Getting rsync to store timing information in its logs

[Elliot Wilen]

Rahul,

My method, which may be primitive, is to call "date" immediately before and after running. Something like:

20 22 * * * date >> /var/log/mysync.log; rsync -av foo bar >> /var/log/mysync.log; date >> /var/log/mysync.log

Sorry, can't help with the bandwidth question.

Regards,

Elliot Wilen
