Disk space is pretty cheap these days, but I suppose that depends on the size of your database dump after compression. I'd recommend translating the concept into the dollars it would save to see how much effort it is worth. > I know a commercial solution based on this feature: > one of the claim is that the incremental backup > becomes so low in terms of volume of data that it > easily enables for remote archiving with a classical > high speed internet connection! Rdiff-backup has this feature, but you lose compression and pooling of common files across machines. http://www.nongnu.org/rdiff-backup/ > So may I ask again: is it (could it) be planned for a > future backuppc release? The idea has been kicked around on the mail list before, but so far I haven't seen any plans mentioned. If it is enough of a problem to be worth the effort you might exclude the directory holding your database dumps from backuppc and run rdiff-backup there instead. -- Les Mikesell [EMAIL PROTECTED] ------------------------------------------------------------------------- Take Surveys.
