Very slow backup with no change

Post by svicar »

I made first backup, when I start next backup with no changes on folder it take almost 15 minutes to do nothing
What can be wrong?

I guess this is an incremental or differential backup? Are you using the Archive attribute for the tasks?

I see that it taks 14 minutes to process 15270 files. I guess the most of time goes by checking the existence of 15000 on the NAS,,,,Hmm.

You can speed up a little the process by no copying the attributes and the timestamps.
