[rrd-developers] announce: utility to restore RRDs from backup into used RRDs

[Christian Theune]

Hi,

I hope I didn't re-invent the wheel, but I could not find an existing 
utility that helped me out.

Our situation was that we had backups of our RRDs from a pnp4nagios 
setup and had to perform a disaster recovery in two steps:

1. Get the monitoring system started again (which then started
    gathering new data into new RRDs)

2. Get the historical data back from backup.

I wanted to minimize the time that we lost data for and thus wanted to 
merge the data from both RRDs into a new one. I found merge-rrds which 
wasn't quite what I needed so I adapted it and if anybody has a similar 
need you can find my shot here:

Comments and criticism welcome,
Christian
