Data corruption is the damage of info caused by various hardware or software problems. The moment a file gets damaged, it will no longer work correctly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as problems are very likely to occur on larger in size hard disk drives where considerable volumes of info are kept. When a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's likely that the bad file will be treated as a standard one and will be duplicated on all the drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often are not able to find corrupted files instantly or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Website Hosting

In case you host your Internet sites in a cloud website hosting account with our firm, you won't have to worry about any of your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the advanced ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All of the information that you upload will be stored in a RAID i.e. simultaneously on multiple SSDs. Many file systems synchronize the files between the separate drives using this type of a setup, but there's no real guarantee that a file won't get corrupted. This could occur during the writing process on each drive and after that a bad copy may 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 drives instantly and when a corrupted file is found, it's substituted with a good copy with the correct checksum from another drive. This way, your info 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 shielded from silent data corruption as all our storage servers use the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it'll be saved on several redundant drives operating in a RAID i.e. the files shall be the same across all drives. All copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, so if it registers a mismatch, that would indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other disks. Even if there's an unexpected blackout, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, lengthening the time needed for the server to go back online. ZFS is the only file system that can truly protect your content from silent data corruption.
