Hi again, I was just going to add that your subject is incorrect, but I see that you seem to be having a second issue. Sorry for replying a bit hastily, but your wording does make it rather easy to draw incorrect conclusions (or rather miss essential points).

Note that "pool" also means "downloaded again". Not downloaded due to rsync savings is "same" (in a full backup) or the file simply not appearing in the log (in an incremental backup). > But those files marked as "create" haven't changed since the last run, > timestamps are still the same.

It is *possible* to modify a file without changing the timestamp (e.g. resetting it after the change). But that is probably not what is happening here. It would appear that pooling is only *partially* working (which is confusing in itself). You couldn't have files marked "pool" if there was no pooling at all. I would *guess* that you have probably incorrectly changed $TopDir after having made some backups. You probably have tons of "link failed ..." errors in your log files. New files are not added to the pool, so only files already present from your first backups would be found there, though linking would not work for them, either. Again, for anything more than educated guesses about what might be going wrong, we need details about your setup. - What version, what installation method, what OS, which paths, which filesystem(s), how partitioned? - What did you change recently? Move $TopDir? How? See http://sourceforge.net/apps/mediawiki/backuppc/index.php?title=Change_archive_directory for details on what you should or should not have done. - Is there anything suspicious in your log files ($LogDir/LOG and $TopDir/pc/hostname/XferLOG.NN.z)? > This results an an extensive amount of traffic, which is unacceptable. Err, no. It results in an excessive amount of storage being used. Traffic is independant of storage. If pooling was working correctly, you could still have the same amount of traffic, but everything should be marked "pool" and stored only once. Conversely, if rsync transfers were working correctly, you would save traffic, but that does not imply that pooling would work. True, for this one host unchanged files would be re-used, but they would not be matched up against independent copies of identical content (from the same host or different hosts). You need to fix both issues, and they are independant of each other. Regards, Holger ------------------------------------------------------------------------------ Come build with us!
