Using the EXT3 file system on USB drives

Is it possible to use the EXT3 file system on USB storage devices connected to my Keenetic router?

Yes, it can. Keenetic router supports USB storage devices using the following EXT3 file system.
EXT3 is a journaling file system used in Linux kernel operating systems. EXT3 is one of the major file systems in many Linux distributions. EXT3 is based on the EXT2 file system and is fully compatible with it.
The main difference from EXT2 is that EXT3 is journaling, which means that some data is written in it, allowing the file system to be recovered in case of computer crashes.

The advantages of using the EXT3 file system:

  • Full compatibility with EXT2, making it very easy to migrate from EXT2 to EXT3 and vice versa, with no errors in the transition.
  • EXT3 has an option to recover deleted files or restore the file system.
  • The EXT3 file system can support files up to 2TB. It can support file names up to 255 characters long.
  • The EXT3 file system can make very efficient use of the free disk space. The EXT3 file system handles the hard disk so efficiently that disks usually do not need to be defragmented.
