The process of files being damaged as a result of some hardware or software failure is called data corruption and this is among the main problems which web hosting companies face because the larger a hard disk drive is and the more data is placed on it, the much more likely it is for data to get corrupted. There are different fail-safes, yet often the information gets corrupted silently, so neither the file system, nor the administrators notice a thing. Because of this, a bad file will be treated as a good one and if the HDD is a part of a RAID, that file will be duplicated on all other drives. Theoretically, this is for redundancy, but in reality the damage will get even worse. When some file gets damaged, it will be partially or entirely unreadable, so a text file will no longer 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 commonly used server file systems have various checks, they frequently fail to discover some problem early enough or require an extensive time period to be able to check all of the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Hosting

We have tackled the matter of silent data corruption on all of our hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one out there that checks all the files right away by using a checksum - a digital identifier which is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and constantly synced between them for redundancy. ZFS constantly compares the checksum of all files and in the event that any file is detected as damaged, it is replaced right away with a good copy from another disk. As this happens in real time, there is no risk that a bad file may remain or may be copied on the other SSDs. ZFS requires plenty of physical memory to perform the real-time checks and the benefit of our cloud website hosting platform is that we employ multiple very powerful servers working together. In case you host your websites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all of our storage servers make use of the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to verify the integrity of each file. When you upload content to your account, it will be saved on a couple of redundant drives in a RAID i.e. the files will be the same on all drives. All copies of a particular file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it finds a mismatch, which would indicate that one of the copies is corrupted, it'll replace that file with a good copy from one of the other drives. Even if there is a sudden blackout, 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 failure, prolonging the time needed for the server to return online. ZFS is the file system which can truly protect your content from silent data corruption.
