should set nice level

[Thomas Guettler]

If I run a backup, the whole system is slow. I think the backup process should set a nice level (and ionice), since it is a background job. The interactive processes (terminal, webbrowser ...) should not be slowed down by the backup process.

[Michal Zubkowicz (michalzubkowicz)]

Currently it's 10 so it's slowing down other tasks, it should be something like 19

[Kenneth Loafman (kenneth-loafman)]

Use *ionice* instead. Try "sudo ionice -c 3 duplicity ..." to set I/O
class to idle.

I know how to use ionice. I want sane defaults. Duplicity should set the maximum ionice+nice level itself.

[Kenneth Loafman (kenneth-loafman)]

Actually, it should have an option to do this. *duplicity* is made to be
run off-hours with a cron job while users are not on the system. Unlike
interactive backups, there is no comprehension of user activity.

What happens if duplicity runs with maximum nice+ionice during off-hours while users are not on the system?

[Kenneth Loafman (kenneth-loafman)]

Not a lot different unless you have other cron jobs running. They could
keep it from finishing on time, but thats about it.

Will have to investigate how other backups handle this. Can't really think
of a downside.
