Speeding up comparisons over WAN

murrayg@skillhire.com.au · Guest

I have a number of replications being performed over a WAN. The ammount of data being replicated is typically low, bur the number of files being compared is high.
This means that the time taken for comparison far exceeds the time taken for replication.
Is there any way of speeding up the comparison process?

A daemon on the remote machine that tracks changes is the first thing that comes to mind.

Regards

One option is this one:

Thanks for that - the problem there is that files may have been added updated etc. So I presume a rescan would then be needed

Would files change on the remote too or it's a one-way replication ('push') where files change on source and are pushed to target ? thanks

It is a one way replication - pull.

Vice versa is on the target machine and it replicates (augment) from 8 different source machines over the WAN (30kB / sec throttle)

The actual updates take about 20 mins, the compare takes about 8 hours

You would need to install on the 8 source machines to make use of the no rescan option. In that case it would not be needed to rescan the target each time, which would ave a lot of time.
