+Since backup to external drive requires human intervention anyway (pick

+
+This set of scripts includes some scripts which simplify semiregular
+backups on removable drive. 
+
+1. **backup** - perl script which checks if there are enough backups on
+level alpha done and it's time to do next level beta backup.
+It reads `/etc/rsnapshot.conf` for `snapshot_root` and `retain`
+parameters. After successful backup it unmounts backup drive.
+
+2. **aftermount** - this script inteneded to be run by automounting
+system in your desktop session (tested with spacewm). It runs after
+removable disk is mounted and checks if this disk contains
+`snapshot_root`. If so, it displays dialog window asking you if you want
+to run backup. If yes, it starts **backup** using sudo.
+
+3. **backup.sudo** - place this file into `/etc/sudoers.d` so
+**aftermount** would be able to run **backup** as root without password.
