Data corruption is the damage of info caused by various software or hardware failures. The moment a file is corrupted, it will no longer work properly, so an app will not start or shall give errors, a text file can be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as failures are much more likely to occur on larger hard disk drives where vast volumes of information are placed. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a regular one and it will be duplicated on all drives, making the harm permanent. Lots of the file systems which operate on web servers today often cannot recognize corrupted files right away or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your websites in a cloud hosting account from our company, you will not need to worry about any of your data ever getting corrupted. We can ensure that as our cloud hosting platform uses the amazing ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any data that you upload will be saved in a RAID i.e. simultaneously on multiple SSDs. A lot of file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file won't be corrupted. This could happen during the writing process on each drive and afterwards a corrupted copy may be copied on all other drives. What is different on our platform is that ZFS examines the checksums of all files on all drives instantly and if a corrupted file is identified, it's replaced with a good copy with the correct checksum from some other drive. By doing this, your information will stay undamaged 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 resistant to silent data corruption as all of our storage servers use the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of every single 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 will be the same on all disk 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 in real time, and if it registers a mismatch, that would indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other disks. Even if there is an unforeseen power loss, the data on the servers won't be 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 go back online. ZFS is the sole file system that can truly protect your content from silent data corruption.
