Hello,

I've got a number of Macs on a LAN that I want to back up to a single file server on the LAN, and I might also look at backing up a remote machine to the server. Assuming I use a different archive for each Mac, I was wondering if you can tell me if there is anything I can do to minimize bandwidth utilization during the capture process. What I am really wondering is how QRecall verifies that only portions of a file have changed. Does QRecall have to verify the existing file in the archive (meaning, download it to the local machine where QRecall is running), put it in memory, then scan the current version of the local file, find the changes, and then upload them? If so, I am concerned that backing up multi-gigabyte files will use a significant amount of bandwidth each time it updates a file in the archive, even if the delta is quite small. But I really have no idea if this is accurate.

Do you have any suggestions on how I can keep bandwidth utilization to a minimum? I guess I already assume it would be best to run the verify/merge/compact actions directly from the file server rather than the local machines, but I wonder if there's a way to help the capture process.

Thanks so much.
