Hi, I'm working on a service/program for Linux which takes care of managing backupping of folders and the snapshots of those. The user can assign forlders he/she want to be backupped (corect English?), and create a profile for this folder. This profile is about the files which will be taken into process, and which not. As tool to backup and manage the snapshots I use btrfs. Now in my construction I get a lot of situations like: /path/to/snapshots/201501261603/path/to/some/file is another version of the same file at: /path/to/snapshots/201501252252/path/to/some/file is there a way to get the difference between these two files by making use of btrfs? I know there are "high level" tools like diff, and tools that fit with the mimetype of the file (for ODT files you need another tool than say plaintext files) I know there is a tool like btrfs send / receive, but that count for whole snapshots. If there is such a tool, the next step would be whether it's possible to provide the user comprehensive information what has changed in the file, when the mimetype is something else than plaintext, but that's another question.
