- Thanks for all the responses on my plead for help on getting the cron to run my
- backup script using the dump command.
-
-
- It turned out to be very simple, I just needed to supply the full path to the
- dump command, i.e. /etc/dump, I ought to have though of that.
-
- My other problem with not being able to redirect the output from the dump
- command to a file was solved by doing the redirection in the entry in the
- /etc/crontab,
- as in:
-
- 0 23 * * 1-5 root /usr/local/bin/daily.backup >/tmp/backup.last 2>&2
-
- why that worked while I couldn't do redirect on the dump command itself, is
- strange, but the above suits me fine.
-
- Some responses wondered whether my dump parameters were ok, specifically that I
- didn't specify the filesystem parameter. The manpages states which fileystem
- is the default (/dev/rsd0a) under the FILES header.
-
- The working 'dump' command is thus after several experiments:
-
- /etc/dump 0fsd /dev/rst0 2750 640000
-
- By the way, I am using an HP6400/2000 DAT drive, which is device /dev/rst0
