- 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.
