Will a previous save be overwritten immediately after I start tmux?
No, first automatic save starts 15 minutes after tmux is started. If automatic restore is not enabled, that gives you enough time to manually restore from a previous save.
I want to make a restore to a previous point in time, but it seems that save is now overwritten?

Will this plugin fill my hard disk?
Most likely no. A regular save file is in the range of 5Kb. And tmux-resurrect already has a remove_old_backups() routine that will "remove resurrect files older than 30 days, but keep at least 5 copies of backup."
How do I change the save interval to i.e. 1 hour?
The interval is always measured in minutes. So setting the interval to 60
(minutes) will do the trick. Put this in .tmux.conf:
set -g @continuum-save-interval '60'
and then source tmux.conf by executing this command in the shell
$ tmux source-file ~/.tmux.conf.
How do I stop automatic saving?
Just set the save interval to 0. Put this in .tmux.conf
set -g @continuum-save-interval '0'
and then source tmux.conf by executing this command in the shell
$ tmux source-file ~/.tmux.conf.
I had automatic restore turned on, how do I disable it now?
Just remove set -g @continuum-restore 'on' from tmux.conf.
To be absolutely sure automatic restore doesn't happen, create a
tmux_no_auto_restore file in your home directory (command:
$ touch ~/tmux_no_auto_restore). Automatic restore won't happen if this file
exists.
