at the time of the writing process on each drive and afterwards a bad copy may be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives instantly and in case a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. That way, your data 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 use the effective ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of every single file. When you upload content to your account, it will be stored on a couple of redundant drives employed in a RAID i.e. the files shall be the same across all drives. All the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, and if it detects a mismatch, that will indicate that one of the copies is damaged, it will replace 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 will not be any need for a time-consuming system check that other file systems perform after some malfunction, lengthening the time needed for the server to get back online. ZFS is the file system which can really protect your content from silent data corruption.
