Hi Dave, does each client individually take so long, or is it just one? (Or perhaps one client is taking almost all resources, so the other one is slow.)
If both clients suddenly have problems, an issue with the BackupPC server is likely. Otherwise, I've seen similar issues when suddenly some service on the client decided to include a virtual memory map file somewhere in /var/run. Which pretends to be of **huge** size, like 2 TB or something. And I didn't use the -x, --one-file-system flag for rsync. The file mostly consists of (implicitly represented) zeros and compresses really nicely, so BackupPC doesn't choke on it, technically; but the processing takes forever, and eventually it always hit some timeout. So I recommend a `sudo find /share -size +1G` to find potential huge files that you don't expect to be in the backups. Or try `sudo ls -l /proc/$(pgrep rsync)/fd` on the clients during backup and try to see whether rsync still progresses, and if not, on which file it idles. Same for tar, obviously.
