to 3 hours each. Weekly and monthly backups may take longer. These numbers may vary.
After the initial backup, the backup process transfers only files that have changed since the last backup.
Thus, subsequent backups should take less time than the initial backup. The time required for subsequent
backups depends on the amount of data accumulated, how many files have changed, and to what extent
the files have changed since the last backup.

Note
You can schedule a backup from a larger source to a smaller target Security
Management appliance as long as there is enough space on the target for all
of the data being backed up. For example, if the source appliance is an
M1060 and a smaller M650 is the target, you must reduce the space allocated
on the larger M1060 to match the space available on the smaller M650
appliance. See
