Don't run when off AC power

[Adam Porter]

Binary package hint: backupninja

When using backupninja on a laptop, it would be nice to be able to choose to not run certain jobs when off AC power. I don't want to use my limited battery power running a backup, I'd rather wait until I plug the system in.

I have modified backupninja to check if a job is not supposed to be run on battery power, and if not, if the system is on battery power. It checks for a "runonbattery" option (which defaults to "yes") in the main section of each backup job's config file in /etc/backup.d, and uses "acpi -a" and grep to check the power status.

I'm not sure of the right way to supply a diff, so I will attach /usr/sbin/backupninja, changed from 0.9.4-6ubuntu4. Then the default config file should be updated, and ninjahelper too, I guess, though that's over my head right now.

Hopefully this can be merged into Ubuntu and Debian. I'd suggest upstream, but it hasn't even released 0.9.5 yet, though it's had several changes since 0.9.4.

Thank you for taking the time to report this bug and helping to make Ubuntu better. To get your fix included in Ubuntu, it would help if you tried transforming it into a debdiff (http://wiki.ubuntu.com/PackagingGuide/Recipes/Debdiff) and submit it for review (http://wiki.ubuntu.com/SponsorshipProcess). If you prefer somebody else to do that, that's fine - please just indicate if you're available to do that.
Another good way to get this patch included in backupninja could be asking upstream and check that the software developer(s) like(s) your patch. This way, this will be integrated in Debian and then synced in Ubuntu.
Please, re-subscribe u-u-s once done.

I have the same problem with Ubuntu 9.04.
My notebook is an HP dv6000 series, the model is hp dc 6725us, and with Nvidia.

We're sorry that we do not always have the time to look at patches. Thank you for your patch in fixing this issue. It would be great if you could forward this patch upstream and hear their thoughts on the patch. Also of note, it would be great if you could submit a diff since its easier to see what was changed between the versions.

From upstream bug tracker:

"Those interested in implementing this requested feature shall have a look to past discussion about it on Debian bug #466193: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466193.
An already working (quite elegant) workaround is also documented there."
