Backup Ext2, Ext3, or Ext4 File Systems in Linux

The implementation of the Ext2 file system overcame the limitations posed by Ext; the original Linux file system. Ext2 does not support any journaling feature, has 16GB to 2TB maximum individual file size, and 2TB to 32TB being its overall file system size.

When considering the creation of backups for Ext2, Ext3, and Ext4 file systems in Linux, it is important to go with an effective and reliable tool.

The dump program is an ideal candidate for creating backups of these file systems because of the following prime features:

  • Supports remote backup.
  • If you do not want to back up the whole filesystem, you can back up a section of the file system like Home, Documents, or Downloads.
  • Removable media backups span multiple volumes.
  • Supports incremental, differential, and full backups.
