#11 Ability to handle write errors if dump unsupervised

[Chris Maden]

I use dump/restore with a tape auto-changer.

Our backups take 30+ hours, so sitting at a console is
not an option. We therefore run dump as a cron job.
However, it sometimes happens that a tape in the
changer is bad (too old, low quality, whatever) which
causes a write error, at which point dump aborts and we
lose the backup.

This has happened quite a lot recently (we've just
watched a month go by without a backup because of write
errors on tapes from HP). So, it would be useful if
there was

a) an option, like the -F option, to execute a command
if dump hits a write error; or

b) the command specified in the -F option is called if
dump hits a write error; or

c) a new option which invokes the command specified by
the -F option to be invoked if dump hits a write error.

You can contact me at chris_maden at yahoo.com if the
above is not clear.

Sounds useful to have such a feature.

I may even implement it if/when I found some spare time
(which may not be in the near future though).
