Data corruption is the unintended modification of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software malfunction, and consequently, a file can become partially or entirely corrupted, so it'll no longer function properly because its bits will be scrambled or missing. An image file, for instance, will no longer show an authentic image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. When this kind of an issue occurs and it isn't found by the system or by an admin, the data will be corrupted silently and when this happens on a drive that is part of a RAID array where the data is synchronized between various drives, the corrupted file will be copied on all other drives and the damage will become permanent. A number of widespread file systems either don't have real-time checks or don't have high quality ones which can detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your sites in a shared hosting account with our company, you will not have to worry about any of your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. Many file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file will not get corrupted. This could happen during the writing process on each drive and after that a bad copy may be copied on all other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives immediately and if a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. In this way, your data will stay 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 resistant to silent data corruption as all of our storage servers make use of the innovative ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to ensure the integrity of every single file. When you upload content to your account, it will be stored on a couple of redundant drives working in a RAID i.e. the files will be the same across all disks. All of the copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, so if it identifies a mismatch, which would indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other drives. Even if there is a sudden blackout, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check which other file systems perform following some malfunction, extending the time needed for the server to get back online. ZFS is the sole file system which can really protect your content from silent data corruption.
