I think this may depend strongly on the use case. I'll describe my 
sitiation to get this started:

I want daily backups for my laptop, which go to a server and thus depend 
on network connectivity. I hacked a script that runs hourly through 
cron, and if no valid backup exists for 'today' it initiates a new backup.

It's made for sbackup (sorry), and relies on the presence of logfiles 
(that I hacked into sbackup) to check for succesful completion of a 
backup. It actually checks for an error line ('^E: ' regexp match) in 
the logfile, so in case a backup was still running (and no error was 
reported) no (new) backup is started. I can make it available to you as 
template for further development if you like.

This works for me, because I'm usually online for hours on end in the 
daytime (at work).

What you probably do not want (and in my case due to firewall 
restrictions happens to be technically impossible), is that a backup 
starts when you're online on a mobile wireless network. In that case 
either the network bandwith would be too limited, and/or you don't want 
to pay to send your 10's or 100's of Mbs backup data over a costly 
wireless connection. ;-)

[Nssbackup-team] [Bug 601579] Re: [Feature request] Separate backup frequency from crontab frequency

2010-08-12 Thread B.J. Herbison
Checking for connection type/speed is useful.

On a somewhat related issue, I backup from home to a network device.
When I'm away from home the device is not available. I put up with the
error messages backup started/backup failed, but it would be nicer if
I could say not being able to reach the backup device is normal, be
totally silent in that situation.

Of course, for all cases (drive not available, slow network connection,
or anything else), it would be nice to be notified if no backups had
been possible for a week so I could fix the problem or change the
requirements.
