from a quick scan of the code surrounding occurrences of "RStmp" in BackupPC, it seems that for rsync transfers an uncompressed copy of any compressed pool file > 16 MB that has actually changed is made in order to build the new file with a minimum of bandwidth usage. This is necessary if unchanged blocks of the file are detected in a different order than they appear in within the file, because a compressed data stream is not seekable. I have no idea why they *would* be detected out of order, but I expect the code would not provide for this case if it couldn't happen. > I have one Linux share, about 6TB uncompressed, over rsync, which > backs up nearly to completion, then BackupPC (3.0.0) spends 3-4 hours > repeatedly copying RStmp files to the base of the current > > .../pc/<client>/new/f%2f<sharename> > > the RStmp files are from 1 to 3 GB in length, and I have had no > success correlating them to an actual file. It appears they end up in that directory for any file in the "share". So, you're looking for files in the "share" between 1 and 3 GB (uncompressed size) that have changed since the previous backup. You might look at the contents ('file .../pc/<client>/new/f%2f<sharename>/RStmp' can give you an idea what sort of file it is). Hope that helps.
