###Export and import crontab on multiple instances of Crontab UI.
If you want to run the same jobs on multiple machines simply export from one instance and import the same on the other. No SSH, No copy paste!
![export](http://2.bp.blogspot.com/-trpHt_etz5I/VX1NyElIicI/AAAAAAAABE4/GTZFBCfybLk/s1600/3.png)
![export](https://github.com/alseambusher/crontab-ui/raw/gh-pages/screenshots/import_db.png)
But make sure to take a backup before importing.
###See when the job is going to run next.
