Re: [BackupPC-users] Viewing detail of a backup in progress?

Determine how far along the backup is in terms of % would require some sort of total size determination before the backup begins. I'm not sure if this is something BPC does already on the backend or not. At least keeping track of how many kilobytes/megabytes/gigabytes have been xfered so far and making that readily displayed in the web interface would be very nice. It doesn't have to be super precise.

Also lsof -p <rsync pid> can show you which files are open. Similarly
for the server on the backuppc system.
