As you already might have tried, just calling
isibackupis equivalent to calling
isibackup --helpand dows not yet create a backup. It shows isibackup call synapsis, which is
The simplest way to use ISiBackup is to call it with the backup and the indication of one set, like
isibackup --backup --set data_linux
ISiBackup records most of the parameters that were used in creating the backup as part of the backup. To do so, it creates a directory called _isibackup in the root of the backup target directory. (Rest to be written; contents of isibackup subdir on target)
During the backup run, ISiBackup display a pregress indication. It consists of exactly 101 steps (each of the percentage values from 0% to 100%) if there are more than 100 directories to backup, and less steps if there are less. Additionally, ISiBackup outputs the current directory name when it reaches one of the percentage steps. In between thes steps, it just outputs a "+" sign in case it created a new backup target file, and a "." sign in case it refreshed a backup target file. (Accordingly, the cumulated number of "+" and "." signs must equal the number of directories to backup).
