zmschedulebackup

This command is used to schedule backups and add the command to your cron table.

The default schedule is as follows:

•	Full backup, every Saturday at 1:00 a.m. (0 1 * * 6)

•	Incremental backup, Sunday through Friday at 1:00 a.m. (0 1 * * 0-5)

Each crontab entry is a single line composed of five fields separated by a blank space. Specify the fields as follows:

•	minute — 0 through 59

•	hour — 0 through 23

•	day of month — 1 through 31

•	month — 1 through 12

•	day of week — 0 through 7 (0 or 7 is Sunday, or use names)

Type an asterisk (*) in the fields you are not using.

This command automatically writes the schedule to the crontab.
