TerraMaster F2-223

Have a TerraMaster NAS? Here’s why you should use Snapshot and TFSS.



Ransomware is unfortunately a serious security risk many of us have to deal with on a daily basis. It’s almost impossible to ensure we’re all using 100% secure connections, adhering to best practices, and safely browsing online websites and apps. Thankfully, NAS brands such as TerraMaster are working hard to keep their NAS safe. Here’s how TerraMaster is doing it through snapshots and TFSS.

What is ransomware?

We’ve already carried out a deep dive into what precisely ransomware is, how it can affect you, your NAS, and your data, as well as how to better protect yourself from potential attacks. The gist of ransomware is a malicious attack from a third party that involves the encrypting of data. It can affect even the best NAS.

The decryption is then offered to the affected party for a disclosed sum, which is often not guaranteed to produce positive results. The very best way to shield oneself against ransomware is through backing up data. Then back up the backups. If you’re not fussed about losing one copy of affected files, there’s no opportunity for the criminals to make a quick buck.

Meet TerraMaster Snapshots and TFSS

TerraMaster TOS 5

TerraMaster has been working on protecting its customers for many years now and the company recently announced its Snapshot and TerraMaster File System Snapshot (TFSS) functionality of its TOS operating system for NAS. These handy features are not only useful for ransomware attacks but also drive failure and/or damage.

TerraMaster Snapshot is a disaster recovery tool developed on the btrfs file system. With this feature enabled and configured, it’s possible to take snapshots of shared folders or iSCSI LUNs for quick recovery should disaster strike. Based on copy-on-write (COW), Snapshot makes it easy to create instantaneous backups of stored data.

Up to 1,024 snapshots can be stored for each shared folder, as well as 65,536 for the entire filesystem. Each snapshot is stored on the same storage pool as the subvolume, making it possible to browse them much like you would a typical file directory, storing a particular file from when the snapshot was taken. They can also be transferred to external drives or remote systems for safekeeping.

TFSS takes things up a notch by taking a snapshot of the entire NAS file system. TFSS snapshot files are stored in a hidden directory with variable names and are read-only. they can be configured through the snapshot task scheduler to ensure an updated version of the TerraMaster NAS is ready to go should the worst-case scenario take place.
