Hum...backup for the 770? yea dd.
didn't penguinbait do any easy tool set for the 770?
I know he did all kinds and varieties ...and if my memory serves I thought he did something for the 770.
the n800/n810 has console tools v1 and the like which has reallll easy peasy backup tools...

In a slight aside..
One thing I am finding rather alarming in general that I have been noticing lately...is that web searches which I have quite constantly done...virtually daily ...for years...rather suddenly are not returning much at all on the exact same maemo topics that they did just a few months ago. Where there would be scads of pages...I'm lucky if I see 1 or 3 or 4 pages of results in some cases. little unsettling that...like the search engines don't want to spit them out...
