### FAQ > 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? Read how to [restore a previously saved environment](https://github.com/tmux-plugins/tmux-resurrect/blob/master/docs/restoring_previously_saved_environment.md) > 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."](https://github.com/tmux-plugins/tmux-resurrect/blob/da1a7558024b8552f7262b39ed22e3d679304f99/scripts/save.sh#L271-L277) > 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.
