The process of files getting corrupted caused by some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face as the larger a hard disk is and the more info is kept on it, the much more likely it is for data to get corrupted. You'll find a couple of fail-safes, yet often the data is corrupted silently, so neither the particular file system, nor the admins notice a thing. Because of this, a damaged file will be handled as a regular one and if the hard drive is part of a RAID, that particular file will be copied on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get worse. When some file gets corrupted, it will be partially or completely unreadable, which means that a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your website content. Although the most frequently used server file systems feature various checks, they often fail to identify some problem early enough or require an extensive amount of time in order to check all the files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Shared Website Hosting
If you host your Internet sites in a shared website hosting account with our company, you won't have to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform employs the leading-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All data that you upload will be kept in a RAID i.e. simultaneously on multiple SSDs. All the file systems synchronize the files between the different drives using such a setup, but there's no real warranty that a file will not be corrupted. This may happen during the writing process on any drive and after that a corrupted copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all drives right away and in the event that a corrupted file is identified, it is swapped with a good copy with the correct checksum from another drive. By doing this, your info will stay 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 shielded from silent data corruption because all of our storage servers use the effective ZFS file system. What makes the aforementioned 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 will be placed on a couple of redundant drives 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 drives and ZFS will compare the checksums of the duplicates right away, and if it finds a mismatch, which will indicate that one of the copies is damaged, it will replace that file with a healthy copy from one of the other disks. Even if there's 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 following some breakdown, extending the time needed for the server to return online. ZFS is the sole file system which can truly protect your content from silent data corruption.
