It depends. Dump makes an image of a file system. While this is a belt-and-braces approach (i.e. you can be certain that file metadata, extended attributes, deleted files etc are backed up), it's often viewed as inefficient. What if, for example, you want to use the back up to migrate to a different file system. What if you want a more space-efficient backup (do you REALLY need to dump those hundreds of gigabytes of empty space?). > i checked out luckybackup , but it just copies files (backs them up) .... A file-based backup is generally preferred. I can't speak for luckybackup, but a good file-based backup system should back up all your files. It should also handle xattrs, acls etc if those are important to you. In theory, the files are all you really need for a backup. To restore for bare metal, you would partition the disks as appropriate, restore the latest backup, re-install the bootloader (as the MBR is typically not included in a file-based backup) and reboot. > thanks ...
