Data corruption is the accidental transformation of a file or the loss of info that often occurs during reading or writing. The reason can be hardware or software fail, and as a consequence, a file could become partially or fully corrupted, so it'll no longer work as it should because its bits shall be scrambled or lost. An image file, for instance, will no longer display an actual image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. If such a problem appears and it isn't recognized by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the information is synced between different drives, the corrupted file will be copied on all the other drives and the harm will be long term. Many widely used file systems either don't feature real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a very common problem on hosting servers where large amounts of information are kept.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the information uploaded in every shared hosting account which is created on our cloud platform because we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for each file. We shall store your info on a number of SSD drives that function in a RAID, so the exact same files will be available on several places at the same time. ZFS checks the digital fingerprint of all of the files on all drives in real time and in case the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged copy from another drive inside the RAID. There's no other file system which uses checksums, so it's possible for data to become silently corrupted and the bad file to be duplicated on all drives over time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption as 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 each file. When you upload content to your account, it'll be placed on a couple of redundant drives being employed in a RAID i.e. the files shall be the same on all drives. All the copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the copies in real time, and if it finds a mismatch, that will indicate that one of the copies is damaged, it'll substitute that file with a healthy copy from one of the other drives. Even if there is an unforeseen power failure, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, extending the time needed for the server to get back online. ZFS is the only file system that can really protect your content from silent data corruption.
