thanks @1o1o1
Tmux 2.9 has removed some options:

The force-width and force-height options and the session_width and session_height formats have been removed.

The old backups can still be restored, however, the backup operation fails due to the usage of the removed options. I'll take a closer look at the problem and fix it.

@1o1o1 pushed a fix (v.1.0.3) in the master branch. You can give it a try.

Working ok) but when restore backup, programs not running automatically :(

[sk1418]

If you meant the “programs “ is tmux, then it is fine. Because retmux restores sessions in detached mode. If you want to attach after the restore, you can try retmux -r xxx && tmux attach @1o1o1

i meant apps running in windows of terminals tmux!

@1o1o1 I don't get you. sorry.
If you restore a backup inside an active tmux session, it should work too. You can use the list-session or prefix-s to see the restored sessions.
If it was not what you meant, can you please tell me what did you do in each step?
Or give this a try:

• first backup sessions from the current tmux using retmux -b with or without name
• if the backup is well done, run tmux kill-server (kill the tmux)
• run retmux -r && tmux attach
• Can you see your backup sessions get restored?
  I tested once yesterday, it works. Of course, probably, I could miss something.
