# Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any').# # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 a.m every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/ # # For more information see the manual pages of crontab(5) and cron(8) # # m h dom mon dow command # delete old snapshots once per day at 1am 0 1 * * * /usr/local/bin/zfsnap.sh destroy -r bup/projects 0 1 * * * /usr/local/bin/zfsnap.sh destroy -r bup/bups # make a snapshot every 10 minutes, which gets kept for 3 days: 432 total snapshots */10 * * * * /usr/local/bin/zfsnap.sh snapshot -a 3d -r bup/projects # make a snapshot every hour, which gets kept for 5 days: 120*2 = 240 snapshots 0 * * * * /usr/local/bin/zfsnap.sh snapshot -a 5d -r bup/projects 0 * * * * /usr/local/bin/zfsnap.sh snapshot -a 5d -r bup/bups # make a snapshot at midnight that is kept for 1 month: 30*2 = 60 snapshots 0 0 * * * /usr/local/bin/zfsnap.sh snapshot -a 30d -r bup/projects 0 0 * * * /usr/local/bin/zfsnap.sh snapshot -a 30d -r bup/bups
