The way backuppc stores things it doesn't matter whether you keep fulls or incrementals. Any number of duplicates will collapse to one pooled copy anyway. With xfer methods other than rsync, doing a full will actually transfer everything, then discard and link duplicates. However, with rsync a full just uses the rsync algorithm to compare against your existing copy so only a small amount of bandwidth for the block checksums is used but it does take longer since it reads every file. An rsync incremental skips any files where the timestamp and length match what you already have so it runs faster but since the comparison is always against the last full the amount of data copied each time keeps increasing until you do another full run. You need to balance the time vs. bandwidth to match your situation. It has worked for me to do weekly fulls and in some cases I do a manual full run on Friday once so they'll span into the weekend if they ever take too long. -- Les Mikesell [EMAIL PROTECTED] ------------------------------------------------------- All the advantages of Linux Managed Hosting--Without the Cost and Risk!
