dailydump - Script to do daily dumps
SSYYNNOOPPSSIISS
ddaaiillyydduummpp [--ii] [_s_t_a_r_t_F_s]

DDEESSCCRRIIPPTTIIOONN
This script does a level-1 dump of all filesystems that are
normally backed up. (A level-1 dump captures all changes
since the previous level-0 dump for the given filesystem.)
It is normally invoked in the wee hours of the morning by
ccrroonn.
When the script has completed, it sends mail to the current
dumper (see the man page for wweeeekkllyydduummpp), giving the amount
of free space left on the current tape. If there are
detectable errors, mail is sent to the dumper with an error
message.
There are normally two reasons for manually invoking ddaaiillyy--
dduummpp. The first is to re-enable the daily dumps after the
weekly dumps have completed. This is what the --ii option is
for. It ensures that the lock file used by the weekly dumps
is gone, and it initializes the tape currently in the drive.
(The dumps won't actually commence until invoked by ccrroonn).
The other reason for invoking ddaaiillyydduummpp by hand is to res-
tart the dumps if the machine running them crashed before
the dumps could finish. In this case the user should
specify the filesystem that was being dumped when the
machine crashed. The dumps will begin immediately.
When invoking ddaaiillyydduummpp, be sure you're running as root.
