| This is what I use to backup ALL my DVDs. I like it a lot. So much, that I have so far had zero interest in duplicating it's functionality in [[dvd_info]]. | * [[https://dvdbackup.sourceforge.net/|dvdbackup homepage]] |

| | The latest release of this is from 2012. You can still build it from source, but **it will break with modern libdvdread**. Use your package manager to install it (if it has it), as this will be patched to work properly. Alternatively, use [[dvd_backup]] from my [[dvd_info]] software packages. |

| ''dvdbackup'' will do a binary sort on the cell sectors when copying them. This can lead to copies that are not bit-exact or possibly have chapters that are out of order on one track (see dvdbackup.c bsort_min_to_max function). I'm guessing it's designed to make reads more efficient so it's not skipping back and forth. | ''dvdbackup'' will do a binary sort on the cell sectors when copying them.

| I'm not sure if this is a real problem or not, I found it on one DVD that's fussy to rip anyway (DSNYR, track 3064), and I'd have to query a lot to see if it's common, and even more to see if it's problematic. | I'm not sure if this is a real problem or not, I found it on one DVD that's fussy to rip anyway (DSNYR, track 3064), and I'd have to query a lot to see if it's common, and even more to see if it's problematic. |
